Triton MAJOR Overheating Issue

Years ago, the Mitsubishi Triton with the 4D56 engine used to be either loved or hated. Some complained about them and others said that they had trouble free motoring apart from normal maintenance.
All that changed a few years back, when they manufactured a batch of faulty engine blocks that has plagued Mitsubishi until today. But the good news for you as a customer is that they will honour the warranty with this issue if you take it to the dealership to be diagnosed - if it is that particular fault.
In this case, the customer followed the direction given to him with a positive outcome.

Thanks to watching your Video I had coolant coming out of the overflow for about 12months and could not work out why? Finally overheated a couple of times took it to my mechanic and he said he could not find any issues. After overheated a few more time I took it to mitsubishi dealership and after a bit of back and forth they finally approved my new long engine replacement! Took 7weeks to get the result but very happy! Thanks Max for making this miracle possible 🙏

Hey Max My 2014 MN GLXR has been overheating for months and myself and my mechanic are pulling our hair out trying to figure what’s going on. But after watching your video I took it to my local dealer and 2 days after booking it in for a diagnostic and stress test I just got word today they are doing a long motor replacement!

Hi mate, the long motors come with new injectors already installed. That's why you get new pipes, old pump is used and long motor comes with a timing belt just not fitted so the dealership has todo the timing and valve clearances also Enjoy your content! Keep it up!

Hey Mate think mine has done it now but is 1 2014 model and 160,000. Did you have any pushback from Mitsubishi saying they were not going to be replaced? Also, any modification on your triton or fully stock as I heard they will use any excuse not to swap out a bad motor. Cheers

Hey Alison, I'm not sure of the VIN range for the fault, but Mitsubishi seem to be lenient with what is warranty, as long as it displays the same symptoms. Best thing you can do is take it to the dealership and explain that this is a known fault and you would like it diagnosed for warranty.

[@scottvarley7127]

Hi Max, Just wanted to say a massive thank you for your video on this. The details you highlight that this vehicle had was exactly what my 2013 MN had. The short story is, I was driving up the Sunshine Coast towing my (just) under 750kg camper in 4th gear most of the way (averaging 2800rpm), 1.5km off the highway, the temperature increased just below red and engine light came on, IT WAS BLOODY QUICK! Sitting on the side of the road, I watched this video and thought "Yep, this guy is all over the issue". Got it booked into a Mitsubishi in Brisbane and within two days, I had an approved long block from Mitsubishi and they even replaced the clutch at a reduced rate, as they already had the motor out. Pretty good feeling that Mitsi come through for this stuff and I am thoroughly impressed. I do want to ask though, would you recommend getting a fuel filter and catch can fitted with this brand new 4D56? I understand dealerships do not like you doing it. But I cannot for the life of me figure out why? Mate, thanks so much again. I recommend your channel to everyone now.

[@MiracleMAX]

That's great news Scott! I have found that Mitsubishi has been reasonable with this issue. It's a shame that this has happened and turned into such a problem. Obviously if they don't have to pay for the repair that is understandable, but when the time comes, I have found that Mitsi has been pretty good. Sometimes the dealerships have created problems, but not necessarily Mitsi themselves, I have fitted quality catch cans to several Tritons with no issues. I always get the specific fit ones as they are easier to fit and looks heaps more professional. A local earthmoving company where I teach the apprentices, always fit a secondary fuel filter as a matter of course. They are internal vehicles just for the company, but never have had an issue.

[@KiatYang]

Hi Scott, may I know which Mitsubishi dealer in Brisbane that you went to that have your engine replaced? Thanks

Hey Mate, great news! I am about to start this journey. My 2014 MN GLX has overheated 3 time in the past 3 months. After my mechanic replaced the thermostat its still spewing out of the reservoir and overheating. I have booked it in with Motorama for it to be diagnosed. Are you able to give me any advice or guidance or how it might play out? And @MiracleMax thank you again for uploading this video me and my mechanic are grateful

[@jamesm2099]

@QueenStreetCowboy firstly i prayed and asked God to help. Then i very politely made it known what i thought the cause was aka very well known issue and they tested it. Took them a few days to test it to prove the failure. Then sent away a request which got approved for a replacement. All up took about a month or so to be sorted.

[@QueenStreetCowboy]

@@jamesm2099 well I did the same and prayed too hhah. But like you I was polite and let them do their testing. After 2 days since they did the test I got told today they are replacing the motor. Thanks again for your feedback

[@aaronbozhang]

Hi MiracleMAX, Sorry for the late update. I got my MN Triton back a few weeks ago. After most of cooling system components get replaced. There is new thermostat, new coolant, new water pump and new timing belt etc. The car is no longer overheating for the first a few days after I got it back. However, the needle of the coolant temp gauge started moving up later when I was driving. It didn't reach the red line but it moved to 3.5/5 and 4/5. I was thinking "holy crap" and why is it still overheating if it passed the stress test and all the components have been replaced. And when I was throwing my anger at MMAL by posting in the newtriton forum, one of the bloke there he suggested me to drive the car with an ODB2 reader because the gauge may not be accurate. And I did accordingly in the following trips. I found the CTS data from the ODB2 reader is always between 84c-90c which is safe. But the gauge needle do move a little when the temp goes up even the temp is still within the safe range. After proving that although the gauge is flutuating but the car is actually not overheating many times, I thought the overheating problem is solved. Yestoday, when I was trying to figure out why my MN triton's trailer break is not working properly. I found the main "earth" connection from the battery's negative terminal to the car body chasis is not connected at all. I think when somebody replace the battery they left the connection undone because the cable is a little short for the bolt to connect. So the car's negative terminal is not connected to the frame. Actually I have noticed this long time ago but I thought this may not affect the car's operation. So I found a long bolt and bolt the connection on so the negative terminal of the battery is connected to the frame. Guess what. After I did that the temperature gauge never moves once it reach the middle. Interesting! I will drive more with the car to confirm that and try to figure out why my trailer break lights not working.

[@MiracleMAX]

That's great news & a great idea to look at live data while driving. Electrical components can do crazy things when there is a poor earth or no earth at all. I hope that has sorted all your overheating issues. Thanks again for sharing your updates.

[@abdul-kabiralegbe5660]

About the stress test involving running the engine at 3000rpm for a while and then backing up the throttle resulting in the head gasket failure. I'm curious as to the mechanism of the gasket failure. I imagine that the heat (and/or pressure) generated during the stress test causes the gasket to deteriorate enough to ( in conjunction with the wrongly surfaced block) allow the combustion pressure to leak into an adjacent water jacket. Any thoughts? Thanks for the video!

[@MiracleMAX]

Hey Abdul-Kabir Alegbe, I believe that it is the combination of the build up of pressure and a higher temperature at the same time creates a stress point, which normally would not show after a road test, by the time the vehicle comes back into the workshop. Perhaps a higher pressure within the cylinder is created when on decel. I'm not actually sure. Thanks for your comment 😉

[@justnettled]

This is an old story now, but I have a 2013 Mitsubishi Challenger that runs the 2.5 Diesel which I have owned from new. I had the engine fail, and then replaced at 38.5k kilometres. The second motor failed after it has done 150k kilometres (190k kilometres on the clock). Did a reconditioned motor exchange. It has started presenting the same symptoms after 9 days of driving. I have heard the Mitsubishi story about the fault with metal occlusions in the head causing failure, and now the one about the bad machining of the blocks. I have come to suspect it is just a badly designed engine with some kind of fundamental floor. I understand the 2.4 litre diesel is a slightly modified version of the 2.5, and I suspect it was simply created to address whatever is fundamentally wrong with the 2.5 litre motor. I don't trust the 2.4 litre engine either, as I have started hearing gossip that it is presenting overheat issues as well. Since I am on my fourth round of this issue I would note that the overheat has typically occurred during long runs (200 to 500km trips in a day - which I do fairly regularly) and also the failures have always occurred as pairs. First failure I get the car back from a 'shop' with advice 'there is nothing wrong', second failure about two to four weeks later that is 'terminal'. Also three out of four failures have with a pattern of a) Drive car for 2 to 4 hours. b) Stop for a break of approx 45 minutes. c) Drive for 20 to 40 minutes and get an overheat event. Bottom line is I don't trust these engines at all, as nothing has changed in the pattern of failure for three different engines in the same vehicle. Oh - and as an after note, I rarely tow anything.

[@MiracleMAX]

I can only begin to imagine your frustration Justin! The earlier 4D56 had no overheating issues Have you taken your engine into a dealership to be assessed? It could still be classified as a warranty. Worth a try at least.

[@shaunhowlett8893]

Hi I'm watching from South Africa. I have a 2013 MN 2.5 High power 131kw when doing long hill climbs the heat gage climbs up a lot or when overtaking trucks etc. I took it to Mitsubishi East London (Eastern Cape - South Africa) they did the stress test but claimed it passed with no issues. I have a TJM outback bull bar on my vehicle and the service advisor said I most likely will not get a warrenty claim as the bull bar affects the airflow on the vehicle. I can bring the vehicle in to to be tested again and if it passes they will do a chemical block test to see from there however there is no certainty to whether they will do the claim. My vehicle has just ticked over to 280 000km do. You have any advise on a way forward?

[@MiracleMAX]

Hey Shaun, Since they have carried out the stress test, you need to consider other possible faults. Does the coolant get forced out the overflow bottle? Have other causes been eliminated? There is some extra information in the details below the video. Are there any external coolant leaks? Do you have to regularly top up the coolant level? Has the radiator been checked for blockage? Is the thermostat working correctly? Has the temperature gauge been checked against the readings on a scan tool? Is the coolant fan working correctly? Is there any coolant in the oil or oil in the coolant? Are there any fault codes present? As shown in the video, the TK head check (chemical) is not very successful with diesels. Are there any bubbles out of the radiator when running while hot? kzbin.info/www/bejne/qpTXh6Wgacd5aM0 Is the system still pressurised when cold? Was the engine running hot before the bullbar was fitted? How long has the bullbar been on the vehicle? Is the radiator cap a 127kpa? Is the coolant a 50/50 mix? Let me know how you go.

[@robertboyd321]

Yes the MN Triton's are a worry. I have one (2015) & the engine has just started getting hot but the coolant, thermostat & water-pump are fine & it has decent oil pressure too. I was thinking (praying) that it maybe a restricted exhaust system as everything else checks out fine. But the heat expansion & cooling contraction noises coming from this motor are so loud that they send shivers up my spine. And you can even hear the expansion noises while you are driving it, & in this Brisbane heat somethings got to give sooner or later.

[@MiracleMAX]

So have you done the testing procedure to see if it is a blown head gasket? Or maybe the EGR cooler? Does the overflow tank get pressurised? Any smoke on start up? Coolant loss? Have you had the radiator checked for blockage? Does the temp reading go excessively high?

[@robertboyd321]

​@@MiracleMAX Thanks MAX, All the above tests have been done and it seems fine. The temp always stays between 82 deg C & 84 deg C. The only part that seems to get abnormally hot is the vacuum pump. All checks including SCV fuel mixture & timing are fine too. No smoke on start or while driving, no coolant loss. The thermostat, full exhaust system & Viscous fan have been replaced. But it still makes super loud Horrendous cracking thermal noises while driving but it mainly does it while sitting after shut down. Actually when I'm driving it is so violent that I can feel the noise resonate through the pedals and the steering wheel. It also does it with heat-shields removed. I have tightened all exhaust manifold bolts as well and there are no cracks in it. The only other thing I can think of now is that maybe the engine oil cooler is blocked or restricted. So far this problem has got everyone beat, but I can tell that something has got to give sooner or later.

[@MiracleMAX]

@@robertboyd321 It'll be interesting to see what the actual fault is. Let us know what you find. How many Kms has the engine done? Is the turbo desired and actual boost in live data the same? You said that it is overheating, but 'the temp always stays between 82 deg C & 84 deg C.' What temperature are you referring to? Are you sure the noise is engine related? Can you hear the noise free revving - just in the workshop bay?

[@robertboyd321]

@@MiracleMAX It has done only 76.000K, Has a manual boost valve (Tillix) fitted and it boosts 19 PSI maximum, & there is no longer any lag which has been great. But I have tried it with the Factory Boost controller which doesn't stop the heat & noise. The heat I am trying to describe is the actual engine & accessories. I know they run hot but after a short drive if you spit or drop water on the vacuum pump the liquid sizzles & turns to steam, it will burn your skin too & you cannot touch the throttle body either because it is almost as hot. Now in my opinion that is way too hot. I will fit a new engine oil cooler this weekend & back flush the oil & water feed tubes and see if that sorts it out. A friend said that maybe a water jacket is blocked or maybe it has an air bubble caught in the front of the head, but I think the cooling Temp would rise if that was the case. I know that they are difficult to expel all the air out of the cooling system but I don't think that is the cause.. I will let U know if I either get it sorted or throw a match in it..

Hey ItzHarold814 , Despite some initial concerns about a smaller engine size, some have found this engine to be quite reliable. Of course they require the normal maintenance for CRD engines - cleaning of the intake system of carbon. Installing a catch can will help that situation. These use a shim style valve clearance and need to be adjusted regularly. These did have some issues with towbars and some 6 speed manual transmissions. I hope that helps 😁👍

[@hmatt814]

@@MiracleMAX Thank you very much. Would you recommend buying one? I plan on getting a catch can installed if I were to get a triton. I suppose my main concern with the triton is the chassis cracking. I’m not sure if this is much of an issue compared to the previous model triton, but it’s just one of those things I would constantly be worried about. If I didn’t exceed the vehicles GVM would this been an issue? For me this vehicle would be an everyday driver which I would only take off roading a few times a year at best. It wouldn’t be setup to be a touring vehicle if that makes sense. Perhaps just a bullbar, under body protection, dual battery setup, etc. Thanks

Having a similar issue with my 4D56. Late 2015 model & sub 100k on the clock. Found the gauge was going to 3/4 up when i was in traffic. Took my OBD scanner & as i drove, the coolant ran 93-96C but in traffic it went to 114C. Thats when I saw the gauge up to 3/4 up again. Checked the radiator was pretty low & the overflow reservoir was up to the brim. It seemed to blow the coolant in the reservoir but not returning it to the radiator. I took the excess coolant & syphoned it to the radiator & it took about 1.3L till the radiator was full & the coolant was down to MAX on the reservoir. I then changed the thermostat & radiator cap. Seems to be averaging round 93-97C running. I have seen it go to 107C in traffic. So it seems to still run hot but no longer to 3/4. Its winter so im concerned summer is going to be a nightmare. Did a few more tests & i can see some bubbles forming in the coolant when under load. Very minor bubbles but mechanic seems to think the head gasket has failed. Taking it to Mitsubishi but im concerned the supposed correction to the engine block machining pre-dates my engine & its out of warranty. At this time, i just want to fix it & sell it for a new car....butba new cars are a bit of a wait too.

You are doing the right thing taking it in to Mitsubishi. They will carry out the test (yours sounds like a prime candidate) and take it from there. The one shown in the video was out of the VIN range, but they honoured it anyway. If you get no help from the dealer, contact Mitsubishi directly and state your case. Say that this is a well known, documented warranty fault. I have had other viewers even show the dealers this video. Hope it goes well for you. Let us know the outcome.

​@MiracleMAX Update. I put it in 5 weeks ago. They initially had it for 2 days & I needed to follow up with them. They finally called me back & confirmed the motor needed replacing. Put in a warranty claim for me. Been calling weekly to get updates. Engine arrived 2 weeks ago. They initially said it should only take 2 days but it's been sitting there since and they said hopefully next week if not the following week. Happy it's being done under warranty but they aren't providing a courtesy car & they're likely not prioritising it. I'm keen to get it soon cause Wife is getting depressed not having a 2nd car and stuck in the house having to WFH most days. I'm sharing the kid pick up & drop off's with my Dad.

​@MiracleMAX latest update. I received the car back at 7.5 weeks later. I did contact Mitsubishi Australia last week to find out what they perceive as the normal turnaround for this work & they stated the dealer & service centres are "independently owned and MMAL are limited in dictating or interfering in their day to day". They did follow up but by that stage the service centre already confirmed when they'd get it to me. The only issue is, I asked for warranty & they said there is no warranty on the engine or workmanship as it was all done under "good will" & the official warranty on the car finished 3 yrs ago. They did say bring it back if I have further issues but I'm done with this car.

Hi Max, I have driven 337k with a few overheats over the last 100k km, would you think as a factory issue they may consider replacing motor as it’s out of warranty? I was considering using Chem-I-weld to plug up pin holes- any thoughts? Cheers, Andy

[@MiracleMAX]

Hey Andy, Firstly, DO NOT use a chem-i-weld type of solution. You will void any chance of warranty. As stated in the video, the best thing you can to is take it to the dealer for proper diagnosis. What have you checked so far? Is it using coolant and blowing it out of the overflow tank?

[@user-nz2es4zx9i]

Hi Max, as I was flushing out the system in preparation for the chem I weld I realised the cap was buggered, I put the only one I could get my hands on for now 110kpa with no glycol and it ran to down the freeway no trouble this morning, I’ll book it in for professional flush and testing and keep my fingers crossed. It has been towing where I’ve overheated in the past, my cap may have been breaking down over time.

2.5 4D56 turbo Diesel engine has a common over heating issue due to manufacturing defect. Mitsubishi didn’t recall all the triton and check and replace the engine block with the issue. What they did is a campaign to “cover it up” and delay the showing of the problem. I bought a 2nd hand mn triton(10yr old). And unluckily after 4 month the engine start over heating. I have an old 2005 triton Ute with 4g64 engine. Bought it at 10 year old with 150k on the clock. Now it is about 320k and 17 years old. It never missed a beat and other than normal wear and tear the engine is so reliable and that is why I trusted Mitsubishi and bought the mn triton. But it seems to me, Mitsubishi was doing the same thing as what takata air bag did by covering up the issue instead of correcting them properly. So if you are thinking of buying a second hand triton with 4d56 engine, be careful.

Hey bo zhang , If you scroll down in the details of the video, there is some information relating to the overheating issue.

[@aaronbozhang]

@@MiracleMAX Thank you very much for your reply. because when I bought the car from the dealer, it comes with a warranty from iwarranty. And if I want to make a claim then I will have to use their mechanics. I went to the mechanic and they told me that the viscous fan cluth is faulty and it needs to be replaced 1st. And if after replacing the fan cluth if it is still overheating. they need to send the radiator away and get it tested for blockage. I am still waiting for the warranty claim to be processed and hoping this will fix the problem. Finger crossed.

[@MiracleMAX]

@@aaronbozhang I hope it works out well for you. Thanks for keeping us informed 😊

[@aaronbozhang]

@@MiracleMAX Got the Car back 2 days ago and the car is still over heating intermittently after the engine reachs the optimum temperature. It seems to me that the temp gauge raises soon after the engine runs for a while. and then when it is idling. The temp will drop slowly. The mech recommended by the insurance company said he tested it a few km and let the car idled for half an hour and no issue. And he is blaming the used part approved by the insurance company.

[@MiracleMAX]

@@aaronbozhang Pass the blame........what's your next step? Is it losing coolant? Is there excessive coolant in the overflow bottle? No oil in the coolant and vice versa? Can you check your temp gauge accuracy with a scan tool? Did they do the fan as well as clean the radiator? Was a thermostat done?

[@gabriellejones4550]

I wish i had this video ages ago. Been dealing with this exact same problem from my 2017 triton. have fought and fought Mitsubishi over and over again in regards to the issues and never got anywhere. the warranty ran out just under 12 month ago but i have been having this problem for close to 3 years now if not longer and it's still not fixed. i gave up dealing with them bastards after i spoke to lawyers and all. Have spent thousands and thousands on getting it looked at from Mitsubishi to try and figure out the problem and they just keep blaming me. I always did the right thing got it services on due time and always done by Mitsubishi themselves. NOT HAPPY WITH THEM!!

[@MiracleMAX]

Sorry to hear you have had so much trouble. Have you spoken to Mitsubishi Australia directly if you are not getting help from the dealership? This is a well known, documented fault. You should not have any issue if they carry out the official test and find that the fault is a warranty issue.

[@rylandrickard8131]

Hi mate, I’m looking at a 2012 triton 2.5 turbo diesel single cab 2WD. Are these okay?

[@MiracleMAX]

I have worked on quite a few of these. Apart from maintenance items due to age (injectors, egr, turbo, etc at high kilometres), my customers have found these to be quite reliable. That being said, the obvious overheating issues happened in some of the models. I have included links etc to helpful sites in the video description

[@ahmedabdullah8700]

So if i just bought a 2013 late 2023 and the engine fails will mitsi replace the engine?

[@MiracleMAX]

That's up to Mitsubishi. If it fails due to the common overheating fault, I have found them to be quite helpful trying to remedy the issue. The later models do not have the 4D56 engines & did not have the same problems.

[@aaronbozhang]

What they are trying to do is covering up instead of correct it properly. If it is out of warranty then it will be a big problem for the second hand owner.

[@MiracleMAX]

Just as in the case of this vehicle, it was technically 'out of warranty' as well as the VIN was not within the assigned code, however, Mitsubishi is helping out in some areas with this overheating issue - you just have to push and don't take no for an answer to this common fault.

[@joshring1770]

My 2016 mq 4n15 does the exact same thing had to test etc done came back negative unfortunately I don't think Mitsubishi will cover it

[@MiracleMAX]

I am seeing quite a few comments like this. The testing procedure is very specific and Mitsi will only replace what they have to. Dealerships will vary in helpfulness as well. Just keep in mind that the faulty engine is not the only reason the engine will overheat.

[@BB-sv1in]

In theory , would waterless coolant prevent this issue arising??

[@MiracleMAX]

Coolant has a specific mix that should be used. If exceeded no value is gained. In fact, pure antifreeze lacks sufficient heat capacity to keep the engine cool and the heat-transfer capabilities are lowered by 35%, which could cause engine damage. What we are looking at with the Tritons, is a manufacturing design fault.

[@TinaFOTZE]

Exact thing happened to mine. Bought it second hand 🤦🏻‍♀️ My mechanic told me to see Mitsubishi and they’ve been honouring them whether or not they’re secondhand. Booked in on the 26th of June, so fingers crossed. Otherwise I’m selling it. 😪 Sucks though, because it’s a nice car apart from this BS.

[@MiracleMAX]

Glad to hear they are honouring the warranty. They have had a real problem on their hands.

[@Jake-rz9ki]

How did you go?

[@TinaFOTZE]

@@Jake-rz9ki they couldn’t find any fault with it even though it kept overheating when I’d take it on long drives.. So instead of throwing good money after bad I sold it and bought a brand new one

[@Jake-rz9ki]

Hi Max I have a 2015 mq triton with these symptoms I has about 215xxx kms on the clock I bought it 2nd hand with 150xxx kms it has been doing it the whole time i have owned it. do you think it would be same issue and do you think it would still be in warranty or mitsubishi would fix it?I was thinking it was just the radiator not being able to keep up then I googled it and found your video now I'm curious

[@MiracleMAX]

Hey Jake, The MQ 2.4 did not suffer from the same problems as the MN 2.5. What testing have you done so far? Is the cap holding pressure OK? Is the thermostat operating at correct temperatures? Is the coolant ratio correct? Has the radiator been tested for blockages? Are there any fault codes? Is the engine running correctly?

[@Jake-rz9ki]

I'm having to top up coolant nearly every tank of fuel. I have taken it to radiator specialists and they say everything is working fine. They all replace the radiator cap and say try this this should help. They have done pressure tests and the liquid test like you have done and they have passed them. When I drive at 100km/h towing I might pull over and turn vehicle off then can hear the radiator bubbling into the overflow if I go on a longer trip the temp gauge will go up 1 or 2 bars if I'm not careful if I sit on 110km/h and am towing up long hills temp goes up very quickly I'm only towing about 800kg

[@Jake-rz9ki]

The pressure test and liquid test are all done when the engines cold is there a way to test when the engines hot not sure what to do

[@Jake-rz9ki]

I had a brand new radiator put in about 20000km ago done the same thing the next day the put a new radiator cap on and a new cap for the over flow and that was it still doing it

[@MiracleMAX]

@@Jake-rz9ki Losing coolant is not OK. Is it only when you drive distances that it overheats? Has a proper radiator flow test been done? Has the EGR cooler been tested? Are there any fault codes stored? Is the viscous fan working correctly? Does it blow smoke out the exhaust when overheating?

Ah, no! It should cost perhaps a standard diagnostic fee........certainly not that much! Did they use gold-plated tools?

The diagnosis test should only be around$176. Some dealers want to remove the block and see what is causing it and this charge would usually be between $1200,$1700. I would recommend you asking the dealer to just send the report for the stress test Mitsubishi Australia and see what they come back with

Hell Max. I am having very odd but similar complications with my 2015 MN triton. Long story short, it was over heating last Thursday night, on the highway w/ no load, 25 minutes of driving with cruise control on. after a local mechanic visit this Tuesday. Relevant tests were conducted showing no faults. Mechanic said it could be a thermostat on its way out. oil is fine and topped up, coolant is fine and topped up - no signs of bubbles, no leaks on the garage floor, no visible damage to anything. My triton has a 4D56UCFS7360 engine. The coolant is 50/30, the radiator cap is 127kPa, and when I bought it privately, the ex owner said the engine was remapped/modded/chipped what ever you want to call it. I am baffled with the knowledge I have based off my research, but what is worst my mechanic is just as confused. Any suggestions ?🫠

Probably should of watched the whole video before I commented… I have my ute booked into the local Mitsubishi dealership. Silly question, but would it be a good idea I tell them I know about the campaign 020116, and get them to do necessary fault finding checks anyway and go from there?
