Hi Max I have a 2014 triton with over heating issues. I by passed the egr cooler which proved to be the cause of the over heating. My son also has a 2013 triton with overheating issues, so after doing the egr cooler by pass it still had over heating issues. Good news is mitsubishi will warrant the defect and replace the engine under warranty. Thanks Max as we would never have known this without your video. Gratts61

What coolant has been used and what ratio has been added? Did you see the recall information listed in the description? I hope some of these questions can help you find the fault. MiracleMAX

Well done diagnosing the fault, however replacing the ERG cooler was a waste of money! I would have left the bypass hose connected and install an EGR delete cable and put a blocking plate on the cooler to stop the exhaust gasses going through. This also has the benefit of stopping that disgusting exhaust from going into the intake and destroying the motor......

[@MiracleMAX]

Hey Fox Md, Thanks for your comments. While your suggestions may be what is considered the ideal solution, as a technician and business owner, I can not do or recommend these sort of repairs as they are illegal due to emission standards. The EGR system is used to reduce NOx gasses being released into the atmosphere which helps create smog and acid rain that damages our environment. I appreciate your thoughts. MiracleMAX

Right now there are 45 erupting volcano's globally, these volcano's will pump out more C02, NOx gasses and create more smog and acid rain in one hour than man can create in a year. I know the Government will tell you it us and that's why we need to have another tax, but giving the government more money won't change the environment.

[@Chris_cee]

Great video! What temperature range should these engines run at?

[@MiracleMAX]

Hey Ricky Bobby, That is a broad question. The thermostats are generally 82', but due to a lot of overheating issues with the 4D56, they recommended changing the cap to a 127kpa & altering the coolant mix to 50%, rather than 30%. forums.whirlpool.net.au/archive/2327089 That being said, I have had the temperature reading on the scan tool up to 96' in the workshop. I have also listed the recall information in the description above. MiracleMAX

[@vaneshmohit6750]

Hey Max. I have a 2013 triton with 4D56 engine. I had the overheating issue back in January this year. The mechanic cleaned the radiator and filled it with coolant. It worked fine until today it started overheating again while I was doing a long steep mountainside road. Do you think if I change the radiator cap and fit it with a 127 kpa one will remedy the issue?

[@MiracleMAX]

Well I guess it might be worth looking at this video next. kzbin.info/www/bejne/qpTXh6Wgacd5aM0

[@Dan.U.]

I don't understand the relationship between Turbo waste gate and the coolant leak / heating problem. Can you explain please?

[@MiracleMAX]

Hey Dan.U, That's a great question. If we open the wastegate or disconnect the VGT actuator, the turbo loses a lot of it's boost, therefore there will be less pressure in the EGR system. If the bubbles change when this is done, reconnect it and the amount of bubbles increase, this could mean a leak in the EGR cooler. With less pressure in the EGR system, the pressure difference between the exhaust system and the cooling system will make the leak more obvious. I gave a link to a video in the description that explains it as well. kzbin.info/www/bejne/mHSYY6qah8ilY6M Thanks for your comment. MiracleMAX

Awesome video mate, you've helped me out a lot but I still have an overheating issue on my 2015 mn. I've had my radiator cleaned out, bypassed the egr cooler, done a full carbon clean, cleaned out the intercooler, replaced thermostat and done multiple coolant flushes but still seeing temps above 100 on a good day and 118 on a bad day. Have taken it to the dealer twice but they seem like they have no idea, I did suggest water pump but "apparently" they never go. Any help is appreciated, thanks!

[@MiracleMAX]

Hey Reece, Sounds like you've had the obvious things done. Firstly, did it change AT ALL when any of the above work was done? Can you see the actual temperature in 'live data' on a scan tool? Does it smell like it is getting hot or are you just going by the temperature gauge? Has the cooling system been pressurised, checked for leaks, pressure loss? Has the radiator cap been tested or replaced? Does it have any fault codes? Is there any time that it is worse than others, like going up hills? Does it get cooler going down hills? Does the overflow bottle fill up? Does the coolant level go down in the radiator? Have you checked the links noted in the description section of this video? You should be able to check the water pump operation by this procedure - kzbin.info/www/bejne/hHOQmahqnrBoY9E Let us know how you go - hopefully you can get it sorted.

[@reecemillzey7838]

@@MiracleMAX thanks for your reply, the temperature seemed to change a few degrees temporarily but it's back to how it was. I have an engine data scanner with live readings on 100% of the time. The system has been checked for combustion gases along with leaks and there is no coolant loss, the radiator cap had also been changed to the recommended. The fault code I keep getting when over temp is PO217. Going up hills or over 90kmph the temp goes through the roof, after 114 degrees the coolant flows into overflow and the temp does not decline unless I turn the car off and manually put the coolant back into the radiator. Also, if the temp gets up to around 110 I can pull over and hold the revs at 2000rpm with no load and it will slowly cool.

@@reecemillzey7838 Did you get a chance to look at the links in the video description? australiancar.reviews/reviews.php#!content=recalls&make=Mitsubishi&model=Triton&gen=685 These are exactly the symptoms you are experiencing. These engines did suffer from overheating. Mitsubishi tried to remedy the problem by carrying out a few low level repairs and modifications, but in the end, they replaced the engines due to incorrect machining of the block. I have the exact case here at the moment. I got the customer to go to our local dealer (it helps when I teach their apprentices..😊) and after several tests later and in consultation with Mitsubishi Australia, they have decided to replace the motor, even tho it is not within the recall VIN range or the year (this is a 2015). It even has 190,000 Km on the clock. It didn't happen overnight, but it did happen. But now, due to shortage of parts, it looks like they might have to wait for a month for another engine. BUT, you do have to make some noise. They won't just hand over an engine. You have to keep on their backs to get results. Print out the recall information and take it to them, keep ringing and my customer even rung Mitsubishi Australia to get things moving. It might be worth pursuing this path to get a result

Hi max. I have a suspected EGR cooler issue at the moment. Risky asking for advice on the internet I know 😅 But I'm at a loss.. I have a black sludgy substance building up on the radiator cap...It was brand new as of Friday last week so it's been on for 8 days.. The old one looked the same (I wish I could post pictures here so you could see how excessive it is) It's not getting hot, It's not using coolant and there is no milkshake machine happening in the sump. It's also a 2.5lt MN Triton, Auto. The turbo is a bit tired (soon to be replaced).. I replaced the head gasket and decked the head about 12 months ago.. I didn't deck the block but I did a bit of a wild job with a straight edge and some fine sand paper.. I have had this this to Fraser Island twice and hit some pretty rough tracks since doing the head gasket and had no issues... This has only appeared in the last 3 months or so. This one has me stumped. I hope it's not a cracked block/sleeve or something stupid like that. I might bypass the EGR cooler in the short term and see if that has any effect.. I am open to suggestions.

[@anonops1980]

Not exactly related to the video, but I have a question you might be able to answer. Is the turbo on the 4d56 (also) water-cooled? There is plumbing that circulates water through the turbo, but I heard that this was designed to heat the engine faster in winter, not to cool the turbo. I ask this because I live in a very hot country and I’m seriously considering isolating the turbo to help with cooling. Thanks in advance.

[@MiracleMAX]

Hey Shlomo Goldbergerstein , Welcome to the channel! The cooling hoses that you see are to keep the turbo cool. One of the main killers of turbos is poor lubrication followed by overheating.

Cheers MiracleMAX 😉

[@anonops1980]

@@MiracleMAX thanks for the answer! In case you or any of your viewers are interested, I solved the problem by performing the following: 1. Removed the hot air radiator (that goes to the cab), and isolated the water pipes that run there, therefore increasing the volume of water that goes to the actual radiator; 2. Isolated a little tube that circled water straight from the engine back to it, without passing through the radiator. No idea why this even exists. Of course that in some colder climates you can’t afford no heating, but it isn’t a problem in Brazil. My next step will be installing a bigger radiator with an electric fan, and that will do it for good, even in our 45oC summers, or so I hope. Also blocked the EGR valve because, well, why not? My 4d56 has neither a filter nor a radiator connected to it, and the exhaust gasses go back in the engine hot and unfiltered. Once again, thanks for the help. Cheers!!!

I have a 2011 challenger, same engine. These run hot, and a Mitsubishi recall fix was a 127 Kpa rad cap. I think the front positioned inter cooler may contribute to the overheating issue. I.e. 2 extra heat sources in front of the radiator and more resistance to air flow through them. The previous tritons had the inter cooler mounted above the engine, perhaps a better arrangement.

[@MiracleMAX]

Hey SLUGSLINGER, Firstly you need to determine if your gauge is working correctly. How many kilometres has the vehicle done? Is it petrol or diesel? Is the coolant level correct and holding pressure? Certainly, a thermostat could cause the symptoms you are talking about, especially if it returns to normal after a period of time. There are also other faults that could cause this as well. Here are some tests you could try shown in these videos. kzbin.info/www/bejne/fZu9gpmDeceCeNE&ab_channel=MiracleMAX kzbin.info/www/bejne/hWjXm39oitappLc&ab_channel=MiracleMAX kzbin.info/www/bejne/aXnWkmisbtqEndU&ab_channel=MiracleMAX Let us know if you find the fault. 😊 MiracleMAX

[@MiracleMAX]

@@theyorkshirelad. Thanks for sharing your repair. A thermostat is rated to open at a specific temperature and they will not open until that temp is reached. They use a wax pellet in the bottom, which expands when heated, opening the thermostat. They don't slam open, so it might appear to open slowly. If they open too early, you will end up with a cold running engine, no heaters and poor fuel economy, if it opens too late, the engine will overheat.

@@mebob5842 Since the heat should be removed by radiation to the ambient outside temperature, the bottom hose should be colder than the top. The cooler coolant will enter back into the water jackets around the cylinders to once again transfer heat via conduction (through solids) as well as convection (though liquid or gas). It's a continuous cycle of heat transfer. So, the bottom hose should be cooler than the top.

Rod out the radiator or replace? Should watch to the end oops, are there any consequences to leaving egr cooler bypassed?

[@MiracleMAX]

Some choose to do an EGR delete, but it is illegal. There are huge fines for both the owner of the vehicle and the workshop that carries out the work. However, heaps of people do it. I wouldn't do it as the vehicle is designed to run with the system. Fault codes will eventually be triggered if you leave the cooler bypassed.

@@MiracleMAX many people would feel duped into thinking they have purchased a diesel for longevity egr coolers are such weak points and it seems when a coolant loss is detected it’s too late even for the mechanically savvy.

@@MiracleMAX this is a great video of exactly what I'm dealing with atm. We have literally done everything you have done and our tests with the blue dye always return blue-green not urine yellow.

[@MiracleMAX]

@@benbuckler5375 What happened when you bypassed the EGR cooler? Has your radiator been checked for blockages? Has the thermostat been tested or replaced? Is your coolant at 50% ratio? How many kilometres has the vehicle done? You can end up with a blue/green tinge in the TK fluid, especially if it has been used before on other vehicles & then returned to the bottle. When there is hydrocarbons in the cooling system, the fluid will turn a definite yellow. Do you have pressure loss in the cooling system when hot? Is there coolant loss? Make sure that you put your pressure tester a little higher than the cap rating to stress out the system. Is the viscous fan working correctly? Has the water pump ever been replaced? So is the engine actually overheating or has it just set a code? By how much? Does it do it all the time or just when under load? What temperature is the scan tool telling you the engine is?

I have just had the same issue on my 2013-14 triton, have noticed recently that the heater works then I’ll stop turn it of then say 20-30min later start up and drive again and the heater takes ages to get hot again.. then all of a sudden today drove about 200-250 Ks got to my destination stopped for maybe half an hour or so then had to go down the road and the car felt like it lost power when taking off (maybe limp mode?) then seen the engine light was on and noticed the temperature was at about 3/4 on the gauge, I pulled over for a bit and seen the coolant had been spitting out of the overflow bottle, I then drove back home with the temp at normal half on the gauge but engine light was still on.. let it cool and had to top it up with close to 2 litres of water... The engine light disappeared and seem to run like nothing happened.. I then checked with a mates Gscan2 tool and it come up with P0217 code but had complete at the end of it? Do I have the same issue as what this car had or could it be something different? I would be so grateful if you could get back to me! Thanks

[@MiracleMAX]

Hey Josh, Thanks for your comment. P0217 code is Engine Over Temperature . That could mean a range of issues. In basic terms, it means that the engine has overheated. At this point it is important to start with the basics. The code is telling you that the engine overheated. Ask yourself - why? There was coolant loss - why? Any why was the coolant being forced out of the overflow bottle? How many kilometres has the engine done? So, as I said, start with the basics. Carry out a coolant pressure test. Leave it on for quite some time and see if there is some significant pressure drop. Have a REALLY good look for an external coolant leak. Use a light & use a mirror. Check inside the cabin where the heater core is. Does the carpet smell? Does the windscreen fog up. Is the carpet wet? Have the coolant hoses ever been replaced? Is the engine starting up on 3 cylinders and then eventually running on 4? Take note of the recall I have listed in the description above. Are there any bubbles in the radiator? Have you checked for a blown head gasket? kzbin.info/www/bejne/fZu9gpmDeceCeNE kzbin.info/www/bejne/hWjXm39oitappLc Have you removed and tested the thermostat? Is the radiator cap holding pressure? Is the engine fan operating correctly? What is the condition of the coolant? Have you tried bypassing the EGR cooler? Of course, follow any suggestions made in the video above. Here is a link that may be of use to you. www.obd-codes.com/p0217 I hope some of these suggestions might help you diagnose the fault. MiracleMAX

[@user-yr4om7kq6g]

MiracleMAX thanks for the reply, It hasn’t done it again since, but I noticed there is still pressure built up in the radiator when I haven’t driven it all day and I take the radiator cap of to check the coolant.. in your experience is that normal? I’m gonna start with a new cap and new thermostat and see if it does it again then try the bypass like you did if it happens again.. thanks mate appreciate it

[@MiracleMAX]

@@user-yr4om7kq6g You may not have noticed the recall information listed in the description, but here is the link again australiancar.reviews/reviews.php#!content=recalls&make=Mitsubishi&model=Triton&gen=685 Bypassing the EGR cooler is the easiest way to diagnose whether it is faulty or not. You don't even loose any coolant if you clamp the hoses. If the cap is faulty, it may retain pressure in the system even when it has cooled down. Just keep in mind, it's best to fit the updated cap which is 127 kpa, even though the spare parts guy might tell you differently. Just check out the link I have sent. Thanks for keeping us informed. MiracleMAX

[@user-yr4om7kq6g]

MiracleMAX I did read this previously, I’m guessing that those recalls had been done cause my cap has been changed to the 127kpa.. so would i be better putting a piece of pipe from the inlet to the outlet on the egr bypass so it still flows through? Or just clamp the hose shut so nothing at all flows through?

[@MiracleMAX]

@@user-yr4om7kq6g You can't just clamp the hose. I just suggested that you clamp the hoses, so you don't lose coolant while you create the bypass. Just like in the video, fit a bypass hose or pipe and run it for a week or so to see the results. I hope that makes it clearer.

[@rickdanielvillanueva3268]

Is it okay to bypass the egr cooler or it does have a long term effect on the engine itself?

[@MiracleMAX]

Hey Rick Daniel Villanueva, Thanks for your question, The EGR cooler cools exhaust gases before they go into the intake system. This helps with the reduction of NOx, a very harmful gas to the environment (it contributes to 'acid rain') that is developed by the high combustion temperatures. Apart from being illegal, disconnecting the EGR cooler will raise combustion temperatures & therefore NOx. If your vehicle has a turbo with temperature sensors or a DPF, these higher temperatures may trigger a fault code that will return, due to the parameters being met by the higher temperatures. Also, with higher internal combustion temperatures comes more stress on the engine components such as pistons, rings, valves, cylinder head etc. I hope that helps to answer your question. Cheers MiracleMAX

[@roshanchitan1997]

@@MiracleMAX egr is only used at low engine loads, how is it possible that EGT temperatures at low load exceeds the ones at high load? Because thats the only way a delete could cause more stress on the engine.

[@MiracleMAX]

@@roshanchitan1997 Hey Roshan Chitan, That's a great question! It's taken me a little while to do some extra research and I also contacted some friends who are far smarter than I am. Part of the reason for the lower EGT during lower engine loads with EGR operation is that the EGR system (prior to the turbo) is designed to lower not only combustion temperature, but also pressures, which result in lower NOx emissions. Many forget to take this into consideration when doing an EGR delete. Another thing to consider is that the EGR gasses are a better heat sink than just normal intake air. It is true that the opening of the EGR will occur during lighter engine loads, but the EGR system is also used as part of boost control, particularly variable vane designs, which is during high load conditions. I guess many people think an EGR delete is the answer to all their problems, where they may be forgetting all the other functions it carries out. I hope that has answered your question. MiracleMAX

[@roshanchitan1997]

@@MiracleMAX i understand that the software map was written while taking EGR gasses into account which when deleting upsets the system. So when deleted a proper remap is adviced? I deleted my 4d56. No cooler on the mechanical 4d56, cleaned out lots of gunk from the intake ports while the cylinder head was off(i'd say it was roughly 40% clogged).

[@MiracleMAX]

@@pb8582 So were you able to try some of the suggestions in the videos I Iisted above? I gather the radiator cap has been replaced. Was the radiator a new one or second-hand? The symptom that you have is typical of a partially blocked radiator. Do you have bubbles out of your radiator when you have the cap off at idle as well as higher revs - 2000 RPM? Are the bubbles consistent or occasional? Does your engine use an EGR cooler? Has the water pump been checked? To test the flow of a water pump without removing it you can: 1. Disconnect the heater hose between the cylinder head and the heater core. 2. Block off the heater-core pipe with the blanking cap. 3. Connect the pressure gauge to the disconnected heater hose. 4. Remove the radiator cap and start the engine. 5. Bring the engine to roughly 2500 RPM and monitor the pressure gauge. A good water pump should produce about 10 to 15psi of pressure. If not, this test has provided enough information to take the next step - removal and examination of the water pump and impeller.

@@pb8582 Probably a little far.... You need to do a TK head check to confirm a head gasket. What sort of cooling does the EGR use? Is it a heat- exchanger? Is there an oily residue in the coolant? Does the engine push excessive amounts of coolant into the overflow bottle? Is it just the bubbles you are concerned about? What is the pressure on the cap? Is the fan operating correctly? It looks like they use a viscous fan.
