Overheated after new Radiator! Tow In! Infiniti 3.5 EX35

[@Twisted4AGZE]

Probably the first time that radiator actually had pressure in awhile. Old one was probably leaking or not coming up to pressure so it didn't leak at the heater hose. New radiator got up to good pressure and found the next weak link.

[@PopllFixit]

My thoughts exactly

[@shak180]

This! Old car, you fix one leak and the next weak spot will show itself

[@Thanatos2996]

That's how it was with my old Jeep. Replaced the radiator cap, and suddenly it had the correct pressure so the water pump started leaking. Replaced the water pump, and wouldn't you know it, the radiator gave out.

[@Paul-oh4fe]

The broken barb was originally a bleeder valve you crack open when filling with coolant. Common problem on these VQ's for them to break. They make metal replacements that last a lot longer. Makes bleeding the coolant much easier when you have one in there. No bleeder valve when filling and that's why it took so long to bleed of air. Head gasket is more than likely fine.

[@TheFrenchPug]

That's good to know then.

[@shaunkelly9053]

Why is it overheating still then?

[@jimclifford1241]

Exactly right. That's a bleeder valve that needs to be replaced with something other than what our man Ray used. They are crap quality, even the new, replacement valves from the dealer.

[@Paul-oh4fe]

@@shaunkelly9053 Because there's still air in the system. You see how it kept bubbling even after attempting to bleed it for a while? The air is trapped in there and it's not getting out until it's bled correctly. Nissan has a very specific bleeding procedure for these engines. Basic idea is to crack open the bleeder valve and then start slowly refilling the system. As soon as it starts pouring out of the bleeder valve, you close it and continue to refill until the system is full. Then you blast the heat and do the normal procedure like any other car.

[@DaytonaBlueHr]

@@Paul-oh4fe Yeah but you should mention to not turn the car on yet. First open the bleeder valve with the car off and slowly pour into the fill funnel at the radiator neck until you see Coolant start to come out the bleeder valve. Then Close the bleeder valve and continue pouring until it stabilizes at the funnel and you cant pour anymore. Then you go inside the vehicle and turn it on and blast the heater on Max. Wait a couple seconds for the coolant in the funnel to get sucked in by the engine and continue to poor until it stabilizes again at the funnel. Their will be some bubbles from the air escaping dont be scared about that, but once you see that you cant fill anymore go back in the car and hold the Rpm’s at 3000 or so for 10 seconds and do this every 3 minutes to make sure all the air gets out the system. You basically just do that until theirs little to no bubbles coming from the Funnel at the radiator neck. Ive done this on my Hr so i memorized the entire process 😂

Hey I’m an Infiniti tech. That’s a common failure on the 3.5 and 3.7. If it’s broken or about to be broken, disconnect the evap line that’s right beside the heater hoses and take it out. Gives you more room. Then take the clamps on the heater hoses and push them behind the heater connector. Take pliers and break the connector in half. Then take both hoses, point them downwards, and use the pliers to crush the connector inside the hose, the pieces will fall out like confetti. Make sure all the plastic is out, then I use silicone lube in the new connector and push it into the hose. It takes me like 10-15 minutes doing it this way. Top off the coolant and don’t worry about bleeding it, I’ve never had a problem

Ray, put in my 2 cents after 45 yrs. I have used the funnel fill system you are using for years. Very small thermostat in that engine, will erupt coolant for a while. Put out side & cool off. Engine will take what it needs during cooldown. Fill & mark overflow bottle. With electric fans , it won’t take long to overheat , if it is going to. Remember , boiling point is 212 & for every lb. pressure on cap raises 3 degrees.your @ 213 no cap. Not surprised old plastic union split, @ hottest part of enclosed engine compartment. Great video again.

[@repaid1]

I'm not sure of your boiling points, but as I only have 40+ years of working on cars, mostly race engines...I will let that go your way. I will say that a 50%-50% mix of antifreeze and water is 223°F and a full on 100% Evans waterless coolants have a boiling point of over 375°F...I don't worry on my engine builds on the pressure difference as you specified so can't comment. I will dial in specific engine temps with applications being used with the thermostat.

Two things I thought of. Number one, make sure the interior heater matrix is set to hot (if possible, before the system is evacuated. Obviously not possible in this case. But it needs it anyway), as this will leave an air lock in the system which takes ages to "bleed" out, then stop. Just like,e your engine did just, when it took the coolant into the matrix. Number two, are the fans running on the back of the radiator, which would cause overheating when no air is passing through the radiator.

[@marekslemensky4531]

I'm also guessing a fan here. 1. can't hear it 2. almost no temperature difference between radiator hoses

[@Starchface]

Indeed. Perhaps the fans had not been plugged in after the radiator replacement, or were already inoperative. That could lead to abnormally high pressure and the failure of that component. We don't even know whether that was an OEM component. Note that the driver had just left the shop from the radiator replacement. I doubt that this was a coincidence, but the entire chain of cause and effect remains unclear. Who pays? We can only hope there is no engine damage.

[@MattExzy]

From my limited experience and younger, foolish DIY days of firing parts canons.. there was an instance of an overheating problem I had with an old Mazda of mine. New thermostat - didn't work. New radiator - didn't work. New fan - didn't work. Then I noticed after driving, it would gargle and grumble from the radiator and purge lots of gasses into the overflow - head gasket.

[@donmurray5900]

Hi Ray, The cooling system going into the heater is above the radiator and will have air in it. The plastic part that broke is not the correct part for that location. There should be an air/bleed screw between the hoses. When filling the rad with coolant the funnel that you use would be ideal as it need to be filled high enough to be above the bleed screw. If not, there will be air pockets in the heater system.

[@jamessayers253]

Some models don’t have one.

[@alisaleh6100]

That makes sense that was the issue I had with my heater blowing cool air. But like said Ray it might have blown the head gasket by now. Just have to wait until the next installment. Can't wait.

[@tobyrox9]

Isn't the radiator cap and the overflow tank meant to fix that air issue? Pressure builds and pushes air into the overflow tank and then when it cools it sucks coolant back in. I've only got old cars though, no clue if it's different on new cars.

[@keithlibner9259]

What I have found that almost always worked for me is to let the car sit overnight. Then, when it is totally cold in the AM, start the car and feel for pressure in the upper hose. If there is pressure on a cold start-up it is a head gasket. A good head gasket won't have pressure in the hose until it starts to warm up.

[@stephentimm4417]

Ray, Next time you run into this same problem, just use your angry pliers to crush the broken plastic barb, by wrapping the hose with a shop rag and then crush through the hose. The broken (and brittle) barb will then crumble apart inside, and you can then just lower the hose to flush out the pieces. I’ve done this many times. It is very quick and efficient.

[@That_AMC_Guy]

I found with cooling systems, (and today's crappy plastics) you almost need to replace everything at once. I have a little Tiburon that went in for timing belt service, and they of course suggest water pump service. Okie dokie. About a month later, the top of my plastic radiator starts cracking.... so replace that. Obviously replace rad cap. But all you wind up doing is finding the next part to fail. Get that pressure up in the cooling system and the next weakest part is gonna pop. I next had to do the throttle-body heater hoses and then a gasket on the block transfer manifold. ( I did the O-rings that connect the water pump to the transfer manifold at the same time because plot! ) Thankfully now my little car is holding it's pee.... but for a few months there it was all about patching leaks.

I saw this from another mechanic. He used the expansion bottle. covered the lid for a few seconds then quickly placed the gas analyser in the port without touching the fluid.

This is like the Ford Duratecs where they have reversed cooling systems and if you get air into the block, prepare to spend hours purging air out of it. Ford says hold engine at 2500rpm for 3 mins after thermostat opens, rev it up to 4000rpm for 5 secs then return to 2500 rpm for another 3 mins. Didn't work out well and the engine overheated. Tried what FordTechMakuloco said like 5 times and it stopped overheating. But everytime start from a stop you hear water moving inside the engine. Did the procedure like 10 more times and after 2 weeks of driving, finally there seems to be no air in there anymore. So yes, I think there are quite a few engines that are much better off vacuum filled.

Absolutely spot-on. These are not 15-minute wham-bam-thank-you-ma'am cooling system refills.

Makes it easy to reach in and shut off if something goes wrong and I really can't be bothered getting locked out of a running car. Happens to ya ONCE and never again.

[@landontakeamericaback2106]

Hmm should close off hose with a vice grip to keep plastic from falling down the hose into the cooling system.Its a murph’s law.

That's supposed to be a bleeder valve. This is a terrible video

[@storyteller619]

Well Ray just a little advice from an “Old School Shade Tree Mechanic” (I’m 66yrs young) Get yourself a king size pillow with a cover and lay it on top of the motor. I have in the past cracked a few ribs working on cars and trucks (I have a 4X4) and laying on top of the motor is an everyday type thing when working on them.

[@johncunningham4820]

Well this is a little mysterious so far . Car went in for a Cooling related problem and got a Radiator . Immediate Overheat again . Now Ray has it . I suspect the previous shop was too quick to sign off on the Job . They too , should have noticed the Purging problem . Some Engines can be difficult to " Burp " and there are sometimes bleeder valves fitted to assist that . I suspect a Warped Head .

[@harrywalker5836]

i suspect who ever designs new cars has a very warped head.. new car every 2 yrs,,yeehh,, lets be green.. ai still got a 62 f100 4x4.. no lithium/cobolt child murderes here..

[@LabCat]

As a fellow technician, one of the things I've learned - if you have to lay over / on top of something, always carry a nice piece of flat open-cell foam to lie or sit on. Great video as always!

[@bjverzal]

Ray - two thoughts. 1. The sound of the lift going up in the background as you were installing the manual prop rod. The hood went up as the sound of the background lift went up. 2. Surprised you waited to long to swap out the clamps.

[@adotintheshark4848]

use the OE clamps if possible. They expand a little with the temperature and don't dig into the hose, unlike worm clamps which don't expand and dig into the hose.

[@kdoggoutdoors]

The squeeze clamps do fatigue.

yeh lol i remmber the video where ray was like "dont use those damn screw type clamps" and im like but wtf if u cant change a cooling hose onthe side of the road why do they use those damn squeeze clamps! those things are always a PITA! I knew no pliers would make them easier! its like a precision strength challenge at the worst time!

[@onlyskillss9754]

The way I used to get the pices out was to clamp a few inches back on the pipe then use big pliers to crush the broke pipe inside and tip it out, works most times

[@georgeboukouvalas9781]

Has the cooling fans kicked in? Possible temps sensor for the cooling fans is shot

[@MrRadio1610]

if you ever have trouble putting a hose over a fitting ,, instead of a grease base spray, which will always stay slippery use brakleen spray it into hose and quickly slide pipe on.. it has always worked for me .. i am / was a heavy diesel mechanic until i crushed my foot last august

[@Davo_1991]

Also the oem clamps have already left a very solid impression on the rubber already, it would be best to reuse them and put them in the exact same position, using a standard wormdrive clamp can work but because of the impressions in the rubber it might not seal it flat, obv worked for you now but idk :/

[@scottybear6265]

Ray im sure this episode was much earlier what i do is squeeze the end of the hose and crush the hard plastic then dig it out if you worry about getting a piece of plastic where you can’t reach it put a vise grip on the hose and crush away.

[@thirtythree160]

Which went bad first? The radiator or the head gasket. Wild guess is the radiator had a leak and the car was over heated which warped the heads. Those aluminum heads will warp as soon as they loose cooling and it don't take much coolant loss for this to happen.

[@Bryan-Hensley]

At this point it really doesn't matter other than curiosity.

[@adubs.]

I suspect the same. This is probably at least the 2nd time that engine has been overheated.

[@wirefeed3419]

That model 3.5 Litre engine series were almost bomb proof. I would be surprised if it had a Head Gasket failure from normal operation and it has not been confirmed there is a head gasket failure yet, we will have to see what shows up in part 2. One thing I did not hear during the run time was the Radiator fan running. Part 2 should be good and informative.

here is some 20/20 hindsight, could you have tried running a suitable bolt into the broken piece and then pulled on the bolt head?

[@remyredert5670]

My thought was to stick a hook in and hook it behind the inside of the plastic piece.

I have. Sprinkler tool that takes plastic out of pipe. I wonder if that would have worked.

[@loneranger4175]

Pinch the hose shut with vise grips and use an easy out screw extractor bit to remove the broken coupling

@@remyredert5670 and run risk of stabbing a hole into the hose, unless it's got a smooth tip and you're careful.

[@jwat2396]

Just an idea, never take the hose clamp off in the first place. Squeeze the clamp and work it down farther on the hose. It will be easier to move it into position once everything is in. Just a thought.

[@jerrykinnin7941]

I'm continually amazed at how the engineers constantly make stuff so complicated. Good job Ray. Would it be a good thing to replace all the hoses water pump and thermostat when replacing a radiator?

In my opinion, if you follow that thing you will have to swap all car. That's just what you get for owning "old" car, slowly everything breaks apart/wears out.

I have a pair of pliers that makes removing pieces of broken pipe fittings much easier. They were sold as Reverse Pliers and they have hooks pointing outward

Smartest choice I made was buying a lexus over an Infiniti. Nissan has been really dropping the ball the last 20 years and it's super sad. The 1991 maxima my buddy had in highschool was so ahead of it's time and quick even by today's standards, and damn near bulletproof.

[@RageUnchained]

I learned to drive on a 91 maxima, and yeah they were bullet proof until the housing around the ECU cracked. Then you’d get random misfires and the trans would slip.

I went to HF and got a moving blanket.... Fold it up however you like, and lay on it... A million times more comfortable, wen you have to kneel or lay on the engine....

[@hugh007]

A thought: squeeze the hose closed behind the broken piece with a long nose vise grip. Then break the plastic with pliers and pull or shake out the pieces. Clear out the hose before removing the vise grips Anything that works is the right way, though. Thanks.

[@APerryNation]

I was thinking the same thing. Im all for destruction but if you break off plastic inside of a tube, there is no way of knowing if you just sent a piece of plastic down into the water pump to mess up the impeller.

[@rusty1187]

Same... Use a hose clamp pliers up stream, crush the brittle plastic, remove pieces

[@spideybuildscars]

That’s how we do it back at Infiniti actually. Take us like 10 minutes to fix it that way

[@jzxtrd337]

just crush them and shake them out, if you're suspicious plastic is still in the system just fill with water to flush out. It should be the only opening in the system and flush out all plastic.

When I saw it was a tow in for over heat, I was pretty sure it was going to have a blown head gasket. That is unfortunate!😟

It really depends on how bad it overheated if they noticed it getting hot and shut off immediately it should be fine if they drove it until it stopped then yes toast

[@bbeckers24]

I knew it was going to be a fun job. I was trying to see if it would have been easier to take the hose off. In the least I was surprised you took the clamps off rather than slide them further on the hose.

[@PastorSutton]

Difficult enough to hold that lower hose, without adding a clamp cutting into the hand. Maybe the upper hose could have kept the clamp. Either way, this was a knee breaking PIA... I am sure.

[@Black3ternity]

For the stuck plastic in the hose: If you have a small hose-pick that fits in there with a U-shaped hook, you could have stuffed it in and pulled it "from behind" - at least that came to mind when I saw that. Edit: For the costs: Depends on why the new radiator was needed. If it was smashed and the broken hose was already there, the shop should have seen that when testdriving it / filling it. If the radiator was replaced "for overheating" the other shop should have seen it. If the radiator was replaced because it was smashed and LATER the hose broke: shit happens - customer has to pay you.

[@nordishkiel5985]

Well, lets review: The bubbling stopped, so a blown gasket is unlikely. The upper and lower hoses were hot, so the thermostat seems to have opened. The waterpump seems active (similar temps on upper and lower hose). Did the fans kick in? Without fan(s), it will overheat while sitting/city driving. As it heats up, it pressurises the system and finds the weakest link.

[@Bryan-Hensley]

I personally think it's not totally purged. I've seen some other comments saying this car has a purge bleeder. It does act like it's still got air in it. This is a tricky one. I'm anxious to see what it is.

[@loneranger4175]

I'm sure Ray will be checking the radiator fluid for exhaust gases using a chemical test kit

[@Bryan-Hensley]

@@loneranger4175 it stopped bubbling. Very unlikely it's the head gasket.

[@lorditsprobingtime6668]

@Nordish Kiel: " The waterpump seems active (similar temps on upper and lower hose)." Actually, to me at least, that suggests the water pump ISN'T working. If it was and the fans were working correctly there'd be a big difference and if they weren't there'd still be a reasonable difference in temps between top and bottom hoses. It doesn't explain all the bubbling but it does suggest no circulation through the radiator. Actually I just realised that could also be a thermostat issue maybe except I'd still expect to see an even bigger difference.

[@shakey2634]

@@lorditsprobingtime6668 Exactly. If you are dissipating zero heat at the radiator, something else is wrong. Ray never commented one way or the other if the fans came on, but I would guess they did or he would have mentioned it. Place your bets, head gasket, water pump, thermostat, blockage or fans? Waiting for part two.

[@MrRunner]

If coolant is disappearing, the quickest, fastest and most accurate method I have found for an analysis is to evaluate the oil. Company called Wear Check will analyse the coolant level in your oil for a very reasonable price. Just send them an oil sample and voila! I had a GM van (3.7 V6) which were notorious for leaking head gaskets (the dreaded Dex Cool ate them). Watched the coolant level weekly and when it took a dive, had the oil analysed. Sure enough. 5ppm of coolant. GM's very kindly replaced the HG, even though it was out of Warranty. I believe shops have access to similar tools. I really wonder why a shop would replace a rad without sourcing the leak, but then, hindsight is a wonderful thing. Love your videos, nice to have someone happy at work.

[@mrfireball91]

Reminds me of something that happened to my 05 Lacrosse, plastic coupling going into side of the engine block blew out and dumped all the coolant while driving down the highway. Wish they would use more metal in cars than plastic, especially for the more important parts like the coolant system.

[@MrTrailerman2]

Yes.. manufacturers need to quit using plastic thermostat housings. I had one split on the highway before.

[@justmemyselfandi5532]

@@MrTrailerman2 Plastic is just fine, Peek for example super strong and expensive to. What they do they they are just making sure your car will fall apart, so that kind of plastic they decide to use.

You can buy cheap stick on carbon monoxide detector patches (Amazon) that change color when exposed to CO. Put one of those stickers on a flat piece of cardboard and put that over the mouth of the funnel. That will tell you if exhaust is getting into the coolant and making those bubbles. Thanks for the videos Ray, they are super educational for me.
