How To Replace Oil Cooler Assembly [ Chevrolet Cruze/Sonic/Holden Barina 1.8L 1st Gen 2011-16 ] 

Glad it helped!

Hey there, there's probably some air bubbles in the system. All you have to do is make sure the coolant level is good on the reservoir and rev to 2500 RPM for about 5-7min while max heat on. That should get rid of air bubbles and bring the heat back. Make sure you're at operating temperature before starting that procedure and make sure while doing it, the temperature gauge doesn't go too high, it should stay steady.

If it's not blowing warm air into the cabin the heater core may still have air in it. You can usually get it out by running the heat at full blast while the car is on. Do this when the car is warm but not hot. Remove the radiator cap and the overflow cap. Give the car some small taps on the gas to allow the thermostat to open up and bubbles to travel. Then give it a couple of taps on the gas so the bubbles travel out of the system. You will notice that the heat in the car will get hot. During this process you will lose some coolant so pay attention to the overflow tank and fill it as needed. Once you have heat close everything up and top off coolant. Hope this helps. Be blessed.

Make a video

Yes, having done this job, I am extremely sceptical this is possible. Please post up a video to show us all how it's done!! 😂

Thanks for the info! I changed it to include Holden Barina, glad this video was helpful!

Glad to hear that! Good luck man!

I didn't but if you're due for an oil change you can do it during the repair.

Yes I did. If I had a leak I would have changed it but mine was still in good shape.

Thanks glad it helped you ! All part numbers are in the video description.

Coolant isn't cheap lol

Yes you can flex them towards the fan when removing the manifold. Its a tight fit but take your time and find the right angle.

I would replace the oil cooler assembly before blaming the head gasket. If you're leaking oil from the oil cooler, then you can just changed the gaskets and put everything back together. Since you have oil mixing with coolant, the oil cooler assembly is probably cracked and mixing the oil and coolant. I would also check for a water pump leak since they are known to leak from the bottom of the water pump.

si la pieza está rota, entonces el refrigerante se mezclará con el aceite en el cárter de aceite, pero no debe salir humo blanco porque no quema el refrigerante. (translation) if the piece is broken, then coolant will mix with the oil in the oil pan, but no white smoke should happen because its not burning coolant.

This took around 6 hours because of the filming, but the job itself is around 2 hours.

Thank you replying - Have a great day

about 3 hours. This took 6hours because of the filming.

If you need to pull it out, spray some penetrating fluid and wiggle out slowly. If its sitting flush already try to work you way around it. The new pipe o-ring should be easy to put in if you clean the surface first from any rust or debris.

Glad to hear you got it done! You're very welcome for the video , happy to hear that it helped!

I thought you said you was able to replace the part without removing the exhaust manifold? How did you break the manifold bolts if you didn't need to remove it? Just curious bud. I might try your way if it's easier and cheaper

rockauto.com or amzn.to/3sdVCAh

There is a Dorman kit with all the gaskets you need to replace here. If you don't replace the cooling pipes gasket, they might leak if you reuse the old ones. The same kit is on amazon too, just copy paste the part numbers. www.rockauto.com/en/catalog/chevrolet,2011,cruze,1.8l+l4,1446774,engine,oil+cooler+seal,2168

Think it's cheaper to just buy the oil cooler. In my opinion it comes with the gaskets. Not sure haven't checked price just throwing my two cents in

How is it supposed to cool if it's surrounded by heat 🤔

Hey there, you can change just the rubber gasket on the lines, it will be much cheaper in cost, but you would have to get the exact o-rings that fit each cooling line. You will need the parts number for all of the o-rings.

@@OneTrickTech No…I found the gasket great video guide I will be doing this in the near future thanks

Yea you can, the oil leaks come from the gasket on the oil cooler. Did you get a after market part? Is that why the pipes aren't lining up?

I purchase the whole oil cooler assembly and all the cooling pipes so they came with all the gasket already. I have the links for all the cooling pipes in the video description. If you're only changing all the gaskets. Here's a link for all the gasket. There's 1 big gasket for the actual oil cooler. 2 gasket for the assembly (oil filter housing. The gasket goes on each end. And lastly you will need 6 gasket for the cooling pipes. 2 for each pipes. Here's a link for it. Scroll to the last option, tis a Dorman gasket with all you need, but its the only one I found. www.rockauto.com/en/catalog/chevrolet,2011,cruze,1.8l+l4,1446774,engine,oil+cooler+seal,2168

@@OneTrickTech thanks!

Yes of course. There is a lot of coolant going through the oil cooler so its very possible that you get an coolant leak from the o-rings or the coolant pipes

yes, but this is a capless system so it ca bleed itself. When you fill the coolant to the proper level, rev the engine to about 255rpm for 5min and it will get rid of all the air bubbles. when you're done, check the level again and top it off.

@@OneTrickTech Ok so if it doesn't have a bleed plug you just have to fill it and keep filling to right level and rev it for a few min (with the overflow cap off I assume) , but if has the bleed plug is there you can do that as optional? sorry just a bit new to this as you can tell :) Thanks

sure you can do it with the bleed plug if you have one. You keep the cap on to build enough pressure. I also forgot to mention to put the heat on to max so the coolant can circulate to the heater core, while reving at 2.5krpm for 5min.

​@@OneTrickTech ok thanks for confirming that and also with the heat on max for heater core. so basically, it is after draining coolant from the drain plug at the bottom to refill and bleed would be 1 - Open the bleed screw at the top of the radiator which allows air out 2 - Fill the coolant overflow tank with new coolant until it runs out fully from bleed screw 3) Tighten back up the bleed screw 4) Fill coolant level to the cold fill level (about half of the overflow tank) . 5) replace cap fully on overflow tank 6- start car and turn heat up fully and open cabin vents . let car idle for 1-2 minutes let it circulate and get temp up ? 7-run for 5 min at 2.5 rpm 8 check hot air coming from vents 9 take for test drive 10 check coolant level in overflow tank after running top up if needed.

yes almost perfect. On #2 you don't need to fill until it comes out from the bleeder screw, just fill till max and the after the test drive top off to max level again. The bleeder screw is to force air out while you're reving at 2.5krpm for 5min.

no need to but you're due for an oil change you can do it during this repair

As long as your car is not overheating, then yes you can replace the oil cooler assembly because that's where oil ad coolant can mix if the oil cooler is cracked.

Did you do an oil change before starting this job? If yes, I suggest removing the vvt solenoids and cleaning the small screens, they could be dirty. If you did not do an oil change, I suggest doing a fresh oil change with filter. The oil pressure switch is below the oil cooler on the left side near the a/c compressor, check to see if its was damaged during the repair, make sure the wires are intact.

No need to, just like in the video, I removed it without taking it out. Just take a bit of time to find the right angle but it should come out.

@@OneTrickTech Cool !! I just ordered the gaskets and I found the torque specs. You helped me to save a lot of money !!

Tabernacle !! mais tu es Quebecois !! Bonjour de Bretagne !!

hahah oui Bonjour du Quebec. How did you figure that out ?!

@@OneTrickTech Haha !! Because it's written on your main page.

yes

In the video description

According to service manual. The 5 oil cooler housing bolt - 25 Nm (19 lb ft) and the cooling pipes 8 Nm (71 lb in)

Great question and great answer!

yes there's is 3 coolant pipes passing thru the oil cooler. that's what helps to cool the oil, so if you're leaking coolant you should check the coolant pipes mounted on the cooler

No but you can remove it to make more room

No, engine overheating is caused by low coolant, bad coolant flow or bad coolant cooling (radiator fans)

Hey there, so your truck has a oil cooler that's part of the engine. Its mostly like that with engines that have a spin on filter. I've searched oil cooler for your truck as well but they are showing '"the mini radiator" as an external oil cooler that you can install for your car. So to answer your question, you don't have one that you can replace on your truck unless you installed the external one that you've searched up. Hope that helps! Let me know!

its possible. Did you drain your oil and saw coolant mixed with it? Is the oil level higher than usual?

@@OneTrickTech oil looks ok still black. But I got butter under coolant cap. But my oil cooler leak for 100% ...

I'd suggest replacing the oil cooler first, maybe the oil passages has a crack allowing coolant to mix. Top off your coolant and check the level after every drive, you might have just an external coolant leak. I wouldn't blame a bad head gasket just yet.

Overall though, great video you helped me get it done! Now let’s see if it fixes the problem.

The oil cooler replacement is to fix a oil leak. For your case I would check the coolant temperature sensor near the thermostat housing. Could be some wires that are broken or maybe a faulty temperature sensor. There's also a temperature sensor on the left side of the radiator, check that one too.

Ok thanks

Totally agree, these cars require too much repair in my opinion especially when they're under 100k (km). They fall apart after a few years of ownership. GM likes to make stuff as cheap as possible to maximize profits. In the end, we pay the price for all that junk. Oh well. C'est la vie!

@@OneTrickTech Exactly. Mine is paid for and my son will need a car next year. I figure just bite the bullet and do all the repairs and hopefully get a few more miles out of it.

I’ve had many problems out of my 2011 Chevy Cruze but I think I’ve said enough… purchased in 2016 with about 55,000 miles, the trans went out at 88,000 miles. Luckily it was still under a service warranty with the dealership. My driver window motor has went oht twice within 2 years…. Now I’m afraid if I don’t get the engine cooler replaced soon my engine is going to have problems. 😢

Honestly Buy A Toyota Tacoma Or Tundra… Btw I drive a Cruze and it’s sucks

I mean Ford have issues with there cars also...but you said going from a Chevy cruze to a F250. I mean thats different. Now I would change from a cruze to chevy 2500 would make since if you is a chevy fan.

you can remove the radiator fan to make more room

Oil Cooler unit , you can just change all the gaskets

@@OneTrickTech thank you for quick replay. I replaced all the gasket for the thermostat housing and bypass pipe gasket where the thermostat. And noticed coolant water on cat converter and coolant gone . So i had to give try to put coolant seal . Just now I check the coolant level is good and no leaks. Hopefully stay like that otherwise I need to replace all other gasket where the oil coolant unit .

Yes replacing all the gasket is a lot cheaper. I replaced the whole assembly because it was leaking oil from the cooler and not coolant.

amazon mistakes. A few people had that problem already. The part fits 2011-2016 Cruze 1.8L

Thank you so much, great video.

Does the smoke smell like burning oil or coolant.

Oil leaks are not dangerous depending on the size of course. Before you drive just make sure your oil is at a good level, add oil if you need too, and as long as you're not leaking coolant, you will be okay.

@@OneTrickTech So I got an oil change yesterday & leave the 15th, would I be okay? The leak isn’t great. I just wanna make it the 4.5 hours and park it.

@@marzonmedia yea you'll be fine

@@OneTrickTech final question if i am leaking some coolant not much could i just refill on the road and make it?

@@marzonmedia yea as long as you're not overheating you should be okay.

its fine. This one was leaking for months. As long as there is no excessive smoke coming for the engine bay, then you should be ok for 2 weeks.

@@OneTrickTech good. Thank you. Hopefully mine isn't too bad. I worry about snapping the manifold bolts.

yes replace cooler and all the pipes

@@OneTrickTech would coolant flush help with cleaning all that gunk out ? I was gonna replace the coolant reservoir as well.

well you have to flush the coolant anyway when doing this job. Drain the coolant from the radiator first.

@@OneTrickTech okay i sure will, I appreciate you taking the time out your day to reply back. In return I've became a subscriber and will support your future content thank you!

@@ivanchavez6226 you're welcome thanks for the support !

no need to.

You might have some engine damage. You might have a crack in the cylinder head making coolant mixed with oil through the valve cover.

@@OneTrickTech Yeah. That might be. So is it repairable or i need to change the whole engine

will need more diagnosis. could be the cylinder head or the short block.

id say between 600-1000$ depending on parts and the shop.

yes you're right, I didn't think it was going to be that bad but i should have drain it first

the oil pressure switch is beneath the oil cooler (bottom left side). Make sure its not disconnected or damaged. If your oil level is good on the dip stick, then the computer is reading a false oil pressure signal. Could be a faulty oil pressure switch or wiring issue.

@@OneTrickTech It has a fresh oil change. I’ll go ahead and replace the oil pressure switch, thank you.

Were you able to fix this? I am also low oil pressure light on.

@@krishnnarayan6845 this is the link to the video on how I got rid of the oil pressure light

most likely a defective part. I would try to return it and get a replacement one, if it broke during or after installation, its obviously a faulty part.

@@OneTrickTech thanks mate. Just saw you replied. I got it from ebay so probably cant get a refund. But it came with 2 sets of rings and gaskets so Ill try cleaning the original cooler and put it back in.

Which engine do you have?

@@OneTrickTech 1.8

@@braydonh2150 2012 Chevy cruse LS 1.8L says it fit, I tried the LT and LTZ says it doesn't fit because they have the 1.4l turbo engine. As long as you have the same engine like in the video those parts will fit, parts for the 1.4l are completely different.

@@OneTrickTech weird mine has lt badges but it’s definitely a 1.8

@@braydonh2150 its amazon...not the best when it comes to different trims and engines.

You'd have to be a complete numpty to contaminate the filter. No problem putting it back in as long as you're careful!
