Have seen loose bolts cause oil to leak(no thread lock) I guess it could leak and mix with coolant.

 

Heat exchangers of all kinds are known to start leaking. When installing a solar water heating system that must be filled with antifreeze, the heat exchanger is required (at least in the USA) to be the more expensive and less efficient "air gap" type. When an air gap heat exchanger leaks the leaking fluid goes into the air rather than into the other fluid circuit.

Anyway, I do not recollect hearing any other reports of such failures.

 

This is a very common problem on these cars, even newer cars. I just picked up my car today from the dealer for same issue. They have 8 cars with the same issue. Alfa is supposed to be coming out with an updated design cooler.

 

Este es un problema muy común en estos coches, incluso en los coches más nuevos. Acabo de recoger mi auto hoy del concesionario por el mismo problema. Tienen 8 coches con el mismo problema. Se supone que Alfa saldrá con un enfriador de diseño actualizado.

How many miles in your case?

 

Thank you all for the heads up on this issue. I will check and re-torque the bolts on my oil cooler to factory spec every so often or when I perform an oil change.

 

Where did the crack occur on the oil cooler?

 

It does occur, however not that often. I've done probably five motors due to this kind of failure since the Giulia came on market. It usually requires replacement of all engine coolant hoses, thermostat/triple valve, some hard lines and the heater core in the dash to fully removed the oil from the system. Also, usually the cars overheat with a lack of coolant flow, so the engine is usually damaged(if you have a stored coolant temperature sensor rationality code, you could be in trouble, as it indicates an overheat).

Back when working at an independent shop, I used to do quite a few head jobs on old I6 Mercedes cars with oil in the cooling systems... usually what I'd do is fill the cooling system up with a strong degreaser and run the car up to operating temperature and power flush the system. I'd do this around five times. It's a messy, terrible job, but might save you a lot of money on parts.

 

My dealership has seen a "few" of these heat exchange failures.

 

Hi everyone! I own a 2017 2.0 veloce(TI) 98000kms(61000miles approx). I have had the problem of a cracked oil cooler, oil entering the refrigerant circuit View attachment 143669 View attachment 143670 Damaged oil cooler: View attachment 143671 View attachment 143672 The problem has already been solved with the necessary cleaning and change of antifreeze. Has anyone else had the same problem? it was quite a little expensive repair! It was in the workshop for a week and I really wanted to drive it again!!

Where was the oil cooler cracked and did you change the whole oil cooler or just the gasket?

 

Oil cooler complete, due to internal crack. I recommend keeping an eye on the antifreeze. If the problem is not seen in time it would cause a much bigger problem of overheating.

 

i got a 2021 alfa giulia and i just found out this right now that i had the same problem if you dont mind me asking how much did you end up paying.

 

@angelo626alfa. Welcome to the forum. Did you purchase your Alfa new? What model is it? Please tell us more about yourself.

 

yeah i bought it new back in 2021. its just a Giulia but the same thing happen to my car and was wondering what you guys fixed so i can order the part for it. yesterday I took out about half qt of oil out with a painting roll. just stuck it in the hole and with the glove on was squeezing the oil out. to see if its shooting oil out alot

 

You should be under warranty, unless you're over on miles. 4yr/50k

 

It could be the engine oil heat exchange contraption. Where are you located?

 

Knowing how little variance the oil level system has, I would think low oil icon and warning would come on rather quickly after cooler fails.
Anyone know where on the engine this cooler is located??

 

^^ Here is a repair video for the oil cooler. It is looks like PITA repair, however it looks like the mechanic in the video did more that was necessary to remove the cooler(AC lines).

 

Omfg looks like total pita plus!!
No wonder they fail. The cat cooks it to death!!
Thanks
Hope mine survives!!

I am thinking the same thing. Why would an engine oil cooler be place near the hottest parts on an engine such as the turbo and exhaust?

That is one repair that I will let my extended warranty handle if possible.

At least put a heat sheild there😮😳😂

 

Help guys,

internal oil cooler failure on my 2020 alfa romeo guilia. Dealership wants to rebuild the engine and replacement the entire coolant system
