The oil cooler transfers excess heat away from engine oil, keeping its temperature and viscosity in a safe operating range, especially under heavy load or in hot climates.
If you notice any of the following, the part likely needs replacement:
Oil temperature warning light or gauge reading high
Oil leak visible on the cooler itself
Engine running hotter than normal under load
Installation information
Requires draining the oil before removal, and always fitting new seals at the mounting connections.
Frequently asked questions
No, it’s more common on performance, turbocharged, or heavy-duty vehicles where the engine generates more heat than a standard cooler-less setup can dissipate.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
