Engine Oil Cooler Problems in a Modern Chrysler 3.6L V6
February 20, 2026
If you drive a vehicle with the Chrysler 3.6L Pentastar V6 engine, your engine has a small but very important part called the engine oil cooler. This part helps control oil temperature so your engine can run smoothly and last longer.
At Jim Brangham Auto Repair in Cathedral City, CA, we see oil cooler problems on these engines more often than you might think. Here’s what you need to know.
What Does the Engine Oil Cooler Do?
Your engine oil does more than just lubricate moving parts. It also helps carry heat away from the engine. As your engine runs, oil temperatures rise. The oil cooler helps bring those temperatures back down so the engine can stay protected.
On many modern Chrysler 3.6L V6 engines, the oil cooler is built into a plastic housing assembly that sits in the center of the engine. This design helps the engine warm up quickly and run efficiently. But over time, constant heat can cause the plastic housing to crack or warp.
Common Signs of Oil Cooler Failure
When the oil cooler housing begins to fail, you may notice:
- Oil leaking under the vehicle
- Oil collecting on top of the engine
- A burning oil smell
- Low oil levels between services
- Check engine light turning on
Sometimes the leak runs down the back of the engine and looks like a rear main seal leak. Many times, though, the oil cooler assembly is the real cause.
Why This Repair Is So Important
If the oil cooler leaks and the issue is ignored, oil levels can drop too low. Low oil can lead to overheating, low oil pressure, and serious engine damage. In severe cases, oil and coolant can even mix.
Catching this problem early can save you thousands of dollars and prevent major engine repairs.
Here in Cathedral City and throughout the Coachella Valley, extreme desert heat puts extra stress on engine components. That makes it even more important to address oil leaks quickly.
