I discovered a substantial quantity of oil in my coolant reservoir. I extracted it and substituted some coolant.

I aim to ascertain the source of the leak, and many have suggested that it is an issue with the oil cooler. The oil cooler is located on the front driver's side beneath the bumper. This system is fan-assisted and features two connected cooler pipes. I do not observe any coolant lines linked to the oil cooler.


Where are the oil and coolant tightly interconnected?

Thank you.

The fluid may be gearbox fluid since the cooler is integrated within the radiator. Alternatively, conduct a leak-down test, as the head gasket may have failed.

What is the current year?

2004

undoubtedly engine oil

It is time for a leak-down test.
