Hi there,

The oil cooler heat exchanger is normally the cause for coolant in the oil.

And vice versa.


Customer: replied 1 year ago.
2009 had this exchanger? I am not sure about this model
Expert:  Gary replied 1 year ago.

Can you verify this with your local mechanic please?

I'm not 100%, but I've seen this on many vehicles.
