how normal and often are their problems with the oil cooling system aside from the other cooling system?

 

Well the oil cooling on the FC and later models provides about 30% of the cooling of the motor, but over all there are fewer things that need servicing or updating and for the most part Mazda overbuilt the oil cooling on the FC and the FD's with dual coolers.

Why do you ask? Are you having cooling issues?

 

nah, just wondering lol.
Good info for future use ya know?
thanks much for the reply
