you need to take it to your local dealer and raise a big fuss because this is a known problem and if you yell loud enough you should be able to get this fixed under warranty.

Oil cooler leak


I do not really see the problem here. If you found the leak then it is pretty easy to fix. I do not know if the oil cooler seal is available separately. Most of the time the Mazda dealer only sells the seal with the oil cooler and that is pretty expensive.

How to replace the 2 gaskets on the oil cooler on 2.3 leter 2007 Mazda cx7?


Contact your Mazda dealership's Parts-Dept. w/ this Part-Number: LF8X-14-702 for the gasket, or place an online-order for twice the cost as my local-dealership:
http://www.amazon.com/MAZDA-CX-7-MIATA-COOLER-GASKET/dp/B00DQYG9D4/ref=pd_sim_sbs_auto_1/190-6912148-0373061

I just helped a friends save > $500 w/ this Mazda info. Ebay has options as well if you want to pay 1/4-1/3 of dealer-prices for the oil-cooler itself, which - as all probably know now - includes the $5 o-ring gasket.

Best wishes,
Nick
