Hey everybody:

Do any of you have a reference that gives the engine coolant drain plug torque? (at the bottom of the intermediate side housing)

I changed my coolant last weekend and used a copper crush washer because the dealer didn't have the OE ones in stock, and noticed a little weepage around the bolt head. (I hadn't driven the car yet so no harm done)

Anyway, I did put the proper crush washer in there now; I think the copper doesn't crush as easily, and maybe I didn't get the bolt tight enough. So, just to be safe...

Thanks!

I picked up a new 2010 RX8 GT engine coolant drain bolt crush washer (gasket) from Mazda and did talk to and check the torque in the rotary repair manual (not listed in our online version). The torque specs are 12-15 ft-lbs. The crush washer part number for reference is 9956-41-000 131
