Does anyone have any idea what the o-ring size is for the oil cooler to oil filter stand on a 2002 GC Sport? I have searched high and low and cannot find a size.

Thanks.

 

I have two Mopar numbers, one 4781166AC that is for the adaptor that is the gasket to the engine block. The other is called a gasket not an o-ring, that number is Mopar 5093807AA.

 

Thanks MT. It is in fact an o-ring that sits between the cooler and the oil filter adapter. I was able to find one at the local parts shop that was a "match", got it installed, and no more leaks! Unfortunately, I still haven't found an actual size for the o-ring. Oddly enough, rockauto lists one with the size for mid to late 90s GCs, but nothing for 2000+ models.


Thanks again.
