oil filter wrench
 

Can someone tell me where to buy an oil filter cap wrench. TIA

I think you just use a 36mm socket...

Auto zone or O'reilly's has them.

:iagree: ...and, Sears or any decent auto parts joint. And, 36 is
the deal. Some places even have a 36mm plastic job instead
of the 1/4 lb metal socket.

+1. I purchased mine from Sears.

i have 2 of it .you can have 1 if you like.

look for 36mm GM axle socket - cheapest at autozone $6ish ...

AutoZone has them for $16.99, but you can also "borrow" one from them through their loaner program.
