What size socket is needed for the oil pan drain plug in a 1997 Chevy Cavalier?

It's metric for sure and what ever you do, don't use a open end adjustible Cresent wrench, because you will round it off, when you go under take a 13,14,15 with you and don't forget to take the filter and little oil with you to wet the gasket and a rag :(

Oil Pan Drain Plug Size

The 2.2L Ecotecs that are on the Cavaliers take the cartridge type filters, not the spin-ons. So, to remove the cap, you need a 32-mm socket. I got mine at the local Murray's Discount Auto, specifically for the 2.2L Ecotec engine according to the package. Worked like a charm on my Cobalt to get the oil cap off, The filter will be attached to the bottom of the cap, which can be pried off. Put the new filter on, then reattach the cap, no more than 1/4 turn with the socket wrench after hand-tighten. Be sure to let the oil drain out of the filter into the cannister before you remove it completely.

Hey TWISTED The correct ans, is a13mm or a15mm wrench or socket! (pending on motor size) Your better off at a quick change place! 20$ It will cost you 15$ and get rid of the oil. Be smart! MIKE

i own a repair shop,and i think this one uses a 15 mm, socket on it,i do these all the time but sometimes remembering a size is hard to do,,but i think this is right,,good luck i hope this help,s,,it may be a 13 mm also i remember a few that were smaller.

It is somewhere between a 13 & 15 mm, but my first guess would be 15, if it has the original factory plug in it.

3/4 i believe, it depends on what size your oil pan is though

As long as you have a basic set of tools it should be in there. If you do not then it may be to tuff of a job for you to tackle. It is very easy to do but if you mess up your car could detonate.

The last one I did was 15mm. I have also seen them with 13mm

probably a 18 mm.
