91 626 oil filter

Im replacing the oil filter on the 626. Does anyone know what size oil filter wrench i need? I know they come in the small and the big size but dont know which one to use. Also the problem i still have with the screeching shouldnt even be doing that, I was looking over my records and i replaced the alternator and the belt, so it shouldnt be doing that, and i replaced it like not even 4 months ago, HELP!!!!! Are the alternator bearings seperate from the main alternator, or was it a bad alternator that was put in? Any feedback would be appreciated, Thanks

I have the automatic 2.2 liter 4 cylinder non turbo

If you have the 2.2 it's easier to use the cap (sml) due to space limitations. You can find it at Wal-Mart or any auto parts store for 3 to 5 bucks...mojo

the squeel could be coming from the belt itself try replacing that and see if the squeeling goes away.
