maddmann313 Posted January 13, 2011 Share Posted January 13, 2011 What kind of belt do I get to go around the ac pump? I have a 72 with a 350. Also If I get a new ac pump before I use it what should I check?? the car has sat with out ac for a while! Quote Link to comment Share on other sites More sharing options...
wallaby Posted January 13, 2011 Share Posted January 13, 2011 I should have checked "O'RLY" auto parts for ya...but I checked Autozone. They show a #15549 belt (15/32 wide, 54.9" long). They also show a 15545 belt (54.5" long). I'm not sure which is correct, but they are pretty close to the same size. When you install your new belt, put it on the AC pulley first and then put it over the crank pulley. Sometimes you have to lay the belt behind the crank pulley to do this. Because the AC pulley is so deep, it's hard to stretch the belt around it if it's already in position on the crank pulley. Quote Link to comment Share on other sites More sharing options...

maddmann313 Posted January 13, 2011 Author Share Posted January 13, 2011 well before I got the car the ac was already locked up and there was a box of tranny fluid in and box with a 15545 belt so that must be what it was going to be used for!
