My 1989 F150 302 AC compressor is history. Removed it and I wanted to know do I need to install a idler pulley in place of the AC comp. or can I just use a smaller serpentene belt? Does anyone sell a kit to replace the AC compressor with a plain old pully?

 

You'd have to look at where the belt will lie if it runs straight - it might rub something & wear out instantly. I'd advise just unplugging the clutch & leaving the compressor attached to the engine. It's gotta be the cheapest idler kit you'll find.

 

> or can I just use a smaller serpentene belt?

You should be able to use it without the A/C. I would hit a junkyard (or used car lot) and find one without A/C and look at the decal under the hood for the proper routing. If at a junkyard, I would take the decal.

Then just order the "without A/C" belt from a parts store. If by chance that does not fit correctly, buy one of those emergency belts that snap/hook together. Then remove and measure it.

Make sure the tensioner is in good shape.

 

ya unhook the compressor. if the clutch is locked pull it out. or then again instead of buying that belt take a pieces of thin rope and run through your pullys minus the a/c and messure its lenth. and your done....

 

Thanks!:-)

 

[updated:LAST EDITED ON 19-Dec-02 AT 00:16 AM (EST)]Thanks for all the suggestions, I ended up just eliminating the comp.altogether and going with a smaller belt. It took a couple of trips to auto parts store but a shorter belt works fine!

 

What belt was it? I am removing my A/C from my 1990 F-150 and will probably try to use a new belt if I can. If you tell me what size your belt was I may have a a good start on it.

BTW: I have a 351W EFI is your engine the same size? or are you running a 302?
