I have a 91 RS TBI with a serpentine belt and I was wondering what belt size will fit with out the Smog or A.I.R pump pulley, i still have the AC, water pump, alternator, power steering, and crank pulley. What size belt would I need just w/o the A.I.R Smog pulley?

 

There's a tech article off the main page - it states a size but that size didn't work for me when I did mine - just measure with a string then go to parts store and get that size.

 

thanks i saw the 96.8 size belt is what their telling me do you know what size you used? and is that with or without out the delete pulley?

 

It's been 2 cars ago, so I don't remember. But the .8 I never understood, as they come in even inch sizes and 1/2 inch sizes, so you'd either have to get a 96.0 or a 96.5 for example. But if you buy one and it doesn't fit, they'll take them back for exchange - or do the string trick.

 

alright ill try the belt or belts (if I have to) and will try and let you know my results it i wish i understood how to jus take off the whole pump and disable the whole AIR system ive read threads about it but i didnt fully understand what they were talking about but im sure when i get down in there everything will be fully understood or will make sence then thanks again

Just take it off. Just take the pump off the bracket, and remove the hard lines from the pump, then remove the plastic box. Then, you go get threaded plugs from any hardware store to replace the check valves on top of the exhaust manifolds, and plug the tube from the cat converter, and you're done.
