AC belt tension (1 Viewer)

[waterbucket1]

I just replaced all belts with toyota parts, and I am having trouble keeping tension on the AC belt? I can tighten it from beneth and after about 100-150 miles it gets slack again. This is my third time that I have had to tighten. Is it common for this belt to stretch this much, or should I be prepared to replace the compressor? It their a lock nut of anything I should know about on the adjustment bolt?

Thanks
Chuck

Did you tighten the lock nut on the idler? See Diagram below

Old thread I know but I'm having trouble getting ac center pully nut to turn without turning the pulley is there a way to stop it or just use brut force

If you are just trying to tension the belt, you shouldn't be trying to turn the nut that holds the AC pulley on - you need to loosen the AC IDLER pulley nut - it's the smaller pulley (below/towards center) from the AC compressor pulley. The idler pulley won't turn when you are turning the nut.

Yeah Sussed it out buddy cheers any tricks to get rounded bolt off it seems the idler pulley under the alternator is seized up and not spinning and the bolt is rounded so as you can imagine the belt is just burning away on the pully
