I'm looking at a car for sale and and the A/C belt is off of it. I do not see a belt tensioner for the A/C belt and wondering where it may be? Maybe that is the reason the belt is off and not a compressor problem?

Thanks for any help

Or does the compressor pivot and this is how you tighten the belts on these?

 

which engine?
on my 550i, there is no tensioner, and the compressor doesnt move. the belt is just streched on to the pulleys.

 

Thanks for responding.

It is a 545,

although it could be possible I don't see how, belts don't stretch that much.

How would one install it?

 

thats what i thought also. the belt is kinda small and gives a little.

That is so funny.

I was a mechanic in a past life at a dealer for15 or so years until I broke my back. When I originally went to school they frown on bumping belts on, and doing it on a serpentine belt was like

 

It appears that this belt is a special belt made to stretch for systems designed to use them. Thankfully I bought one from the dealer rather than a non stretchable serpentine replacement of the same size at the local Kragen auto parts.

It is about impossible to install without the tool.

I was quoted $85-$120 for the tool at the dealer while my searches on the net, got me nothing.



Thankfully I can still use my brain, I made my own tool in less than 15 minutes.
