Quick question for you guys. I am going to change the Idler pulley and the tensioner/pulley. How do I tell if mine is the Hydraulic or Spring model?
thanks
no they are different tensioners.The tensioners are mechanical on my (01 325i Auto) I believe the upper and lower one are the same correct?
No, what Mango tought (I think) was that there was one tensoner for A/C and one tensioner for alternator with their respective pullies, plus the idler pulley - total of three (3) pullies....
Edit: Not sure what Mango means by "one of each". You'll have one or the other.
Edit 2: nvm, he's talking about the idler and the tensioner.. all idle pulleys are the same.
both of mine were mechanical and they were stock.no they are different tensioners.
One pulley for the a/c belt, one pulley for the alternator belt, and one deflector pulley. Total of three. It's stickied, people. Come on.Presuming the OP is now confused...since now I am...
You have two tensioner devices, each with a pulley attached. Each device has a different pulley that fits, so you need to know what your devices are before you can replace their pulleys.
You may have one of each or two of the same kind...we don't know what you have. Mango suggested you get new tensioners themselves, which you could do, but they seem to last a real long time so might not be necessary. The pulleys on them, though, do wear out and should be replaced.
Also, when we refer to 'three pulleys' here, we mean the two tensioner pulleys and the one idler. Idler is the same always.
But, we do also have pulleys that are replaceable on the WP, PS pump, and Alt--these pulleys are just that--they don't have integral bearings in them.
I hope I haven't made this more confusing! :lmao:
