How many grooves on pulleys for A/C & P/S ?
« on: January 16, 2007 - 09:25:05 AM »
I'm missing the pullys to put the A/C back on my '70 Challenger 383 and need to find the right ones but I'm not sure what that is. can anyone tell me how many grooves are on the crank and water pump pulleys for a car with A/C and P/S ? probably better ask about the alternator and P/S pump while I'm at it too.  thanks

On mine the crank had 4 grooves, the water pump had 1 groove, the alternator had 2 grooves, and there was an idler pulley as well.

Thanks, so the A/C belt doesn't go around the water pump?  I better see if I can find a diagram of an A/C , P/S car belt routing so I get things right.

Thanks a bunch that makes sense now, looks like the water pump pulley has a lot  less set back than the non A/C one I have now. OK now if I can just find a set.
