Re: which pulleys do I need?

Re: which pulleys do I need?
The power steering pump is driven directly off the crank with its own belt. If I remember correctly, both the alternator and A/C belts also drive the water pump. There is one V groove in the crankshaft pulley that does not get used. Hope this helps.

Re: which pulleys do I need?
That is correct. One short belt going around crank and directly to PS pump. One belt from crank around WP and Alt. One belt around crank WP and AC if you have it.
So crank pulley needs 3 grooves if you have AC , WP needs 2 grooves, PS is 1 groove. |
