I need to replace all of my V Belts. Where is the best place to by the good ones? Stealership or ICH? or others.

I have had good luck with the Daco diesel rated belts i got at Advance auto.

Gates, available independant or as Napa's captive brand. Also Goodyear.

Gates makes a non strecth/non cog alternator belt that's used in the ambulance packages #5723. The other belts are:

P/S 9570
AC 9630
Vacuum Pump 7320
Alternator 5723

If you have excessive alternator belt flop, it's probably due to a bent water pump pulley. If the vehicle has ever lost a belt, it probably wrapped around the water pump pulley and bent the pulley. f you continue to lose belts, replace the pulley with a new one from Ford.

Couple people at this end swear by Motorcraft belts.

BTW: Thanks for the heads up on the bent pulley.

For a number of yers I went through Alt belts every few months, even with the idler. Changed the pulley and now don't need to change the belts.
