Belts

[The Baron]

I just picked up two new belts for my Fan Power steering and my Left fan alternator. The ones I bought are rigid, but the old ones are smooth. Does it make a difference, or can I use the rigid ones?

The belts with notches on the inside? I like them better then the solid belt myself, it would seem to help with the belt going around the small alternator pulley and help dissipate some heat.

Notched V-Belts Many studies have shown improved efficiency and life for notched V-belts when compared with standard belts.

A notched belt reduces slip and allows the belt to bend around sheaves with less energy loss. Reduction in motor speed and efficiency occurs when a standard V-belt slips within the groove of the sheave. Efficiency improvements have been found to range from 1% to 3%. Friction between the standard V-belt and sheave generates heat within the belt, resulting in an energy loss and shortened belt life. Notched V-belts can last twice as long as standard v-belts but have shorter lives in abrasive environments where contaminants can become trapped between the belt and the sheave. Notched V-belts may be used with existing V-belt pulleys but typically cost 20-30% more.

Thanks guys

He's right, the belt with 'cogs' or 'notches' are the way to go for improved belt life and reliability. I can dig up some numbers if need be.
