Default Mezeire belt question

I've got a mezeire street pump. Do I have to run a belt on it? All I am going to run in this application is an alternator so I really don't need much of a serpentine. I just don't know if that idler does anything really.

To give a less vague answer, all the idler pulley does is take up slack in the belt. They're mainly used in serpentine type systems where the belt is quite long and, thus, needs a secondary tension mechanism.

You could probably find a belt small enough to just run around the alternator and crank pulleys, but without an adjustable tensioner it's gonna be a bitch to get it on and off....


Check ls1howto.com, I think there's a writeup that explains how he routed the belts....?

You don't have to run the belt over it, as said, it's just an idler.

I believe there's a way to run just the alternator by putting the tensioner where the stock idler pulley is or something. I've seen it, but it was quite a while back.

Yeah I've got a tensioner down by the alternator, which is low drivers side, that I can use to snug that belt. I just didn't know if the big pully on the pump served any cooling function to the pump motor or anything.

Thanks
