Pineapple Racing Yoohoo Water Pump Belt

[classicauto]

Dual belt alternator pulley setups are a poor alternative because most nominally correct sized belts vary in actual length, making them impossible to tension equally.

Just wanted to address this.

Those running a dual setup and find this problem need to make sure to buy whats known as a match pair of belts. They're cut from the same batch of rubber and thus, are exactly the same size. This is very common for applications like transports that use dual belts, but not so much on these cars so expect that they may need to be ordered in.

I've always just picked and chose from what they have and found two that were very close. They're still going good.

I'll probably do your way from now on though.

Good to know....My Merkur XR4Ti had a dual belt setup from the factory and finding two belts that were the same length and would both tighten up correctly was a pain in the ass
