 OT: How tight is too tight on the belts?



Just curious, I replaced the belts, valve cover gasket, and hoses and such on the beater, and it squeaks...

No problem, just tighten the tensioner. A 5 minute job.

Done that a couple times now, and it fixes it for a week or so.

But now its slower to start up, I guess from the belts being too tight?

Factory belts from dealership.

No squeeks.

Recomendations?

Serpentine or V-groove belts? I'm gonna guess V-belt (serpentines almost always have spring loaded tensioners).

On the longest span between pulleys, you should be able to deflect the belt (pushing inward) about a half inch (1/2"). If you can't do that, it's too tight.

Just to add an additional comment, if the belts are too tight, the bearings in the pulleys will wear prematurely due to too much side load on them.
