Yesterday, while changing out my radiator, I accidentially sheared off three bolts from the rotating assembley. What thread pitch and length are the pulley bolts? Anyone have a clue?

I'm pretty sure it's like a 1.5 pitch.

How sure is sure?

its a common metric thread, take the one you didnt shear off to the hardware store to match it up, and dont overtighten them!

The funny (Well, not really funny...) thing was that they melted off while backing them out. After the bolt was broken loose from the pulley. Three at a time = Annoyance. Do you know how they rate the tensile strength for fasteners? I think I need some bolts that have a little less ability to break. (This is on a SA22C, so the bolts are 25 years old)

I over tightened one and had to go to the autowreckers to find it

ya i broke a bolt in the water housing 2 and it was stuck in there good adn we got it out but ended up braking the hole corner of the water housing so i had to buy a new one of "Hades"

iam never gunna make these mistakes again, Iam gunna learn to use a torque wrench
