bolt size
After installing electric fans and removing my flex fan I did not have any bolts the right size or short enuf to bolt the pully on to the water pump. So I had to bolt the spacer back on to hold the pulley on but looks nasty. So anyway what size and lenght bolt do I need?
Thanks

Re: bolt size
It's gonna be a fine thread bolt (I think it's a 1/4" bolt), mine are about 1/2" long. You should be able to take you spacer bolts and just get a shorter version right?

Re: bolt size
Should be 1/4-20 (coarse thread) X 3/8 or 1/2 long. Always use grade 5 or grade 8 for automotive applications. Grade 5 is a medium strength, grade 8 high strength. Most hardware store grade 8 bolts have a cadmium plate finish, gold colored, which is better than the zinc plate, silver color on grade 5. Takes longer for the cadmium plate to start rusting.

Re: bolt size
I wasn't sure on the diameter, but I know for a fact all of mine are fine thread.
