I took off the radiator to take the waterpump off and i misplaced the bolts for it to mount back on, i called autozone they do not have them and rockauto doesnt appear to either.

Does anyone know the size i can use and maybe obtain from Lowes or Home Depot?

 

Go pull a bolt from the bone yard and use that to match. In the future, get a bunch of zipper baggies. Use a sharpie to write what the bolts are for and then drop all of them in a box. It will really speed up reassembly.

 

Q is why did you pull the radiator to change the water pump? That was un necessary. the shroud? OK. but not the radiator/ I do however put a piece of cardboard in between the fan and the radiator to protect it during the water pump change.
