Okay. So while I was at work my dad decided to replace/fix my clutch fan. At this point your probably reading this thinking oh no. Because we both know (unlike my dad) that the waterpump and clutch fan are one unit. Well let me just tell you the damage he left me to deal with. A bent pully, a water pump bolt broken in half stuck in the block, and 2 missing waterpump bolts. The funny part is, he told me he fixed it, I start it, and water sprays out like a sprinkler. Lmao someone help me. I need to know the sizes of the bolts that hold the water pump it so I can buy new ones somewhere. :cry:

clutched fan? xD that is rough... I'm so glad my father isn't mechanically inclined enough to even think about touching my rigs.. The down side to that is I'm always fixing his junk. >.<: my fan clutch is siezed up as well but I couldn't tell you the thread count/pitch whatever or the length as I need to keep it together just alittle longer lol. I'll see what I can find unless someone here beats me to it.

The water pump uses two different sizes of bolts. M8 X 1.25 and M12 X 1.25. Can't remember the lengths but put a screw driver in the hole to get the length.
