I put on an electric fan and the bolts that used to hold the pulley to the hub are way to long what size bolt should i get...I need to know what the thread size is for the water pump hub...cuz I got some new bolts and they seem to only thread on for a turn and stop and get real hard to turn
I dont know myself, but here is perhaps something else that would work. Hit the parts store - have them grab a new pump. Then use their selection of nuts/bolts to decide the thread on the pump.
Not what you wanted, but perhaps better than nothing. I wonder too if you called a resto house, if they could look it up and tell ya.
Good luck.
Right after posting that I found it on the web. Well I think I found it, 5/16-24 thread. I pulled one out of the bin at work and will see if it fits when I get home. If it does I will go buy the right ones. I figured doing a search might save a few trips to the parts store. Thanks
