    Water Pump Impellor Size?

    Hi guys, I need to get a new water pump due to the accident. So I called the parts guy I normally deal with and he asked what the size of the impeller was. He said that there were two listings for my car; the pump with the 3 7/8" impeller, and the pump with the 3 3/16" impeller. So my question is which water pump is the proper one for me to use? If they are both usable, which one should I go with? And are there any other differences between the pumps besides the size of the impellers? Give me some input please, because I'm not sure which one I should go with. Thanks in advance.

    never heard em ask that way........all i know is std and heavy duty......the heavy duty will fit, as long as you clean the threads out in the timing cover for the two extra bolts......all the timing covers have the two extra holes

      like the two short bolts in the center of the pump?

        yeah, there are two smaller bolts on the HD pump that aren't on the regular pump, I think they're toward the center/bottom and take a 1/2" wrench instead of the 9/16 the others take, or maybe they take a 9/16 instead of the 5/8. Whatever it is, I've been trying to block out memories of excessive water pump replacements. I have heard them ask iron or aluminum pump before, iron is usually the HD one. Never been asked about an impeller size though.

          Well apparantly then, I had the HD pump. Surprisingly, it was cheaper than the other pump I have most of the motor back together, minus the water pump pulley, fan, and alternator. I used a pressure tester to check for leaks. Everything checked out good. Thanks Scott, Thain. I appreciate your help greatly!
