Is the water pump upgrade that SS Diesel and the other companies sell, just a water pump from a 97' or newer?? Cause if so, I can get one for a 97 thats 42$ from Airtex or 70$ from Acdelco. Does not seem like a bad deal. Any input???
Some 1996 trucks have the water pump,dual thermostat crossover. The change over was running change & I don't know the date or VIn it occured at. Have you checked to see if you have 2 thermostats. ? If you don't have replace all the parts. Personally I would get the 1999 parts with the composite fan blade,matching fan clutch & specific 1999/2000 waterpump. Any year dual T stat crossover will work & don't try to run single t stat with 130 GPM pump.GM claims freeze plugs can blow after just changing to the 130 GPM pump.
