Don't this beat all......I put my 14 year old el-cheapo rebuilt Carquest water pump back on the car and it hasn't been hit 200 degrees or boiled the water since. I've got a 170 dollar Edelbrock that ain't worth throwing in a gully. The passenger head was around 40 degrees hotter than the driver's side with the Edelbrock pump and with the stock pump they are the same temperature. I just drove the crap out of it for almost two hours and it never hit 200. I let it idle for a pretty good while and the cooling fan cycled on and off perfectly with no rise in temperature. What should I do now?
