Chevy Water Pump Leak
Water Pump Leak Repair I have a problem with a water pump leak. I have replaced the original with a new pump, but I still have a leak I suspect around the gasket between the waterpump and the engine block. Any suggestions? I was very careful to clean the surfaces and evenly tighten the six bolts in a rotation first finger tight, then to 11 ft-lb, and finally to 22 ft-lb. Is 22 ft-lb the right final torque or do I need to re-torque after the engine has been through a couple of temperature cycles? Solution: I would check the intake gasket for leaking and running down,looking like its the waterpump, as far as I can tell you are doing everything right ,if need be I would put a pressure tester on the cooling system and pump it to 20 lbs and looking very closely at the intake. all I can suggest is to put a little sealant on the bolts,11ft lbs the first pass and 22 ft lbs final pass is the correct specs.no I wouldnt torque it to 28 ft lbs as you are asking ,.let me ask this...
