My water pump began to leak and I have bought a replacement w/gasket and new coolant and now I am preparing to replace the pump. I was told by the salesman at Auto Zone that I should replace the thermostat while I have the pump off - is this necessary? The heater does not work on this S10 Blazer anyway. How do I replace the pump?
