Heater problem
1997 GMC C1500 6 cyl Two Wheel Drive Automatic
I recently replace the water pump the thermostat on my truck the pump was leaking and the heater works but was not giving out heat. after replacing the parts I had the engine flushed and new coolant installed. I tested the heater and it would warn up but then start to cool down it will not stay warn.
