First the water pump was going and we did get it fixed but not before we had an engine overheat, which at the time did not seem like a major overheat since I have been through engine overheats before. However once the water pump and thermostat were replaced the engine did not run properly. It seemed to be bogged down and stressed when running and it also still ran hot. I also got a Check Engine alarm code. The code was for a bad Engine Coolant Temperature Sensor which I replaced myself considering it was right on top. After replacing it and resetting the PCM the engine ran better but the car still ran hot.
What I couldnt figure out was why the coolant would circulate into the engine but not back into the radiator from the engine.
I flushed the radiator thinking their were possible deposits or blockages. I also found a vacuum hose at the rear of the engine that was lose and hissing and replaced the clamp on that as well. After doing that and turning on the engine again white smoke started pouring out the tailpipe. However the white smoke only pours out when driving it not when in park-idle. Thats when I thought blown head gasket.
What I was wondering is could the white smoke be caused by anything other then a blown head gasket? If not then do u know the ballpark price for repairing a blown head gasket on a 96 Maxima with 140,000 miles?
