My car was running hot so i change the radiator because i had a crack thought that would work. Well it didnt work. Changed the thermostat. Well it didnt work. Now i want to change the water pump.


Asked by Jul 24, 2014 at 07:30 AM about the 1997 Ford Expedition 4 Dr XLT SUV

Question type: Maintenance & Repair

I realized that when the car is parked
heavy smoke is coming from the
muffler. But when it is in drive no
smoke. So do you think my water
pump is the issue for my car running
hot still and do think that will help
with the smoke too.

What color is the smoke? Black smoke= unburned fuel. White smoke = coolant. White smoke is a problem. A big problem.


Your description sounds like a blown head gasket or warped head. Is there any kind of milky substance under the oil filler cap? If so... TRUBLE. pull head(s) to find the problem.
