1996 Plymouth Voyager 6 cyl Front Wheel Drive Automatic 155000 miles
I am getting intermittent heat from my van.
When I am idling, the heat is cool to slightly warm but when I start driving, the heat works fine. When I slow down or come to a stop, the heat goes back to slightly warm again. The coolant level is fine and the car is not overheating. Somebody suggested the water pump. What do you think?
