Heater blows cold when stopped
The heater get very hot driving but when I come to a stop light of slow down, it gets cooler and almost cold when stopped. Once I take off, it does get hot again... any suggestions?
Thanks for your help!
Thermostat might be going bad
Sounds like the impeller on the water pump is worn. Time for a new one.
check your water. it might be low. if not then it's water pump.
