Re: Low Coolant and Heat

Usually there is a very thin line where the heat doesn't work as well. Most of the time it works just fine until it doesn't work at all. That is because the coolant isn't circulating as fast because the water pump has to wait for water to come through the radiator/heater core before it can pump it through the engine. Normally there is plenty waiting in the radiator. When the coolant is flowing through the heater core slower, the incoming air is able to take more heat out of the coolant than is available.
