Why does my car not get warm until you start driving it?

Sincere Morris

Asked by May 18, 2015 at 12:57 PM about the 2004 Chevrolet Impala Base

Question type: General

I can turn my car on to warm up-it can be in the middle on the thermostat and you get in
and it feels like you didn't even have the heat on. Soon as you start driving you'll feel the
air coming out gradually getting Luke warm and then start to build long as your driving.
After a while of course it's got a little warmer but it's like you'll feel/hear it go up/down how
much heat is being pushed out.

That's normal if it gets luke warm. When the engine is idling coolant flow through the heater core is reduced. You get heat from the hot coolant passing through the heater core. The heater core is like a mini radiator. It is possible that the heater core is restricted. But since you get heat while driving, I wouldn't worry about it. A heater core is a big job to replace and costly as well. HTH. -Jim


does the heat get warmer when you put more pressure on the gas? if so it could quite possibly be that your heating module behind the fire wall could be clogged or not getting enough power to give you warm air but instead gives you cold air.
