Why does my car not have heat when idling?
Why does my car not have heat when idling?
Two things come to mind, defective or wrong thermostat or low coolant level. The engine makes very little heat when idling, and if the thermostat does not close, the engine coolant temperature may drop low enough that you’ll get no heat from the heater core.
Why is my Chevy Impala no heat at idle?
If I get the engine above idle by reving the engine to about 1K rpm it starts to blow warm again. The temp gauge remains at the normal spot on the gauge. The radiator and expansion tank are at the correct levels. It turns out the problem is pretty common with 3.5L Impalas. For some reason these engines lose coolant.
Is the 3.9L engine bad on an Impala?
The mechanic that would be doing the swap says he was very surprised by this and had never seen this happen with the 3.9L. Especially since this car has only 58000 on it. I just wanted to share my sad story and maybe anyone else on here who may have had a similar problem.
What’s the normal temp in a Chevy Impala?
The factory gauge settles in at “normal” for a 160-200 degree range (normal temp is 185). At 160 the car barely makes any heat in the cabin, at 185 it’s got decent heat, and at 200 it can light your feet on fire. 🙂
What to do if your car has no heat at idle?
First check your coolant levels in your radiator and reservoir tank. Poor heat at idle, however, if the engine RPMs are raised the concern no longer occurs. 1. With the engine cooled off, remove the coolant pressure cap. 2. Remove upper heater core hose from the metal pipe on the engine. 3. Add coolant to the metal pipe, until full. 4.

How does the heater work on a Chevy Impala?
At the simplest level possible, the heater works by passing hot coolant from the engine into a tiny radiator called the heater core. At this point, the blower motor blows air across the it and the newly heated air blows on to the driver and passengers. If the heater has stopped working in your Impala, this process has failed in one way or another.
