Why does my car have no heat at idle?
Why does my car have no heat at idle?
No heat or hot air during idle is the result of air gap in the heater core. Open hood, driver side fire wall you will the see the heater core rubber hoses.
What should I do if my impala has no heat?
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. Raise the rubber portion of the heater core hose as high as it will go with it still attached at the heater core. Using a funnel, add coolant until the hose is full. 5.
Why does my Chevy Impala blow cold air at idle?
I have 2006 impala that randomly will blow cold air at idle. Sometimes if I stop at redlight the heater will blow cold air. 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.
What to do about poor heat at idle?
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.
Why does my car heater get hotter when I drive?
When your vehicle is in motion and driving down the road, then engine coolant temperature tends to get hotter on the engine before it gets to the radiator, so the heater will naturally heat up more when driving around.
Where is the heat located in a car?
In it’s most basic sense, the heater core is what causes the “heat” in your car. The heater core has engine coolant running through it, and it’s usually located in the dash. As the coolant heats up, the “heat” becomes available (or noticeable) when selected, in the passenger compartment.
What to do if your car has no heat at idle?
With the cabin heat turned on and engine at operating temperature. Idle for ten minutes before shutting off the engine. Locate the heater core hoses, they’re fitted on the fire wall behind the engine. Grab both hoses, both should be roughly equally warm, if not, the heater core is blocked.
Why does my car heater blow cold during idle?
On really cold days/nights, they all tended to lose coolant temp idling under zero load with the fan blowing on the heater core. Thanks. I bled the coolant system as much as possible, was able to get some air out and top off the system. It warms up quick and stays at a steady temp, but heat still blows cool (maybe a little better…).
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.
What to do when your car heater blows cold?
Allow the engine to idle until all the air is purged from the cooling system, and nothing but coolant comes out. Remove the screwdriver, and reinstall the hose clamp. Heater blows cold while in idle but hot while running. How cold?
