How does a car heater work to cool the engine?

Assuming it’s a water-cooled engine, yes… at least a little. When you use the heater, coolant (aka antifreeze) is circulated from the engine to the heater core. A fan blows air over the core, and thus extracts heat from the coolant.

Is it good to run heater to keep engine cool?

That little heater core is not going to keep your car engine cool for very long. Routinely running the heater to “help cool your engine” is a waste of time and effort… it’s really not going to do that much beyond what the radiator is already doing. Get paid to install solar + battery for no cost at install.

When does the car heater blow cold air?

I have 2006 VW beetle with the 2.5L engine. Once the engine has warmed to operating temperature, and I am driving it around, the heater works great. As soon as I stop at a red light, or am idling for any length of time the air coming out of the vents begins to lose temperature until it blows cool air.

Why is my heater not working in my car?

The other possibility is that the thermostat may not be allowing the engine to reach a normal operating temperature and since the engine’s warm coolant is the essential source of the heater core supplying heat to the inside of the vehicle, this can impact the warmth of the heat inside the vehicle.

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…).

What’s the temp of a car heater at idle?

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…). It blows at about 70 degrees at idle (an can melt your face off while driving).
