Does turning on the heater cool down the engine?
Turn On The Heater It sounds counterintuitive, but Reina recommends turning on the heater. It draws warmth away from the engine and into the passenger compartment, lessening the burden on the engine’s cooling system.
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.
Why does my car heat up in the winter?
Reason #1: Not Enough Coolant. Your car uses coolant – usually made up of 50% antifreeze and 50% water – to cool your engine down, especially during the hot months of summer. During the winter when you crank up your heat, the coolant is brought over from the engine to the heater core that then blows warm air into your car.
Can a car heater be unreliable in the winter?
Unreliable car heaters can make the cold winter months practically unbearable. Several things can potentially go wrong with automotive heaters because, much like a home heating system, there are many components working together to heat your car. If one or more of these issues is present, your vehicle may blow out cool air rather than heat:
Why is my car heater not blowing warm air?
If your car is not blowing warm air into the cabin and the coolant level is fine, then you could have an issue with your heater core. If you suspect that something is amiss with your car’s heater core, watch for these signs:

Why does my car heater keep blowing cold air?
If the thermostat can’t signal to the car that the engine is warm, the coolant won’t be sent over to provide heat to your heater core and the air will stay cool. Thermostats are a relatively easy and inexpensive fix, so installing a new one can get your heater working again quickly. The last common problem with car heaters is a water leak.

Why does my car feel cool for a few minutes?
It can feel cool for the first few minutes because the engine has to warm up in order for the coolant to heat up and provide heat to your interior. If cool air continues to blow out, the first thing you should check is your coolant level. When your car is low on coolant, it won’t be able to send any to the heater core to create warm air.
