Does coolant affect car heater?
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. When your car is low on coolant, it won’t be able to send any to the heater core to create warm air.
Why is my heater not working in my car?
A heater can stop working for a number of reasons, including: A low antifreeze/water level in the radiator due to a leak in the cooling system. A bad thermostat that isn’t allowing the engine to properly warm up. A blower fan that isn’t working properly.
What to do if your heater is blowing cold air?
Coolant level: If your coolant level is low, your heater core may not be getting enough warmed coolant through it to produce adequate heat. Solution: Top up the coolant and see if it helps. If the level is low due to a leak, track down the source and get it repaired.
Why does my car heater keep blowing cold air?
There are many reasons your car’s heater isn’t working. Maybe the fan is malfunctioning. Perhaps your temperature gauge is running below normal.

What to do if your car heater is not working?
Solution: Set the heater to its maximum setting, remove the coolant tank cap and fill it to the proper level. Start the engine with cap still open and let the engine idle for a few minutes. If the coolant level should drop as the thermostat opens, top it up as necessary.
What causes an air lock in a hot water heater?
Air lock: An air lock is a large air bubble that forms in your cooling system as the result of a coolant leak or a recent coolant top-up. An air lock prevents the coolant from circulating properly and can cut your heat output. Solution: Set the heater to its maximum setting, remove the coolant tank cap and fill it to the proper level.
