Can you flush a heater core with air compressor?

A heater core can be flushed with just water (and will need to be flushed with water either way), but using an air compressor tends to be better at breaking up hard to remove clogs. As the air compressor builds up pressure in the heater core, it will move the grime and coolant out of the inlet hose, into the container.

How do I purge the air from my heater core?

​Start the engine of your car and allow it to warm up for a while. ​Once it reaches the operating temperature, the heater valve automatically allows the coolant to flow through the heater core. This action pushes the air bubble outside. ​Leave the car idle in this state for 15-30 minutes.

What happens when your heater core goes out?

If you find that when you turn the heat on even after the engine has been running for a while and nothing is happening, then that’s a good sign your heater core has failed. This can be the result of any number of potential problems from a leak in your coolant system to a buildup of sediment that gets clogged in the heater core.

Is it possible to repair a leaking heater core?

Can I repair a leaking heater core? Fixing a leaking heater core will always be much easier than replacing one.   Since it is only a small leak in the heater core, we recommend simply sealing that leak and leaving your heater core in place.

What should I do if my air conditioner core is failing?

The heater hoses should be inspected when replacing a heater core. Problems with the heater hoses can cause similar problems to a failing heater core and are less expensive to correct. Some cars will need to have the air conditioning system recharged, which can increase the cost of repair.

Where does the heater core need to be?

The heater core needs to be right next to the fan that pushes the air through your ventilation system. That fan needs to be near the firewall of your car so it can have the ability to both pull air in from outside the vehicle, or recirculate the air in the cabin depending on the settings of the system.
