What causes coolant to leak from the heater core?
When the corrosion inhibitors are depleted, the cooling system can become corroded, filled with contaminants and may even start to leak. Coolant/antifreeze leaking out through the heater core means that the overall coolant level in the system will be low and the engine is in danger of overheating – the most common cause of mechanical breakdown.
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.

How can you tell if your car heater core is bad?
The antifreeze or coolant is the main ingredient that keeps your coolant system and car cool. If the odor is strong inside the passenger compartment, it’s a sign you have a bad heater core.

Where is the heater core in a car?
As said earlier, the location of the heater core is behind the dashboard on the passenger side. If your heater core is leaking coolant, that means the coolant level is low. As such, the engine can overheat. This is one of the main causes of mechanical breakdown.
If the leak has happened in the heater core itself, which is located behind the dashboard of your car, it may run out from behind the panels of your dashboard. Often, you’ll see this running down the inner walls of the centre console down by your feet or the feet on the passenger side of the vehicle.
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.
How is the temperature of the heater core controlled?
Some vehicles have a heater valve that directs coolant through the heater core when the heat is on and bypasses the heater core when the heat is off. In other vehicles, the temperature of the air is controlled within the air blend box by how much air is directed over the heater core.
Can a bad heater core cause an engine to overheat?
Even a clogged heater core has the potential to obstruct coolant flow enough to cause overheating. A low coolant level (caused by a leaking heater core) can lead to overheating and possible engine damage. What Causes a Bad Heater Core?
Why is there no heat after a coolant flush?
Well, if you have leakage in the radiator cap, air can enter easily in the cooling system. Many times, when you flush the cooling system, gunk enters into the heater core and clogs it up. As a result, the heater core fails to provide warm air.
Where does the hot engine coolant go in a car?
Hot engine coolant enters the heater core through the inlet pipe. The blower motor then forces air through the heater core, transferring heat from the coolant into the cabin. Note: It’s important to remember that the heater core is part of your car’s cooling system; it relies on hot engine coolant circulated by the water pump.
Even if you have an older vehicle with the heater core outside the cabin, leaking fluid can still find its way into the cabin through the ventilation ducts. Having coolant leaking into the cabin of your vehicle can cause all sorts of problems.
