If you’re thinking about removing heater core without removing dash of your car then it is easy. There are many side effects of a leaking heater core, which can damage your vehicle in the long run. The car’s superb coolant travels via the core’s coiled tube, a heat exchanger that lies between the coolant and the cabin air. As a result, the heater core is a part of a vehicle’s cooling system. The heater core must be in excellent functioning in order to keep the engine from overheating. It is thus vital to be aware and learn to identify when the heater core is not operating.
What Is A Heater Core?
The heater core is a small radiator that warms the car’s cabin using hot coolant from the engine. The cooling system’s hoses circulate liquid coolant through the heater core as they do through the engine and large cooling radiator behind the vehicle’s grille.
A failed heater core is a common source of liquid in the vehicle’s front footwells, with steam coming from the air vents or excessive fogging of inside windows. A sweet coolant odor is another sign of failure.
How Does A Heater Core Work?
Before discussing removing heater core without removing dash of your car. Firstly, let’s see how a heater core work. The working of a heater core is less complex and can be easily understood. It works on an internal combustion engine where a water and antifreeze mixture is used in cooling the engine parts. Thus, during the cooling process, the hot coolant goes the extra mile to produce warmness in the vehicle’s interior.
As soon as the engine is warmed up, the temperature of the coolant is controlled by the thermostat. Some of the hot coolants are diverted through the heater core, and the temperature of the air entering the car’s interior is controlled by the valve, limiting the amount of coolant that goes through the heater core. The flow of the warm air can also be controlled or blocked with a door, which directs all the incoming air around the heater core. This causes the system not to get heated or re-heated when the air conditioning compressor is working.

3. Your Car Is Blowing Cold Air Into The Cabin:-
When a hole or puncture develops in the heater core, all that warm air may escape too quickly to reach you at the other end of the heater ducts. Depending on the size of the puncture, you might feel mildly warm, lukewarm, or absolutely freezing air coming from your heater.
4. Your Car Is Devouring Coolant-
If you find your vehicle has suddenly been needing a higher than usual amount of coolant and you cannot figure out why it could be a blown heater core. If the leak is hard to find, the coolant may leak into your cabin when the system is cold, and instead of making fog, is creating a puddle.
