How is the core of a heater heated?
Since the liquid flowing in and out of the heater core is constantly heated by the engine, the only other component necessary to produce heat is a fan blowing air through the heater core (much like the radiator, except the air enters the cabin.) A broken loop.
Where does the coolant go in a heater?
The heater core is part of continuous loop of engine coolant propelled via the water pump, flowing through caverns in the engine, through pipes that run through the firewall into the heater core, back out the firewall, and finally through the radiator. If the thermostat dictates it…
How does heat transference work in a heater?
The heater core works through heat transference. Hot radiator fluid goes into the core, the heater fan blows through it, heat is transferred to the cooler air, and heat is transferred into the cabin. The input is radiator fluid directly from the engine and output from the core goes directly back into the engine.
How is a heater core different from a radiator?
While the radiator transfers heat from the hot coolant into the atmosphere, the heater core transfers heat to the cabin. Like your car’s radiator, the heater core is a heat exchanger. But while the radiator transfers heat from the hot coolant into the atmosphere, the heater core transfers heat to the cabin.
How does a car heater core work in a car?
You’ll also notice that the heater core, with its tanks and fins, looks just like a mini radiator. The heater core has an inlet and an outlet pipe that connect to the car’s cooling system. Hot engine coolant enters the heater core through the inlet pipe.
Which is warmer the inlet or the heater core?
Typically, the inlet hose should be about 20 degrees warmer than the outlet hose. If the outlet heater hose is significantly cooler than the inlet hose, the heater core is probably clogged. Note: If both heater hoses are cold, the heater control valve (if the vehicle is equipped) may be faulty.
What happens when a heater core goes bad?
A heater core often goes bad due to leaking. As the heater core uses engine coolant to generate heat, a leaking heater core will reduce the amount of coolant in the cooling system. Low coolant will cause an engine to run at a higher temperature, which can result in extensive engine damage. Can a Bad Heater Core Cause Overheating?
