It is your car's cooling system that removes the excess heat from the engine. Then, by a convection process, transfers that heat to your heater core. The heater core in your car is similar to the radiator in the front of your car; in fact it looks like a small radiator. The difference is the heater is mounted inside the car and air is blown through the fins of the core. The heater hoses transfer engine coolant to the heater core, this allows the heat from the engine coolant to be utilized and warm the passenger compartment air. The heat transferred lowers the temperature of the liquid coolant, which is then circulated back to the engine to absorb excess heat again, a continuous system. Whereas the radiator is located at your car's front grill, the unit that transfers heat to the passenger cabin ( heater core) is located inside the dashboard. Heated liquid coolant circulates through tubes in the heater core, and a heater fan blowing across those tubes, as well as through little fins encasing the tubes, directs warmth through the heating vents into your car's passenger cabin.
Yes.
Called a Heater Core in North America. This is a little radiator to make the air in the car warm
It acts like a small radiator to warm the interior. Warm/hot coolant from the engine circulates through it, while air blows across it. This air is warmed by the coolant, then is directed into the passenger compartment to warm the car.
How long it takes a car heater to warm up depends on the temperature outside. In cold weather the heater can take several minutes to warm up.
Most (not all) cars are heated by the engine. When fluid moves through the engine it heats up. This fluid moves through the heater core, a fan moves air over the warm heater coils blowing warm air out to the cars cab.
It can be the heating block, which only needs to be replaced before you start getting warm air again.
it has to heat up, just like water has to warm in the faucet.
If that car has a temp blend door actuator, it could be faulty.
the reason that the heat would cease to work when the car overheats is that the car is low on coolant. coolant is warmed by the engine as it transfers heat away from the engine. the heated coolant passes through heater hose and through the heater core. The blower motor blows air through the heater core warming the air and pushes the warm air through the vents in the car to you. the heater core is a small radiator in the dashboard of most vehicles. If there isn't coolant in the car, the engine becomes too hot thus the overheating. a side effect of this is that the lack of coolant means that coolant cannot get to the heater core to be warmed to warm you
[first time answering questions] car heater works like the reverse of the normal cooling radiator - in fact the heater is like a small version of the rad that's on the frnt of the car - the hot water from the engine block goes into this small rad and the heater fan blows air thru it into the car - the hot heater rad loses heat into the car and - bingo - you get warm inside
Our car had this problem. Answer was a new A/C computer needed.
I assume the blower motor is going. There might be an air bubble preventing the warm water from circulation through the heater core, you might have a build-up of sludge doing the same. Or maybe there's something broken in the valves in the air ducts preventing the heater from releasing warm air into the car.
