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.
What else can I help you with?
Can a thermostat cause your car's heater to blow warm air?
Yes.
What is the purpose of a heater matrix?
Called a Heater Core in North America. This is a little radiator to make the air in the car warm
Why does the heater blow cold air instead of warm air?
The heater may blow cold air instead of warm air due to issues such as low coolant levels, a malfunctioning thermostat, a clogged heater core, or a faulty blend door. These problems can prevent the heater from properly warming the air before it is blown into the car.
What is a heater core's purpose in a car?
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.
Why does your car heater take so long to shift from heater to defroster?
The delay in shifting from heater to defroster in your car is primarily due to the time it takes for the engine coolant to warm up. The heater uses hot coolant from the engine to warm the air, and until the engine reaches a sufficient temperature, the air blown into the cabin will not be warm enough for defrosting. Additionally, the defroster setting often requires the air to be redirected through a different duct, which may also contribute to the delay.
How long should a car heater take to warm up?
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.
Why does Car heater only works while driving?
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.
What can be the problem if my car's heater only outputs lukewarm air?
It can be the heating block, which only needs to be replaced before you start getting warm air again.
How hot is the air coming from a car heater?
The air coming from a car heater can typically reach temperatures between 120°F to 160°F (49°C to 71°C) or even higher, depending on the vehicle and the settings. This warm air is produced by circulating engine coolant through the heater core, which then warms the air blown into the cabin. The actual temperature can vary based on factors such as the outside temperature, the car's engine temperature, and the heater's settings.
Why does the car heater blow cold air until driven for a while?
it has to heat up, just like water has to warm in the faucet.
The heat goes out when the car over heats?
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
Vw golf mk3 automatic you have changed the heater core because only warm air comes out but its the same only warm air thermostat water pump is ok and all the pipes are clear and the flap on the heater?
If that car has a temp blend door actuator, it could be faulty.
