Create a large driving hazard. Because the heater core is usually located under the dashboard inside of the vehicle and is enclosed in the ventilation system's ducting, servicing it often requires disassembling a large part of the dashboard, which can be time-consuming and therefore expensive. edit Air cooled engines Engines that do not have a water cooling system can not use a heater core; one alternative is to guide air around the (very hot) engine exhaust manifold and then in to the vehicle's interior. Temperature control is achieved by mixing with unheated outside air. edit See Also Look up heater core in Wiktionary, the free dictionary.

heater core attached to the core tubes serve to increase surface for heat transfer to air that is forced past them heater core, by a fan heater core, thereby heating the passenger compartment. Contents 1 How it works 2 Control 3 Air conditioning 4 Engine cooling function 5 Possible Problems 6 Air cooled engines 7 See Also 8 External Links edit How it works The internal combustion engine in most cars and trucks is cooled by a water and antifreeze mixture that is circulated through the engine and radiator by a water pump to enable the radiator to give off engine heat to the atmosphere. Some of that water can be diverted through the heater core to give some engine heat to the cabin. Heater core heater core.
heater core (arrowed) in the partially disassembled dashboard of a BMW E32. A heater core is a small radiator heater core, located under the dashboard of the vehicle and consists of conductive aluminum tubing with cooling fins to increase surface area. Hot coolant passing through the heater core heater core, gives off heat before returning to the engine cooling circuit. The fan for the vehicle's ventilation system forces air through the heater core to transfer heat from the coolant to the cabin air heater core, that is directed into the vehicle through vents at various points. edit Control Once the engine has warmed up heater core, the coolant is kept at a more or less constant temperature by the thermostat. The temperature of the air entering the vehicle's interior can be controlled by using a valve limiting the amount of coolant that goes through the heater core. Another method is blocking off the heater core with a plastic door heater core, directing part (or all) of the incoming air around the heater core completely heater core, so it does not get heated. Some cars use a combination of this system. Simpler systems allow the driver to control the valve or door directly (usually by means of a rotary knob). More complicated systems use electronics to control the valve or doors. Cars with dual climate function (allowing driver and passenger to each set a different temperature) may use a heater .

heater hoses, one in and one out to the heater core. We would recommend, "looping" the two heater hoses taking the heater core out of the system. Do not plug the hoses. Question: 1999 Range Rover 620i mileage: 72,000. A strong smell of anti-freeze in front & rear seating area, which clears after heating has been on for five minutes but after engine has stopped parked smell, comes back. I have checked interior for leaks and underneath car but no sign, also checked radiator cooling system expansion tank windscreen tank all of which appear fine. Answer: Your heater core has probably failed and is leaking coolant. Replacing the heater core should fix your problem. Question: 2003 Ford Focus mileage: 113,000. When I first start my Tempo in the morning it sounds like water running somewhere and I can smell anti-freeze. I checked my anti-freeze level it is ok. Answer: The water running sound that you hear is probably caused by air in the cooling system. As the air and coolant go
