Volvo 740 Heater Core
The Volvo 740 Heater Core maintains the comfort of the cabin interior and the transparency of the windows by converting engine heat into a continuous stream of warm air. This mini radiator is located below the Volvo dash, to which hot coolant is fed via two hoses, and the dense fins increase air temperature as fresh air is forced across the radiator and into the interior by the blower. In the early model line, Volvo had been using heavier brass and copper cores, which provided greater robustness but added bulk, whereas subsequent models had aluminum cores, which were lighter and faster at transferring heat, the primary structural difference between the two styles. Temperature control is either a simple cable-controlled valve over the coolant flow, or a blend door that diverts air around the core, and in certain higher trim 740 models, a combination with small electric actuators and cabin thermistors that allows fine split-zone comfort for the driver and passenger. With the air conditioner on, the chilled and dehumidified air goes past the Heater Core a second time to undergo a slight reheat, so as to avoid mist on cold mornings. The Heater Core is also a small auxiliary radiator, which contributes to the engine getting rid of additional heat under severe loads. Failure to replace coolant may allow rust and scale deposits to block passages or may start electrolysis that punches holes in the metal, issues that can only be addressed by removing the dashboard, and hence regular maintenance is the key to Volvo reliability.

Volvo 740 Heater Core Parts and Q&A
- Q: How to replace the heater core on Volvo 740?A:Over vehicles with Automatic Climate Control (ACC) until the water temperature for the fan motor exceeds about 95deg F (35deg C) a thermal switch on the outlet hose from the heater core turns on the fan motor to prevent cold air entering the passenger compartment in winter, but is bypassed in defrost mode. For the 240 Series and Coupe, the process starts by disconnecting the negative battery cable and draining the cooling system, then moving the heater controls to the CLOSED position and removing different components such as soundproofing, side panels, the radio, and the center control panel. The glove box assembly and other dashboard elements are then removed, and the heater assembly accessed. The installation includes ensuring that the blower and heater core were properly positioned, surfaces were sealed and all parts were reconnected in the reverse order, checking for leaks and proper operation afterward. The 700 Series is similar, with removal of the battery and draining the cooling system as the beginning procedure, followed by removal of the throttle cable and heater hoses, and various dashboard panels. The installation steps are similar to the 240 Series to ensure that they are clean and properly connected. For models that do not have an ACC, the process involves discharging the A/C system, removing the heater hoses and various console components, installation of the heater core assembly and making sure all connections are secure. In case of vehicles with Electronic Climate Control (ECC), the procedure consists in disconnecting the battery, discharging the cooling system and removing the dashboard to reach the heater core, with special attention to reconnecting all elements and checking for any leakages and proper functioning after the installation.
