  Q: How to replace the heater core on Volvo 960?

  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.
