Take off the vehicle housing for the heater-A/C first and the foam gasket coming out of the core tubes second, remembering its unusual shape for correct installation. Subsequently, remove the screws and retainers at the joint of the heater core and tubes to the heater-A/C housing. If additional space is needed, take out the mode door actuator. Take hold of the heater core and draw it up and out of the housing; in case of individual tube replacements, undo and pull the round wire-to-core clamp before removing the tube from the core. First, slide the tube into the core and verify the tube O-ring is in place and not being squeezed, while you hold the tube so you can install the tube-to-core clamp. Place the core in its position, secure the tube-to-heater-core clamp after setting the tubes and then fit the heater-A/C housing onto the core. Put the heater core into the heater-A/C housing, put the mode door actuator back if it was taken off and attach the retainers to the heater core tubes with screws tightened to no more than 2.2 Nm (20 in. lbs.). Afterward, fasten the grounding strap to the lower heater core retainer and put the heater-A/C housing back in the vehicle.
