  Q: How to replace the Heater Core on Buick Terraza?

  A: The first step when replacing the heater core involves draining all cooling system contents. The job requires using Hose Clamp Pliers (J 38185) to disconnect heater hose clamps which are situated at heater core locations. Before disconnection install caps at the inlet and outlet pipes of the heater core to avoid interior coolant leakage in the vehicle. The replacement of the heater core starts by dismantling the heater core cover after releasing the heater core pipe clamp screw before removing the heater core itself. The first step for installation involves placing the new heater core properly before tightening the heater core pipe clamp screw to 1.2 N.m (11 lb in). The installation process begins with the heater core cover and ends with heater hose attachment to the heater core while tightening hose clamps with Hose Clamp Pliers (J 38185). The final step is filling the coolant to finalize the installation procedure.
