How to replace the Heater Core on Chevrolet Express 3500?

The first step to install a new heater core requires draining the engine coolant. Using J 39529 Heater Hose Pliers users should disconnect the heater core clamps before removing the heater core inlet and outlet hoses. Using the heater assembly screws first you should access the heater core by carefully opening the door before proceeding to cut the marked area. The heater core removal process starts with cutting the piece after which the retainers must be removed together with the heater core. The first step for installation is to put the new heater core into position then tighten the retainers around it. Insert the new heater core before applying 1.9 N.m (17 lb in) of torque and installing the heater core access door and its retaining screws with a torque value of 1.9 N.m (17 lb in). Secure the inlet and outlet heater hoses on the heater core while using Heater Hose Pliers (J 39529) that tighten the hose clamps. Finally, fill the engine coolant.
