How to replace the Heater Core on Chevrolet Express 1500?

Engine coolant draining should be the first step before starting heater core replacement. The Hose Clamp Pliers (J 38185) should be used to slide off the hose clamps which allow you to separate the inlet and outlet heater hoses from the heater core. You must cut the identified section next by removing the screws from the heater assembly before gently opening the heater core access door. The next step requires removing both the retainers and heater core after cutting. Insert the new heater core into its placement before attaching the retainers and tightening their screws to 1.9 N.m (17 lb in). Replace the heater core access door followed by its retaining screws which you should tighten to 1.9 N.m (17 lb in). Secure the inlet and outlet heater hoses to the heater core by using Hose Clamp Pliers (J 38185) before filling the engine coolant.
