How do you remove a Heater Core?

To remove the air conditioning system, start by having it discharged by a dealership service department or an automotive air conditioning facility. Disconnect the cable at the negative terminal of the battery and drain the cooling system. Remove the heater hoses and air conditioning lines from the fittings at the firewall, plugging the lines to prevent coolant spillage. Remove the instrument panel assembly and pull back the carpeting to remove the rear floor duct. Remove the instrument panel carrier and the nuts securing the HVAC module to the firewall. Withdraw the unit and remove the screw and clamp securing the heater core pipes. Carefully pull out the heater core. For installation, reverse the removal steps and ensure any original insulating/sealing materials are in place around the heater core pipes and core. Refill the cooling system and have the air conditioning system charged by the shop that discharged it. Start the engine and check for proper operation.

GMC Canyon Heater Core

The Heater Core in GMC Canyon vehicles is the part of the heating system mechanism of the car as it works like a radiator and has the engine's the hot coolant scrambled to warm up the air inside the car. Constructed from aluminium or brass with fins to increase the surface area of the core, the hot coolant from the engine passes through the core and with the help of vehicle's blower, air is passed through the core to warm the interior of the vehicle. Heater Cores could have a Valve or a door for temperature regulation while other sophisticated models could use Electromechanical Actuators and Thermistors to ensure extra comfort. In vehicles having air conditioning the heater core assists in the dehumidification process or in reheating air which is cooled. These are problems such as blockage, dripping, and, rusting that call for a complicated process of dismantling the dashboard. It is also possible to use different types of heating for air-cooled engines; however, these procedures are rather dangerous.

Each OEM GMC Canyon Heater Core we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
