GMC Sonoma Heater Core
Heater Core in GMC Sonoma vehicles is responsible for delivering heat to the cabin by using waste engine heat. Similar to a miniaturized radiator, the central component is cooled by a water and anti-freeze solution with the heated coolant from the car's engine flowing through it. Cooled air is circulated through the core by the vehicle's fan where it is heated to warm up the cabin air. Various types of the heater core not only consist of the airflow control chamber but also might contain the temperature control in form of valve or door for film coolant regulation and sophisticated car heating systems are equipped with electromechanical actuators for the temperature control. In a car, the heater core assists in removing condensation from air conditioning by reheating it specifically in air-conditioned Sonoma vehicles. Some of the problems that may be experienced with heater cores include blocking, cases of leakage and corrosion and since the heater core is located within the dashboard it is often very tedious and expensive to repair.
Each OEM GMC Sonoma 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.
GMC Sonoma Heater Core Parts Questions & Experts Answers
- Q: How do you remove the heater core on GMC Sonoma?A: To remove the heater core in a 1997 and earlier model, start by disconnecting the battery cable at the negative terminal and draining the cooling system. Then, disconnect the heater hoses at the engine side of the firewall and plug the open fittings. The heater core housing is located behind the dash, with the rear cover housing needing to be removed to access the heater core. Begin by removing the lower dash panels and the pivot bracket bolts under the dash. Lower the steering column and remove the bolt on the bottom right of the dash. Pry up the speaker grilles and defroster outlet grille to access hidden bolts. Once all fasteners are removed, pivot the dash rearward to access any cables that need to be disconnected. Disconnect the main electrical harness plug on the right side of the dash and remove the entire dashboard assembly. With the cover for the heater core exposed, remove the pencil brace and the screws holding the cover to the housing. Remove the straps and bracket, then carefully pull out the heater core. For a 1998 and later model, the entire heating/ventilation module must be removed from the firewall. Disconnect all electrical and vacuum connectors, remove the blower motor resistor, and reach through the resistor hole to remove the engine-side bolt securing the module. Inside the vehicle, remove the mounting nuts and bolts, then pull out the module. To remove the heater core, remove the screws on top of the module, remove the cover, and slide out the heater core. Installation is the reverse of removal, making sure to refill the cooling system and check for leaks and proper operation of the heating system.
