Did you know that your heater is engineered for cooling your engine? The center of every vehicular heater is actually a heat exchanger similar to the Gmc T-series heater core. This particular part looks and works pretty much as a radiator inside your cooling system. A heater core functions to receive hot coolant from the engine into the inlet and makes use the attached fins to increase transfer of heat to fan-forced air. Heat that your heater core produces is used to bring heat in the interior.

The Gmc T-series heater core is situated under the dash panel. The first part you'll notice certainly is the fins that are connected to brass or aluminum tubes. It's attached to the engine and the vents of your vehicle via discharge lines. The level of heat that's vented out to the cab is usually controlled through a knob or switch tab on your control panel.

Gradually, this component is going to malfunction. You do not need to endure low overall performance and/or change the entire assembly to recover the Gmc T-series heater core performance. Parts Train offers OES Genuine, Vista-Pro Automotive, or Replacement heater core replacement products for you to select from.
