Chevrolet Trailblazer EXT Heater Hose

Your Trailblazer EXT is a prized possession.

Select Your VehicleObviously, you bought your Trailblazer EXT because you wanted to buy horsepower and American style both impeccably combined into one vehicle. When your Chevrolet Trailblazer EXT rolled off the assembly line, it was destined for a driver who wants long-lasting quality in their automobile. It's not a regular occurrence that you discover you need a replacement Heater Hose to repair your car or truck. Your Chevrolet dealership isn't the only place to locate the highest quality replacement parts for your Trailblazer EXT.

What Heater Hose does for your vehicle.

Before cars and trucks were built with the ability to cool their interiors, they had the ability to heat them. The engine of your Chevrolet Trailblazer EXT constantly pumps and turns a mixture of water and ethylene glycol through the engine block in order to absorb the heat it generates, and transfers it through heater hoses to the heater core so you can warm up the passenger compartment. Chevrolet Trailblazer EXT heater hoses turn a negative side effect of normal engine operation (engine heat absorbed by coolant) and use it to provide passengers with a pleasant experience. The return heater hose will usually drop the coolant back into the water pump or a by-pass housing in your engine so it can go back to the radiator.
