Cadillac CTS Heater Hose

Keeping your CTS in top shape is your top priority.

Cadillac car, truck, or SUV owners have come to expect a certain level of performance when driving their CTS around town. While it may not be difficult to buy replacement parts for Cadillac vehicles, these days only the highest quality are required to fix your car or truck. Your Cadillac dealership isn't the only place to find trusted repair parts to fix your CTS. Make no mistake, you didn't buy your CTS unless you understood you would be getting best-in-class service and dependability both rolled up into one vehicle.

The function and purpose of Heater Hose.

Believe it or not, your car or truck's heating system is closely tied to its engine cooling system. The engine of your Cadillac CTS circulates liquid coolant throughout the block to absorb heat, and transfers it through heater hoses to the heater core so you can warm up the passenger compartment. Cadillac CTS 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 re-introduces the coolant to the engine after it has heated the heater core so the radiator can return it to optimum temperature.

Time has come... fix it today.
