Description
More Comfortable Ride. A functional heater hose is a critical component of your vehicle’s heating system, playing a vital role in maintaining a comfortable interior temperature, particularly during the colder months. The Throttle Body to Heater Core Hose transports hot coolant from the engine to the heater core, where the heat is transferred into the cabin through the vehicle’s ventilation system. When the heater hose is in good condition, it ensures that warm air circulates effectively, providing a cozy and inviting atmosphere for both the driver and passengers.
Tough Build. In addition to providing warmth, this Throttle Body to Heater Core Hose also plays a crucial role in the vehicle's defrosting system. When the windows fog up due to temperature differences between the inside and outside of the vehicle, the heating system helps to clear the glass by directing warm air onto the windshield. A properly functioning heater hose ensures that the heater core can produce enough heat to effectively defrost the windows, improving visibility and safety while driving.
Installation. Putting this Throttle Body to Heater Core Hose on your Corvette takes 1 hour to install.
Warranty There is a limited warranty on this product.
Application. The Throttle Body to Heater Core Hose fits 1988-1991 Corvette models.
