Gates Molded Heater Hose

Gates Molded Heater Hose is a preformed heater hose (also called a molded coolant hose or HVAC heater hose) that carries engine coolant between the engine and the heater core. Each hose is molded to a specific shape so it routes cleanly and fits without kinking.

Key Features:

• Molded construction: The preformed shape follows the original routing, which helps prevent kinks and collapse.
• Reinforced design: Reinforcement gives the hose strength under the pressure and temperature cycling of a cooling system.
• Coolant-resistant materials: The rubber compounds are made to resist heat, ozone, oil, and the effects of modern coolants.
• Consistent quality: Gates is a long-established supplier of belts and hoses to automakers and the aftermarket, so these hoses are built to a fit and quality standard.

Replacing an aging heater hose helps prevent leaks, coolant loss, and overheating. It also helps keep cabin heat and defrost working reliably. When you replace a hose, it is good practice to inspect the clamps, the connections, and the coolant condition at the same time.
