Gates Premium Molded HVAC Heater Hose

Gates Premium Molded HVAC Heater Hose is a factory-style molded heater hose, also called a molded coolant hose. It carries engine coolant between the engine and the heater core in your vehicle's heating and cooling system. The molded shapes follow OEM-style routing. This helps the hose fit tight engine compartments without kinking.

Key Features:

• Factory-molded, OEM-style construction made for a precise fit
• Engineered to resist electrochemical degradation, a leading cause of hose failure
• EPDM tube and cover with synthetic fiber knit reinforcement
• Temperature range of -40°F to 275°F (-40°C to 135°C)
• Meets SAE 20R3 Type EC Class D-1 and D-2 specifications
• Suitable for coolant, water and air applications, and approved for marine use

Replacing an aged or worn heater hose helps maintain steady coolant flow and heater performance. It also helps reduce the risk of leaks and overheating. Gates is a long-established name in hoses and belts, and this line is built to meet or exceed original-equipment expectations.
