What It Helps Address

• Coolant leakage at a deteriorated heater hose
• Restricted heater core coolant flow
• Improper bypass routing in the cooling system
• Cracking or softening from heat and coolant exposure
• Electrochemical degradation in the hose material

Installation Notes and Tips

Verify hose routing, inside diameter, and molded shape against the removed part before installation. Confirm the heater outlet location and inspect adjoining clamps, fittings, and nearby coolant passages for wear or corrosion. After installation, refill and bleed the cooling system according to the vehicle service procedure to help prevent air pockets.

Quality Assurance

Continental manufactures this heater hose to SAE 20R3EC Class D1 and Class D2 requirements and specifies resistance to electrochemical degradation for added durability in coolant service.
