ContiTech 63146 Molded Heater Hose

The ContiTech 63146 is a molded heater hose designed to transfer glycol-based coolants to and from the heater core, by-pass to the radiator, as well as through other components in the vehicle's coolant system. This precision-molded hose features original equipment configurations to ensure proper fit and reliable performance in demanding automotive cooling applications.

Key Features:

• EPDM tube and cover with synthetic knit reinforcement for superior durability
• Compatible with most coolants including ethylene glycol- and propylene glycol-based coolants, as well as organic acid modified, long-life coolants
• Meets or exceeds SAE 20R3EC Class D1 and Class D2 specifications
• Resistant to Electrochemical Degradation (ECR) for extended service life
• Wide temperature range: -40°F to 275°F (-40°C to 135°C)

This molded heater hose is engineered to withstand the harsh underhood environment while maintaining flexibility and proper coolant flow. The precision molding ensures the hose routes correctly without kinking, buckling, or creating stress at connection points. Not for use in fuel or oil transfer applications.
