The ContiTech 63511 is a precision-molded heater hose engineered to transfer glycol-based coolants to and from the heater core, by-pass to the radiator, and through other critical components in your vehicle's cooling system. This pre-formed hose features original equipment configurations to ensure a proper, leak-free fit.

Key Features:

• EPDM tube and cover construction with synthetic knit reinforcement for durability
• Compatible with ethylene glycol, propylene glycol, and 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
• Temperature range: -40°F to 275°F (-40°C to 135°C)
• ID range: 1/4-inch to 1-3/8-inch configurations

This molded heater hose is designed specifically for coolant transfer applications and should not be used for fuel or oil transfer. The precision molding ensures proper routing and fitment, eliminating the need for trimming or custom bending during installation.
