ContiTech 63517 Molded Heater Hose

The ContiTech 63517 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 underhood environments.

Key Features:

• EPDM tube and cover with synthetic knit reinforcement for 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 and is resistant to Electrochemical Degradation (ECR)
• Operating temperature range: -40°F to 275°F (-40°C to 135°C)
• Pre-formed to original equipment specifications for easy installation

ContiTech heater hoses are engineered to withstand high underhood temperatures and resist antifreeze coolants, providing reliable coolant transfer for optimal engine temperature management. This molded hose eliminates the need for multiple bends and clamps, reducing potential leak points in your cooling system.
