Product Details

Continental’s Molded line focuses on formed hose routing for cooling and heater-circuit service, helping maintain the original path and fit of the vehicle’s coolant plumbing. This hose transfers glycol-based coolant to and from the heater core, bypasses to the radiator, and moves coolant through other vehicle components as required by the system layout. For buyers searching for a heater hose for 1999-2006 Chevrolet Silverado or 1999-2006 GMC Sierra cooling-system repair, 62937 provides a direct-fit molded configuration for the listed applications.

This part cross-references 15734738 and L-62937 for the same application.

What It Helps Fix

• Coolant leaks at a worn or cracked heater hose
• Restricted coolant flow between the reservoir and radiator
• Improper hose routing caused by a damaged molded hose
• Heat-related hose softening or deterioration
• Electrochemical degradation in the cooling circuit
