About the Molded Heater Hose Product Line

The Molded Heater Hose line from Gates focuses on delivering pre-formed hoses that replicate original equipment shapes and dimensions.

Installation Notes and Tips

Ensure the vehicle is cool before beginning installation to avoid burns from hot coolant. Verify the hose routing matches the original configuration to prevent kinks or stress points. Use appropriate clamps to secure the hose ends firmly without over-tightening, which could damage the EPDM material. Inspect adjacent components for wear or damage during replacement.
