About the Molded Heater Hose Product Line

The Gates Molded Heater Hose line is specifically designed to meet the demanding requirements of automotive heating and cooling systems.

The Molded Heater Hose 18741 is part of this line, offering a reliable replacement option for HVAC heater hoses in select Ford, Lincoln, and Mercury vehicles.

Detailed Product Description

This HVAC heater hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids.

Installation Notes and Tips

Ensure the vehicle is cool before beginning installation to avoid burns from hot coolant. Verify hose diameters and length match the original part to guarantee proper fit. Use appropriate clamps to secure the hose ends and check for leaks after installation. The molded design of the Gates 18741 heater hose facilitates alignment with factory routing, reducing installation time.
