Product Details

This Continental heater hose is designed for vehicles that use a molded coolant hose between the heater core, heater valve, thermostat area, auxiliary water pump outlet, or pipe-to-pipe routing. It is a direct-fit style replacement for applications such as 2003-2005 Honda Pilot heater to valve, 1998-2000 Honda Civic heater to pipe, and 2006-2008 Ford Explorer heater to valve. The molded shape helps match factory hose routing, while the ECR-resistant construction addresses one of the common causes of heater hose deterioration. This part number is 63106, and it cross-references Gates 18748 for the same application.

Installation Notes

Verify hose routing, end diameters, and molded shape before installation. This hose is listed for specific heater-to-valve, heater-to-pipe, valve-to-engine, and similar coolant paths, so match the vehicle position and notes exactly. Inspect adjoining pipes, clamps, and heater valve connections for wear or corrosion before installing Continental 63106.
