Product Details

Gates Molded Heater Hose 18413 is formed to follow the routing needed in smaller, tighter-fitting engine compartments. The molded profile helps match the original hose path at the tee to water pump location, which is important when replacing a worn or collapsed hose in Jeep Cherokee, Jeep Comanche, or Jeep Wagoneer models from 1987 through 1990. The EPDM material is suited for heater and coolant service, while the small inside diameters and 25-inch centerline length support accurate fitment in the cooling system.

This part cross-references Continental 63146 for the same application.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged heater hose
• Restricted coolant flow caused by hose collapse or softening
• Poor routing in a tight engine compartment
• Incorrect hose shape after a previous repair
• Service issues at the tee to water pump connection

Installation Notes and Tips

• Verify the hose routing and end diameters before installation.
• Inspect adjoining clamps, fittings, and water pump connections for wear or corrosion.
• Match the molded shape to the original routing on the vehicle.
• Confirm fitment for the specific Jeep Cherokee, Comanche, or Wagoneer model year before ordering.
