Detailed Product Description

This Gates molded coolant hose is part of the Molded Heater Hose line, which is built around factory-shaped hose routing for vehicles with limited clearance. Part number 12187 is formed to follow the original path in the cooling and HVAC circuit, helping maintain proper hose alignment in applications such as the Tesla X right radiator to 3-way valve and the 2004 Jeep Grand Cherokee heater outlet. If you are searching for a molded heater hose for Tesla X or a replacement heater hose for Jeep Grand Cherokee 2004, Gates 12187 is the direct OE-style option to review.

This part cross-references Carlson 13187 for the same application.

Common Problems This Hose Can Address

  • Cracked or leaking molded heater hose sections
  • Collapsed or softened coolant hose routing in tight spaces
  • Incorrect hose shape after prior repair or replacement
  • Restricted coolant flow caused by aged EPDM hose material
  • Fitment issues in radiator-to-valve or heater outlet routing

Installation Notes and Tips

Verify hose routing, end diameter, and centerline length before installation. Confirm the vehicle position listed for your application, since this hose is used at the right radiator to 3-way valve on Tesla X models and at the heater outlet on the 2004 Jeep Grand Cherokee. Inspect adjoining clamps, fittings, and mating surfaces for wear or corrosion before transferring the new hose into place.
