Gates 19712 HVAC Heater Hose - Heater To Pipe-1

Gates 19712 Molded Heater Hose Overview

The Gates 19712 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. With a 19 mm (0.75 in) inside diameter at both ends and an 18.8 in (478 mm) centerline length, it is a direct-fit style solution for heater-to-pipe routing on select Chrysler and Dodge applications.

Compatible with 1998-2004 Chrysler Concorde, heater to pipe-1, 1999-2004 Chrysler Intrepid, heater to pipe-1, and 1998-2004 Dodge Intrepid, heater to pipe-1, this molded hose supports factory-style routing and fitment.

Product Details

Gates Molded Heater Hose line products are built around factory-formed routing to match the contours used in modern engine bays. This molded coolant hose is intended for heater circuit use and follows the OE-style path needed to connect the heater to pipe-1 location on the listed Chrysler Concorde, Chrysler Intrepid, and Dodge Intrepid vehicles. The Gates 19712 hose uses EPDM material, which is commonly selected for coolant-system service because it handles heat and fluid exposure in automotive HVAC and cooling applications.

This part cross-references Four Seasons 11712 and 64171 for the same application.

Common Problems This Hose Can Address

• Cracked or leaking heater hose at the factory bend
• Incorrect routing caused by a straight universal hose
• Coolant seepage at the heater-to-pipe connection
• Restricted heater flow from a deteriorated hose interior
• Fitment issues in tight engine compartments

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. Match the molded shape to the original routing on the vehicle and inspect adjoining heater pipes, clamps, and connection points for wear or corrosion before reassembly. Confirm fitment for the exact year, make, model, and heater-to-pipe-1 position listed for your application.
