Gates 19193 HVAC Heater Hose - Heater To Pipe-1

Gates Molded Heater Hose 19193

The Gates 19193 molded heater hose is an OEM-style coolant hose built for tight engine bays where a straight hose will not follow the factory routing. Made from EPDM and factory-molded to the correct shape, it supports coolant, water, and air applications and is approved for marine use.

Compatible With 1997-2012 Ford F-150, F-250, F-350, Expedition, and 1998-1999 Lincoln Navigator heater-to-pipe applications, this molded heater hose also covers select Chevrolet Colorado, GMC Canyon, Hummer H3/H3T, and Isuzu i-Series fitments. Gates Molded Heater Hose line parts are shaped for direct routing in compact engine compartments, helping maintain proper hose alignment around nearby components.

Key Features

• EPDM construction for heater hose and coolant service
• Factory-molded shape for OEM-style routing in tight spaces
• End I.D. of 16 mm (.63 in) on both ends
• Centerline length of 516 mm (20.3 in)
• Fits heater-to-pipe-1 positions across multiple Ford, GM, and Isuzu applications
• Approved for marine applications

Application Details

Part number 19193 is a molded heater hose designed around factory routing requirements for vehicles with compact engine compartments. It is used on heater-to-pipe connections where the hose must follow a specific bend profile rather than a universal straight run. This makes it a practical replacement for Ford F-150 and F-250 heater hose service, as well as select Chevrolet Colorado and GMC Canyon heater hose applications.

This part cross-references Continental 63991 for the same application.

Common Problems It Can Address

• Cracked or heat-aged heater hose material
• Incorrect hose routing after prior repairs
• Coolant seepage at a worn heater-to-pipe connection
• Interference caused by a hose that does not match factory bend shape
• Service replacement for molded hose applications on Ford, GM, and Isuzu trucks/SUVs

Installation Notes and Tips

• Verify the vehicle’s heater-to-pipe routing before installation.
• Match the molded shape and both 16 mm end diameters to the original hose.
• Inspect adjoining pipes, clamps, and sealing surfaces for wear before reassembly.
• Confirm clearance around nearby components in tighter engine compartments.

Quality Assurance

Gates manufactures this molded heater hose as an OEM-style replacement built to the listed dimensions and fitment data. The molded EPDM construction and factory-shaped profile support consistent routing for the specified applications.
