Gates 19306 HVAC Heater Hose - Heater To Pipe-1

Gates Molded Heater Hose 19306

Gates 19306 is a molded HVAC heater hose built for tight engine bays where a straight hose will not route cleanly. This OEM-style coolant hose is formed to match factory routing and is suitable for coolant, water, and air service, with marine application approval.

Key Features

• Factory-molded, OE-style heater hose for precise routing
• EPDM construction for heater and coolant service
• End I.D. 0.62 in. (16 mm) on both ends
• Centerline length: 19.21 in. (488 mm)
• Fits heater-to-pipe applications in select Ford trucks and vans
• Gates molded heater hose line for compact engine compartment layouts

Product Details

The Gates Molded Heater Hose line is built for modern engine compartments with limited clearance and complex hose paths. Part number 19306 uses a molded shape to follow the original routing more closely than a universal hose, helping maintain proper fit in heater circuit service. It is a practical replacement for select Ford Excursion, Ford E-350 Super Duty, Ford E-350 Club Wagon, Ford F-250 Super Duty, and Ford F-350 Super Duty applications where the hose runs from the heater to pipe-1.

This part cross-references Dayco 71986 for the same application.

What It Helps Address

• Cracked or aged heater hose material
• Improper routing in tight engine compartments
• Coolant seepage at a worn hose section
• Restricted heater circuit flow caused by hose deterioration
• Fitment issues when replacing a molded heater-to-pipe hose

Installation Notes and Tips

Verify the hose route, end diameters, and centerline length before installation. This molded hose is listed for heater-to-pipe-1 positions on 1999-2005 Ford Excursion, 1999-2004 Ford F-250 Super Duty, 1999-2004 Ford F-350 Super Duty, and 2004 Ford E-350 Club Wagon and E-350 Super Duty applications. Confirm the vehicle does not require an auxiliary heater configuration before ordering for the Ford Excursion.

Quality Assurance
