Gates 19800 HVAC Heater Hose - Pipe-1 To Water Pump or Tee To Engine

Gates 19800 Molded Heater Hose Overview

Gates 19800 is a factory-molded HVAC heater hose built for tight engine bays where a straight hose will not route correctly. Made from EPDM, this molded coolant hose is sized with 19 mm (0.75 in) inside diameter ends and a 17.24 in (438 mm) centerline length for OE-style routing.

Compatible with 2004-2008 Suzuki Forenza, Tee To Engine, and with 2000-2002 Ford Taurus and 2000-2002 Mercury Sable, Pipe-1 To Water Pump. It also fits the 2001 Ford Sable, Pipe-1 To Water Pump, with 12-valve engine.

Product Details

This molded heater hose is part of the Gates Molded Heater Hose line, which focuses on OE-style hose shapes for modern vehicles with limited clearance. The molded profile helps match original routing on applications such as the Suzuki Forenza, Ford Taurus, and Mercury Sable, reducing the need to force a universal hose into a factory path. Gates 19800 is also cross-referenced to Four Seasons 64153 for the same application.

Common Uses

• Heater hose routing issues in compact engine compartments
• Coolant hose replacement where a molded OE shape is required
• Water pump-to-pipe hose service on Ford Taurus and Mercury Sable applications
• HVAC coolant circulation repairs on Suzuki Forenza applications
• Replacement of aged EPDM hose showing cracking, swelling, or hardening

Installation Notes

Verify end diameters, centerline length, and routing before installation. Match the molded shape to the original hose path and confirm clearance around nearby components, especially in tighter engine bays. Use the vehicle’s factory routing and inspect adjoining clamps, pipes, and fittings for wear before reassembly.

Quality Assurance

Gates manufactures this molded coolant hose as an OE-style replacement built to factory-molded dimensions for the listed applications. The EPDM hose construction is selected for coolant, water, and air service, with marine application approval noted by the manufacturer.
