Gates 19819 HVAC Heater Hose - Reservoir To Radiator

Gates Molded Heater Hose 19819 Overview

Gates 19819 is a molded HVAC heater hose built for tight engine bays where a straight hose will not route cleanly. This factory-molded, OE-style hose uses EPDM construction and is sized with 3/4 in. inside diameter ends for coolant transfer in the reservoir-to-radiator path.

Compatible with 2001-2004 Ford Escape and 2001-2004 Mazda Tribute reservoir to radiator applications, Gates 19819 is also suitable for water and air service and is approved for marine use. The molded shape helps maintain the intended routing in compact engine compartments.

Detailed Description

Gates 19819 is a molded coolant hose designed to follow the original routing used in select Ford Escape and Mazda Tribute cooling-system layouts. Its molded profile supports a clean reservoir-to-radiator connection, while the EPDM material is suited for heat and coolant exposure in HVAC and engine-cooling service. If you are replacing a worn Ford Escape heater hose or a Mazda Tribute molded coolant hose, this part number provides the correct OE-style form factor for the listed applications.

The Gates Molded Heater Hose line focuses on factory-shaped hoses for modern vehicles with limited clearance around the engine. That makes Gates 19819 a practical choice when you need a molded heater hose that matches the routing and diameter requirements of the original setup.

What This Hose Helps Address

• Coolant leaks from cracked or aged molded hose sections
• Restricted flow caused by hose collapse or soft spots
• Improper routing in compact engine compartments
• Replacement needs for reservoir-to-radiator hose service
• Wear from heat cycling in Ford Escape and Mazda Tribute cooling systems

Installation Notes and Tips

Verify end diameter, centerline length, and molded shape against the original hose before installation. Confirm the reservoir-to-radiator routing on the vehicle and inspect adjoining fittings, clamps, and connection points for wear or corrosion before transferring the new hose into service. This part is listed for 2001-2004 Ford Escape and 2001-2004 Mazda Tribute applications with 3/4 in. I.D. hose routing.
