Gates 19888 HVAC Heater Hose - Reservoir To Lower Hose

Gates Molded Heater Hose 19888 Overview

The Gates 19888 molded heater hose is a factory-molded, OE-style coolant hose built for tight engine bays where a straight hose will not route correctly. It is made from EPDM and is suitable for coolant, water, and air service, with marine application approval noted by the manufacturer.

Compatible With 2010-2012 Ford Fusion and 2010-2011 Mercury Milan reservoir to lower hose routing, this molded heater hose supports the original hose path and connection geometry. The Gates Molded Heater Hose line focuses on formed replacement hoses that match the shape needed in compact HVAC and cooling system layouts.

Detailed Description

Gates 19888 is a molded heater hose engineered for applications that require a formed hose profile rather than a universal straight section. Its small inside diameter and 29.5-inch centerline length help it follow the original routing in tighter engine compartments, reducing the need to force the hose into position. For Ford Fusion and Mercury Milan cooling system service, this part number 19888 provides the correct molded layout for the reservoir to lower hose path.

This Gates molded heater hose is part of the Molded Heater Hose product line, which is aimed at replacement fitment where shape and routing matter as much as diameter. The EPDM material is commonly used in coolant service for its resistance to heat and fluid exposure in automotive HVAC and cooling circuits.

Common Problems It Can Address

• Cracked or leaking heater hose at the reservoir to lower hose route
• Collapsed or kinked hose caused by tight engine bay routing
• Incorrect hose shape after prior repair or replacement
• Coolant seepage from aged EPDM hose material
• Poor hose alignment in Ford Fusion or Mercury Milan cooling system service

Installation Notes and Tips

Verify hose routing against the original part before installation and confirm both end diameters match the vehicle connection points. Inspect adjoining clamps, fittings, and nearby hoses for wear before reassembly. This hose is listed for 2010-2012 Ford Fusion and 2010-2011 Mercury Milan reservoir to lower hose applications, so confirm the vehicle year and routing before ordering part number 19888.

Cross-reference part numbers include Febi-Bilstein 19888 and Unity Automotive 11571 for the same application.

Quality Assurance

Gates manufactures this molded hose as an OE-style replacement for vehicles that need a formed coolant hose profile. The EPDM construction and factory-molded shape support consistent fitment in the specified Ford Fusion and Mercury Milan applications.
