Gates 19287 HVAC Heater Hose - Engine To Heater or Heater To Pipe-2

Gates Molded Heater Hose 19287 Overview

Gates 19287 is a molded heater hose built for tight engine bays where a factory-shaped coolant hose is needed for a clean, OE-style routing. Made from EPDM, it is specified for coolant, water, and air service and is approved for marine applications.

This Gates Molded Heater Hose line is engineered for smaller-diameter hose routing in modern vehicles, helping maintain proper flow and fit in confined spaces. For Buick Rendezvous, Pontiac Aztek, and Pontiac Montana applications, the molded shape supports direct replacement of the original hose path.

Key Features

• EPDM construction for heater and coolant service
• Factory-molded profile for tighter engine compartments
• OE-style routing for cleaner hose placement
• Approved for coolant, water, air, and marine applications
• End sizes: 16 mm (0.64 in) and 19 mm (0.75 in)
• Centerline length: 564 mm (22.2 in)

Product Details

The Gates Molded Heater Hose 19287 is a molded coolant hose designed around the demands of compact engine layouts. Its EPDM material and formed shape help it follow the original hose path on vehicles that require a small I.D. molded hose. This part cross-references Dayco 88425 for the same application.

Compatible With 2002-2005 Buick Rendezvous, Heater To Pipe-2; 2001-2005 Pontiac Aztek, Heater To Pipe-2; and 2005 Pontiac Montana, Engine To Heater. For Pontiac Aztek heater hose replacement and Buick Rendezvous heater-to-pipe routing, Gates 19287 provides the molded configuration needed for proper fitment.

Common Uses

• Replacing a cracked or leaking heater hose
• Restoring coolant flow through the heater circuit
• Correcting hose routing in tight engine compartments
• Addressing soft, swollen, or heat-aged EPDM hose sections
• Servicing molded hose paths on Pontiac Montana and Pontiac Aztek applications

Installation Notes

Verify end diameters and centerline length before installation to confirm the hose matches the original routing. On the 2005 Pontiac Montana, the note indicates cut-to-fit use for vehicles without an auxiliary heater, so confirm the vehicle’s heater configuration before ordering. Inspect adjoining pipes, clamps, and connection points for wear before installing the new hose.

Quality Assurance

Gates is known for OE-style hose construction and molded replacement parts that follow factory routing requirements. Part number 19287 is built to match the shape and dimensions needed for listed Buick and Pontiac heater hose applications.
