Gates 18958 HVAC Heater Hose - Heater To Pipe-2

Overview

Gates 18958 is a molded HVAC heater hose built in an OEM-style shape for tight engine compartments. It uses EPDM construction and a factory-molded profile to support coolant, water, and air routing where a formed hose is required.

Key Features

• EPDM construction for heat and fluid resistance in HVAC and cooling service.
• Molded design follows the original hose path for a cleaner, more accurate routing.
• Small inside diameters of 16 mm and 19 mm for the specified connection points.
• 15.1-inch centerline length for the listed molded application.
• Gates Molded Heater Hose line for formed replacement hose applications.

Detailed Description

This Gates heater hose is engineered as a molded replacement for compact routing needs in HVAC and coolant systems. The formed shape helps maintain the intended hose path in confined spaces, while the EPDM material is suited for coolant, water, and air transfer. It is a direct fit for the listed applications on Acura SLX and Isuzu Trooper models, including Fits 1996-1997 Acura SLX, Heater To Pipe-2 and Fits 1992-1997 Isuzu Trooper, Heater To Pipe-2. This part cross-references Four Seasons 18958 for the same application.

Common Uses

• Replacing a cracked or hardened heater hose.
• Restoring coolant flow through a molded HVAC hose route.
• Correcting leaks at formed hose connection points.
• Replacing a hose that no longer holds its original shape.

Installation Notes

Verify the hose routing, inside diameters, and centerline length against the removed part before installation. Confirm the molded shape matches the vehicle’s heater-to-pipe routing and inspect adjoining fittings for wear or corrosion.

Quality Assurance

Gates manufactures this molded hose as an OEM-style replacement for formed hose applications and compact engine bays.
