Gates 18867 HVAC Heater Hose - Heater To Engine or Heater To Intake Manifold

Gates 18867 Molded Heater Hose Overview

The Gates 18867 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a formed routing path is required. It is made from EPDM and measures 16 mm (0.62 in) inside diameter at both ends with a 483 mm (19 in) centerline length.

Compatible with select Chevrolet Corsica, Chevrolet Cavalier, and Pontiac Tempest heater hose applications, this Gates molded heater hose supports coolant, water, and air transfer. It is also approved for marine use, making it a practical replacement for formed hose routing in demanding service conditions.

Detailed Product Description

Gates 18867 is a molded heater hose designed to match the formed routing used in smaller engine compartments. The molded profile helps the hose follow the original path between the heater circuit and engine or intake manifold, which is important on vehicles such as the Chevrolet Cavalier, Chevrolet Corsica, and Pontiac Tempest. As a Gates Molded Heater Hose, part number 18867, it provides a direct replacement format for applications that require a shaped hose rather than a straight length.

This hose uses EPDM material for service in coolant systems and other fluid or air transfer applications. The 16 mm inside diameter at both ends and 19-inch centerline length make it a fitment-specific replacement for the listed heater-to-engine and heater-to-intake-manifold positions.

This part cross-references Four Seasons 63070 for the same application.

Common Uses

• Replacing a cracked or softened heater hose
• Restoring coolant flow between the heater circuit and engine
• Correcting a hose that no longer follows the original molded route
• Addressing coolant seepage at a formed hose section
• Replacing a hose with heat-related swelling or collapse

Installation Notes and Tips

Verify the hose routing, end inside diameter, and centerline length before installation. This molded hose is listed for 1990-1994 Chevrolet Cavalier heater to engine, 1992-1996 Chevrolet Corsica heater to engine, 1990-1991 Chevrolet Corsica heater to intake manifold, and 1990-1991 Pontiac Tempest heater to intake manifold applications. Confirm the hose follows the original formed path and inspect adjoining clamps, fittings, and connection points for wear before service.

Quality Assurance
