Gates 18289 HVAC Heater Hose - Reservoir To Engine

Gates 18289 Molded Heater Hose Overview

The Gates 18289 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a formed routing path matters. It is made from EPDM and uses a factory-molded shape with 0.34 in. inside diameter ends and a 15.3 in. centerline length for a precise reservoir-to-engine connection.

Compatible with 2002-2005 Chevrolet Cavalier and 2002-2005 Pontiac Sunfire reservoir to engine applications, this molded heater hose supports coolant, water, and air service. Gates 18289 is also approved for marine applications and is part of the Gates Molded Heater Hose line for small I.D. hose routing needs.

Detailed Description

Gates 18289 is a molded HVAC heater hose engineered to match the routing needs of compact engine compartments. Its OEM-style formed design helps maintain the correct hose path between the reservoir and engine on 2002-2005 Chevrolet Cavalier and 2002-2005 Pontiac Sunfire models. The EPDM material is commonly used in cooling-system service for its resistance to heat and fluid exposure.

This part cross-references Dayco 87007 for the same application. If you are replacing a worn, cracked, or collapsed reservoir-to-engine hose, Gates 18289 provides the molded profile and small inside diameter needed for a direct-fit repair on Chevrolet Cavalier and Pontiac Sunfire applications.

Common Problems This Hose Can Address

• Coolant seepage from an aged heater hose
• Cracking or hardening from heat cycling
• Improper hose routing in a tight engine compartment
• Restricted coolant flow caused by a collapsed hose
• Fitment issues when a straight hose will not follow the original path

Installation Notes and Tips

Verify the reservoir-to-engine routing before installation and compare the hose shape, end diameters, and centerline length to the original part. Inspect adjoining fittings and clamps for wear, and confirm the cooling system is properly drained and refilled according to the vehicle service procedure. For best results, install on a cool engine and check for leaks after the system is returned to operating temperature.

Quality Assurance

Gates manufactures this molded heater hose as an OEM-style replacement for applications that require accurate formed routing and dependable material selection. Gates 18289 is built to match the fitment needs of the listed Chevrolet Cavalier and Pontiac Sunfire applications.
