Gates 18202 HVAC Heater Hose

Gates Molded Heater Hose 18202 Overview

The Gates 18202 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. Made from EPDM, it is shaped for direct routing in coolant, water, and air applications and is also approved for marine use.

Gates Molded Heater Hose line products are factory-molded to match the routing needs of modern engines, helping maintain proper hose alignment in compact spaces. This makes the 18202 a practical choice for service on vehicles such as Honda Civic, Nissan Sentra, and Mazda 626 applications that use a molded heater hose layout.

Detailed Description

The Gates 18202 molded heater hose is built for vehicles that require a formed hose to connect heater, throttle body, intake manifold, or pipe locations without kinking or forcing the hose into place. Its molded shape supports proper routing in smaller, tighter-fitting engine compartments, and the EPDM material is commonly used in cooling-system service for heat and fluid resistance. This part number 18202 is listed across a wide range of import applications, including Honda Civic, Nissan Sentra, and Mazda 626 fitments.

This part cross-references Bosch 18202 for the same application.

What This Hose Helps Address

• Cracked or hardened molded heater hose sections
• Coolant leaks at formed hose routing points
• Poor hose fitment in compact engine bays
• Kinking caused by using a straight hose where a molded hose is required
• Service replacement for throttle body, intake manifold, or pipe connections

Installation Notes and Tips

• Verify end inside diameter and centerline length before installation.
• Match the hose routing to the original molded path for proper clearance.
• Inspect adjoining clamps, pipes, and fittings for wear or corrosion before reuse.
• Confirm the hose is routed away from moving parts and hot exhaust surfaces.
• Use the vehicle-specific fitment listing to confirm the correct application for your engine layout.

Quality Assurance

Gates molded heater hoses are factory-shaped for OE-style routing and built from EPDM for cooling-system service. The 18202 is listed for multiple import applications, including 1992-1995 Honda Civic, 1998-1999 Nissan Sentra, and 1990-1992 Mazda 626 fitments.
