Gates 24022 Radiator Coolant Hose

Gates Straight Coolant Hose for OE-Style Repairs

Gates 24022 is a straight radiator coolant hose built for straight coolant or air connections in automotive, stationary engine, industrial, and home applications. Made from EPDM with a 2-ply construction, it is sized for a 1.375 in. inside diameter at both ends and a 3 ft. centerline length for cut-to-length use.

For service work on vehicles such as the Nissan Pathfinder, INFINITI Q45, and Chevrolet Corvette, this Gates Straight Coolant Hose (Standard) provides a straightforward replacement option where a straight hose section is required. The Gates 24022 is also referenced by cross numbers including Dayco 76138 and Continental 56022 for the same application.

Key Features

• EPDM rubber construction for coolant and air routing
• 2-ply hose design for added reinforcement
• 1.375 in. inside diameter on both ends
• 3 ft. centerline length for cut-to-length installation
• 65 psi working pressure rating
• Straight hose design for direct pipe-to-pipe or pipe-to-thermostat connections

Product Details

The Gates Straight Coolant Hose line is built for standard straight-run connections where molded bends are not required. This hose is intended for applications that need a clean, direct coolant path, including pipe to thermostat, engine to pipe, water pump to pipe, and radiator to valve routing. With EPDM material and a 2-ply build, Gates 24022 is suited to replacement work that calls for a durable straight hose section rather than a formed hose shape.

Compatible vehicle applications include 2001-2004 Nissan Pathfinder, pipe to thermostat; 1997-2001 INFINITI Q45, upper tee-1 to pipe-2 and lower pipe-1 to water pump; and 1990-1995 Chevrolet Corvette, lower radiator to valve. The part number 24022 is also used across additional fitments such as 1991-1996 INFINITI G20, 1994-1997 Nissan Pickup, and 1993-1996 Toyota Corolla.

Common Uses

• Replacing a cracked or hardened straight coolant hose
• Restoring coolant flow between pipe, thermostat, water pump, or radiator connections
• Repairing leaks at straight hose sections in the cooling system
• Servicing cut-to-length hose applications on Nissan, INFINITI, Toyota, and Chevrolet models
• Addressing hose deterioration from heat, age, or pressure cycling

Installation Notes and Tips

Measure the required hose length before cutting, and confirm the inside diameter matches the connection points. This straight hose is not molded, so it should be trimmed to the exact length needed for the vehicle application. Verify routing, clamp placement, and clearance before final tightening. For fitment-specific service, use the vehicle position notes listed for applications such as 2001-2004 Nissan Pathfinder, 1997-2001 INFINITI Q45, and 1990-1995 Chevrolet Corvette.
