Gates 22276 Radiator Coolant Hose - Lower - Engine To Pipe

Gates 22276 Molded Coolant Hose Overview

The Gates 22276 molded coolant hose is an OE-style radiator coolant hose built for lower engine-to-pipe routing. Made from EPDM, it is shaped to match the factory path and dimensions needed for a clean replacement on select Nissan and INFINITI cooling systems.

Gates Molded Coolant Hose products are built for upper, lower, bypass, heater, and other coolant applications using OEM-quality specifications. This line is designed to simplify radiator hose replacement on vehicles that require a formed hose rather than a universal straight hose.

Key Features

• EPDM construction for coolant-system service
• Molded shape for lower engine-to-pipe routing
• 1.58 in. inside diameter at both ends
• 4.8 in. centerline length
• No spring and no quick-connect fittings
• Direct replacement style for select factory cooling layouts

Detailed Product Description

Gates part number 22276 is a molded radiator coolant hose engineered for vehicles that use a formed lower hose between the engine and pipe. The hose measures 1.58 inches inside diameter at each end and 4.8 inches centerline length, with molded construction that follows the original routing more closely than a universal hose. It is listed for 1996-2000 Nissan Pathfinder, lower - engine to pipe, and 1997-2000 INFINITI QX4, lower - engine to pipe. If you are replacing a worn Nissan Pathfinder lower radiator hose or an INFINITI QX4 lower coolant hose, Gates 22276 provides the correct molded profile for those applications.

This part cross-references Continental 62457 for the same application.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or softened lower hose
• Collapsed hose sections caused by age and heat cycling
• Poor fitment from a straight universal hose on a formed routing
• Cooling-system service on a Nissan Pathfinder or INFINITI QX4
• Replacement of a deteriorated lower engine-to-pipe coolant connection

Installation Notes and Tips

Verify the hose routing, end diameters, and molded shape against the original part before installation. Inspect adjoining pipes, clamps, and sealing surfaces for corrosion or damage, and replace any worn components as needed. Confirm the vehicle is listed as 1996-2000 Nissan Pathfinder or 1997-2000 INFINITI QX4 with lower engine-to-pipe routing before ordering.
