Detailed Description

Gates 22453 is a molded radiator coolant hose built to match the routing and dimensions required for the lower radiator-to-pipe connection on the INFINITI Q45. The molded profile helps maintain proper hose alignment in the cooling system, while the EPDM material is commonly used in coolant applications for heat and fluid resistance. If you are replacing a worn or leaking hose on a 1997-2001 INFINITI Q45, this part provides the correct shape and sizing for the specified position.

This part cross-references Anchor 9086 for the same application. Gates 22453 is also listed under interchange references 22358M and 215036P000/215036P001.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged lower radiator hose
• Softening, swelling, or collapse of the original hose
• Improper hose routing after prior cooling-system repair
• Loss of coolant from a damaged radiator-to-pipe connection
• Service issues caused by a hose that no longer holds its molded shape

Installation Notes and Tips

Verify the hose position before installation: this part is for the lower radiator-to-pipe-1 location on 1997-2001 INFINITI Q45 models. Inspect adjoining pipes, clamps, and coolant passages for wear or corrosion before installing the new hose. Drain coolant as needed, route the hose without twisting, and confirm that the hose seats fully at both ends before refilling and bleeding the cooling system.

Quality Assurance

Gates manufactures molded coolant hoses to OEM-quality specifications for replacement cooling-system service. The Gates 22453 part is built to match the application dimensions and molded configuration required for the listed INFINITI Q45 fitment.
