Detailed Product Description

This Gates molded coolant hose, part number 22646, is built for upper radiator hose service where a formed hose is required to follow the original engine bay routing. The molded design helps match the OE hose path on 2001-2011 Ford Ranger, 2001-2010 Mazda B4000, and select Ford Explorer, Explorer Sport, and Explorer Sport Trac applications. If you are replacing a worn upper radiator hose on a Ford Ranger or Mazda B4000, Gates 22646 provides a fit-focused replacement built around the original dimensions.

As part of the Gates Molded Coolant Hose line, this hose is intended for radiator hose replacement work where accurate shape and material selection matter. The EPDM construction supports coolant exposure, while the molded profile helps simplify replacement on vehicles that require a formed upper hose rather than a universal straight hose.

This part cross-references Continental 62821 for the same application.

What It Helps Address

• Coolant leaks from a cracked or aged upper radiator hose
• Softening, swelling, or collapse of the original hose
• Improper hose routing after prior repair work
• Loss of coolant from a deteriorated molded hose section
• Fitment issues when a formed replacement hose is required

Installation Notes and Tips

• Verify the vehicle’s year, make, model, and hose position before ordering.
• Confirm the hose path matches the upper radiator routing on the application.
• Inspect hose clamps, necks, and adjoining coolant components during replacement.
• Check for coolant residue or hardened hose material that indicates system wear.
• For 2001 Ford Explorer Sport and 2001 Ford Explorer Sport Trac, confirm the Jul. 25, 2000 and newer note before installation.
