Detailed Description

Gates 21065 is a molded radiator coolant hose designed for lower cooling-system routing where a shaped hose is required to match factory-style bends and clearances. The EPDM construction is suited for coolant service, while the molded profile helps maintain the correct path between connection points. This part number is listed across a broad range of import and domestic applications, including 1983-1989 Mitsubishi Mighty Max, 1981-1984 Nissan Maxima, 1983-1988 Toyota Cressida, and 2001-2002 Mazda Millenia lower hose applications. The 21065 designation is also referenced in multiple interchange listings for cross-checking during parts lookup.

This part cross-references Dayco 70756 and FEL-PRO 61236 for the same application.

What It Is Used For

• Replacing a cracked or leaking lower radiator hose
• Restoring coolant flow in a molded hose routing
• Addressing hose collapse, swelling, or soft spots from age
• Correcting fitment on vehicles that require a formed lower hose shape
• Servicing cooling-system repairs on Mazda Millenia, Mitsubishi Galant, and Toyota Cressida applications

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Some listed applications note cut-to-fit or vehicle-specific cooling-system requirements, so compare the original hose shape and connection points before final assembly. Confirm whether the vehicle is equipped with air conditioning or standard cooling where the fitment notes specify those conditions.
