Detailed Description

Gates 21533 is part of the Molded Coolant Hose product line, which covers a wide range of replacement coolant hose applications with OEM-quality specifications. This hose is shaped for vehicles that require a formed connection rather than a straight universal hose, helping maintain the original coolant path on the engine, radiator, thermostat, or tee connection. It is listed for applications including 2008-2010 Chevrolet Malibu lower rear, 2007-2009 Saturn Aura lower rear, 2002-2006 Volkswagen Golf upper radiator to tee-1, 1999-2005 Volkswagen Beetle upper tee-to-tee routing, and 1995-1998 Nissan 200SX pipe to engine.

This part cross-references Dayco 71356 and Continental 66514 for the same application. Use Gates 21533 when you need a molded coolant hose with the correct diameter, length, and routing profile for the vehicle listed in the fitment data.

Common Problems This Hose Can Address

• Cracked or split coolant hose sections
• Coolant leaks at molded hose bends or connection points
• Collapsed or softened hose material from age and heat
• Incorrect hose routing after a previous repair
• Replacement needs for radiator, heater, or thermostat hose paths

Installation Notes and Tips

Verify the vehicle’s hose routing, end diameters, and connection style before installation. Some listed applications note cut-to-fit use or non-exact duplicate routing, so compare the original hose shape and length to the replacement before trimming or installing. Confirm that the hose is positioned correctly at the radiator, thermostat, tee, or engine connection points to avoid kinks and coolant flow restriction.
