Detailed Description

Gates 23338 is a molded radiator coolant hose designed for lower hose applications where the factory routing requires a formed shape rather than a straight hose. The EPDM material is commonly used in cooling system service for its resistance to heat and coolant exposure. This hose is listed for 2008-2012 Chevrolet Malibu, lower; 2007-2009 Pontiac G6, lower; and 2007-2009 Saturn Aura, lower. If you are replacing a worn lower radiator hose on a Chevrolet Malibu, Pontiac G6, or Saturn Aura, this part number provides an OE-style service solution.

This part cross-references Dayco 72400 for the same application.

Common Repair Uses

• Coolant leaks from a cracked or aged lower radiator hose

• Loss of coolant from hose-end seepage
• Improper hose routing after prior repair work
• Cooling system service on a Chevrolet Malibu, Pontiac G6, or Saturn Aura

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Inspect hose clamps, thermostat housing connections, radiator necks, and adjacent cooling system components for wear or corrosion before fitting Gates 23338. Confirm the vehicle is a lower hose application and compare the removed hose to the replacement part number 23338 before final assembly.
