Detailed Description

Dayco 72236 is a molded lower radiator hose engineered for vehicles that need a curved hose path between cooling-system connections. Its EPDM material is suited for coolant exposure, while the dual I.D. design helps match the different connection sizes used in the application. For Chrysler Aspen and Dodge Durango cooling-system service, this hose supports the correct routing and fit required for replacement work.

This part cross-references Gates 22897 for the same application. If you are replacing a worn lower radiator hose on a 2007-2008 Chrysler Aspen or a 2004-2008 Dodge Durango, Dayco 72236 gives you the specified dimensions and curved shape needed for the job.

Common Problems This Hose Can Address

• Cracked or split lower radiator hose
• Coolant leaks at the hose connection points
• Softening, swelling, or deterioration from heat and coolant exposure
• Poor hose routing caused by an incorrect replacement hose
• Cooling-system service on Chrysler Aspen and Dodge Durango models with the listed fitment

Installation Notes and Tips

Verify the end inside diameters and hose routing before installation to confirm the correct lower hose match. Inspect the radiator necks, clamps, and adjoining coolant passages for wear or corrosion before installing the new hose. After installation, refill the cooling system with the proper coolant and check for leaks at operating temperature.
