Common Cooling Issues This Hose Can Address

• Cracked or split lower radiator hose
• Coolant leaks at the hose body or ends
• Softening, swelling, or collapse from age and heat
• Incorrect hose routing after a previous replacement
• Loss of coolant flow caused by a deteriorated hose

Installation Notes and Tips

Verify the hose shape, end diameters, and centerline length against the original part before installation. Confirm lower-position routing on the vehicle and inspect the radiator neck, engine outlet, and clamps for wear or corrosion before installing the new hose. For best results, replace coolant with the correct specification after the system is serviced and bleed air from the cooling system according to the vehicle procedure.

Gates manufactures molded coolant hoses to OEM-quality specifications for replacement cooling-system service. The 20537 is built as a formed EPDM hose for the listed Jeep applications and follows the Gates molded hose product-line approach for fit and routing accuracy.
