Product Details

The Gates 23038 radiator coolant hose is engineered for vehicles that require a formed lower hose with the correct bends and dimensions. Its molded profile helps maintain the factory hose routing on the Jeep Grand Cherokee and Jeep Commander cooling system, while the EPDM material is suited for standard coolant exposure and underhood temperatures. If you are replacing a worn or leaking lower hose, Gates 23038 provides a direct-fit service part for these applications.

This part cross-references Dayco 72223 for the same application.

Common Replacement Uses

• Coolant leaks from a cracked or softened lower hose
• Collapsed or distorted hose shape affecting coolant flow
• Heat-related hose deterioration near the radiator circuit
• Service replacement for a damaged molded hose on Jeep cooling systems
• Restoring proper lower hose routing on the radiator circuit

Installation Notes

Verify hose routing, end diameters, and centerline length before installation. Drain coolant as needed, inspect adjoining necks and clamps for wear, and confirm the hose is seated without twist or tension. For best results, replace the hose when the engine is cool and refill the cooling system according to the vehicle service procedure.

Quality Assurance

Gates manufactures molded coolant hoses to OEM-quality specifications for replacement use. The 23038 is built as a molded EPDM hose for the listed Jeep applications and is backed by Gates product engineering standards.
