Detailed Description

This Gates 22493 radiator coolant hose is engineered for vehicles that require a molded hose shape to maintain correct coolant flow and hose routing. The EPDM material is suited for engine cooling service, while the molded design helps match the original hose path and connection sizes. It is a practical replacement for service work on the Chevrolet Impala upper radiator hose application, the Chevrolet Monte Carlo upper coolant hose application, and the Toyota Tundra lower coolant hose application.

For fitment-based searches, this part is commonly referenced as a molded coolant hose for 2006-2011 Chevrolet Impala upper radiator and HVAC-compatible coolant/heater hose applications, 2006-2007 Chevrolet Monte Carlo upper hose applications, and 2000-2004 Toyota Tundra lower hose applications. Gates 22493 also cross-references Dayco 72115 for the same application.

What It Helps Fix

• Coolant leaks from a cracked or aged molded hose
• Softening, swelling, or collapse in the original hose
• Poor hose routing after cooling-system repair
• Loss of coolant flow caused by a damaged radiator hose
• Service delays when an OE-style molded replacement is needed

Installation Notes and Tips

Verify end diameters, centerline length, and hose routing before installation. Confirm whether the vehicle uses the upper or lower hose position, and compare the original hose shape to the molded profile of Gates 22493. Inspect clamps, necks, and adjoining cooling-system components for wear before reassembly.
