Product Details
This Dayco curved radiator hose is engineered for lower coolant transfer where a formed hose is required. The 72338 hose matches applications that need a 1 5/16 in. inside diameter at both ends and a curved profile for proper routing between the engine tee and radiator or lower radiator connection. It is compatible with 2006-2007 Chevrolet Cobalt, lower - tee to radiator; 2007 Pontiac G5, lower - tee to radiator; 2006 Pontiac Pursuit, lower - tee to radiator; and 2003-2005 Mitsubishi Lancer, lower. This part cross-references ACDelco 24581L and Gates 23165 for the same application.
What It Helps Address
- Coolant leaks from a cracked or softened lower radiator hose
- Restricted coolant flow caused by hose collapse or internal deterioration
- Improper hose routing on curved lower radiator connections
- Heat-related wear in exposed hose sections
- Fitment issues when replacing an OE-style formed coolant hose
Installation Notes
Verify hose routing, end diameters, and connection points before installation. Inspect clamps, radiator necks, and tee fittings for wear or corrosion before transferring the hose into service. Confirm the hose follows the original curved path without twisting so coolant flow and clearance remain correct.
Quality Assurance
Dayco manufactures this radiator coolant hose to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and performance standards for cooling-system service.
