Dayco 72369 Radiator Coolant Hose - Lower

Dayco 72369 Curved Radiator Hose Overview

Dayco 72369 is a curved radiator coolant hose for the lower cooling circuit on select Chevrolet Malibu, Pontiac G6, and Saturn Aura applications. Built from EPDM and finished in black, it is shaped for the routing needed in these vehicles and includes a protective sleeve for added abrasion resistance in exposed areas.

The Dayco Curved Radiator Hose line focuses on application-specific hose geometry and OE-style cooling system service. Part number 72369 follows that approach with a single I.D. hose design, matching 1 5/16-inch inside diameters at both ends for a direct replacement in the listed lower radiator hose positions.

Detailed Description

Dayco 72369 radiator coolant hose is engineered for lower radiator hose replacement on 2006-2010 Chevrolet Malibu, 2006-2010 Pontiac G6, and 2007-2008 Saturn Aura models. The curved profile supports the factory hose path, while the EPDM material is suited for coolant exposure and everyday underhood temperatures. The protective sleeve adds an extra layer where the hose may contact nearby components.

This part cross-references Gates 23124 for the same application. If you are searching for a lower radiator hose for a Chevrolet Malibu, Pontiac G6, or Saturn Aura, Dayco 72369 provides the correct fitment details and hose dimensions for those listed vehicles.

Common Cooling System Issues Addressed

• Cracked or aged lower radiator hose material
• Coolant seepage at the hose connection points
• Incorrect hose routing on replacement service
• Chafing where the hose passes near adjacent components
• Loss of cooling system integrity from a worn hose

Installation Notes and Tips

Verify the vehicle year, make, model, and lower hose routing before installation. Confirm the 1 5/16-inch end diameters match the original hose connections and inspect clamps, necks, and nearby components for wear or corrosion before reassembly. Proper routing is important to keep the curved hose aligned with the factory path and away from heat or abrasion points.

Quality Assurance

Dayco manufactures cooling system hoses to published SAE specifications, including SAE J20R4 Class D-1 and SAE J1684 Type EC for this part. That specification-based construction supports consistent fit and material performance for the listed Chevrolet Malibu, Pontiac G6, and Saturn Aura applications.
