Detailed Description

This radiator coolant hose is shaped for curved routing in the upper cooling circuit, helping maintain the factory hose path on supported vehicles. The EPDM rubber construction is commonly used in coolant applications because it is formulated for heat and fluid exposure in the engine bay. Dayco 71482 is a practical OE-style replacement for vehicles that require a formed upper hose with matching end diameters and routing geometry.

This part cross-references Gates 22822 for the same application. It is a direct-fit style option for Chevrolet Malibu, Pontiac G6, Jaguar XJ12, and Jaguar XJS cooling system service where the listed hose configuration matches the vehicle.

What It Helps Address

• Cracked or aged upper radiator hose material
• Coolant leaks at the hose body or ends
• Improper hose routing from a previous replacement
• Softening or swelling from heat and coolant exposure
• Cooling system service on vehicles with formed hose routing

Installation Notes and Tips

• Verify the hose path, end diameters, and position before installation.
• Inspect hose necks, clamps, and adjacent cooling components for wear or corrosion.
• Confirm the hose is routed without twist or tension so it follows the factory curve.
• Replace coolant and bleed the system according to the vehicle service procedure after installation.

Quality Assurance

Dayco 71482 is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator hose applications. The Dayco Curved Radiator Hose line is built for formed cooling-system replacement where correct routing and material specification matter.
