Product Details

Dayco Curved Radiator Hose 71588 is a formed coolant hose used in radiator and engine-to-pipe plumbing where a straight hose will not follow the factory path. The EPDM material is selected for cooling-system duty, while the curved shape helps maintain proper routing in tight engine bays. This hose is listed for 2004-2006 Volkswagen Touareg upper engine-to-pipe use, plus lower radiator hose positions on the Chevrolet Tracker and Suzuki Vitara. The same part number also appears in cross-reference searches for ACDelco 24294L and 24355L, Gates 22046 and 22269, and NAPA 8729 and 9618.

What It Helps Address

• Coolant leaks from a cracked or aged radiator hose
• Softening, swelling, or collapse in an original hose
• Improper hose routing after cooling-system service
• Restricted coolant flow caused by hose deterioration
• Fitment issues when replacing a formed upper or lower hose

Installation Notes and Tips

Verify the hose position, end diameters, and routing before installation. Match the curved profile to the factory path and confirm clamp seating on clean, undamaged tube ends. Inspect adjacent cooling components, including clamps, thermostat housing connections, and pipe ends, for wear or corrosion before refilling the system.

Quality Assurance

This Dayco radiator coolant hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for cooling-system hose applications. Confirm vehicle fitment by year, make, model, and hose position before ordering.
