Product Details

Dayco 71271 is a formed radiator coolant hose for lower radiator routing where a curved shape is required. The EPDM rubber construction is suited for coolant circulation service, while the matched end diameters help maintain a proper connection at both ends. This hose is a practical replacement choice for Geo Metro, Pontiac Firefly, Suzuki Swift, Chevrolet Sprint, and Suzuki Forsa applications that use the specified lower hose configuration.

Common Cooling-System Issues It Can Address

• Cracked or split lower radiator hose
• Coolant leaks at the hose body or connection points
• Softening, swelling, or deterioration from age and heat
• Restricted coolant flow caused by a damaged hose
• Loss of proper hose routing on curved lower radiator runs

Installation Notes and Tips

Verify the hose shape, end diameters, and lower-position routing before installation. Inspect the radiator neck and engine-side connection points for corrosion, residue, or damage, and replace worn clamps as needed. Confirm fitment against the vehicle’s cooling-system layout for the exact model year and engine configuration listed.

Quality Assurance

Dayco manufactures cooling-system hoses to published SAE specifications, including SAE J20R4 Class D-1 and SAE J1684 Type EC, to support consistent material and dimensional standards.
