Product Details

Dayco’s Curved Radiator Hose line focuses on formed coolant hoses that follow factory-style routing and fitment. Part number 71927 is made for upper radiator hose service on 1996-2000 Toyota RAV4 models, where a curved profile and consistent end sizing help match the original cooling system layout. The EPDM rubber construction is suited for coolant exposure, while the protective sleeve adds an extra layer where routing passes near heat or abrasion points.

This part cross-references Toyota OE numbers 16571-74310 and 16571-74400 for the same application.

Common Cooling System Issues

  • Cracked or split upper radiator hose
  • Coolant leaks at the hose connection points
  • Softening, swelling, or deterioration from age and heat
  • Improper hose routing after a failed replacement
  • Restricted cooling system flow caused by a damaged hose

Installation Notes and Tips

Inspect the hose necks, clamps, and adjacent cooling components before installation. Confirm the hose routing matches the upper position on the Toyota RAV4 and verify the 1 3/16-inch end sizes before assembly. After installation, refill the cooling system with the correct coolant and check for leaks once the engine reaches operating temperature.

Quality Assurance
