Product Details

This Dayco Curved Radiator Hose is engineered as an upper radiator coolant hose for vehicles that use a formed hose shape to connect the engine cooling circuit. The EPDM rubber construction is suited for coolant exposure, while the matched end diameters and curved profile help it follow the original routing used on the vehicle.

Compatible With 2014-2016 Toyota Highlander, upper; 2011-2016 Toyota Sienna, upper; 2010-2015 Lexus RX350, upper; and 2010-2015 Lexus RX450h, upper. This part number, 72529, is also referenced by several aftermarket and OE cross numbers for the same cooling-system application.

Common Cooling Issues This Hose Can Address

  • Cracked or split upper radiator hose material
  • Coolant seepage at the hose connection points
  • Softening, swelling, or heat-related hose deterioration
  • Loss of proper hose shape after age and mileage
  • Cooling-system service on a worn factory-style upper hose

Installation Notes

Inspect the mating necks, clamps, and surrounding cooling components before installation.

After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.
