Product Details

This Dayco Curved Radiator Hose, part number 72918, is engineered as a lower radiator coolant hose for 2013-2018 Lexus ES300h, 2013-2018 Toyota Avalon, and 2012-2017 Toyota Camry. The hose uses EPDM rubber for coolant exposure and heat cycling, with matching 1 5/16 in. inside diameters at both ends and 1 11/16 in. outside diameters.

For buyers searching for a lower radiator hose for Toyota Camry, Toyota Avalon, or Lexus ES300h, this line helps narrow the selection to the correct curved configuration and size.

Common Cooling System Issues Addressed

• Cracked or aged lower radiator hose material

• Softening, swelling, or deterioration from heat and coolant exposure
• Fitment mismatch when replacing the lower hose on Toyota Camry, Toyota Avalon, or Lexus ES300h

Installation Notes and Tips

Verify the lower hose routing, end diameters, and vehicle application before installation. Inspect the radiator neck, engine connection points, and clamps for wear or corrosion before installing Dayco 72918. Confirm the hose is positioned without twist or kinks so coolant flow and clearance match the original layout.
