Product Details

The Dayco 81401 is a precision-molded flex radiator hose designed to replace both straight and molded radiator hoses across a wide range of engine applications. Measuring 2 inches in diameter by 9-1/2 inches in length, this lower position hose is sold individually and installs as a direct OE replacement.

Constructed with knitted reinforcement and synthetic EPDM rubber, this flex hose meets SAE J20R4, Class D-2 requirements — the industry standard for radiator and coolant hose performance. The EPDM compound resists splitting, ballooning, and elongation while standing up to ozone, environmental contaminants, engine coolants, and extreme temperature swings ranging from -40°F (-40°C) to +257°F (+125°C).

Key Features:

  • Precision-corrugated construction with an inserted helical steel coil spring for outstanding flexibility without flattening or collapsing
  • Knitted reinforcement and synthetic EPDM construction for long-lasting durability
  • Meets SAE J20R4, Class D-2 performance requirements
  • Rated for temperatures from -40°F to +257°F (-40°C to +125°C)
  • Resists ozone, coolants, and environmental elements
  • Designed to prevent splitting, ballooning, and elongation
  • OE replacement fit — no cutting or modifications required
  • Black finish; sold individually
  • Note: Not suitable for fuel or oil transfer

Dayco's flex radiator hose is the dependable, cost-effective solution for restoring proper coolant flow and preventing overheating. The corrugated, spring-reinforced design gives installers routing flexibility while maintaining a secure, leak-free connection.

Fast and easy

For the over-the-winter garage storage of my 911, the Rail Ramps Flatstopper product has eliminated the need to move the car over the winter in order to avoid the tires developing flat spots.
