Detailed Product Features and Specifications

The Dayco Curved Radiator Hose line focuses on delivering precise fitment and durability for radiator coolant systems. This particular hose, part number 71497, is a branched hose constructed from EPDM (ethylene propylene diene monomer) rubber, known for its excellent resistance to heat, ozone, and coolant chemicals. The hose features three distinct inside diameters—1 3/16 inches, 1 11/32 inches, and 3/8 inches—allowing it to connect multiple points within the cooling system efficiently. It does not include a heat shield or protective sleeve, which is typical for this type of radiator hose. The trunk height measures 14 inches, providing the necessary length for proper routing in compatible Volvo models.

Compatible Volvo Models and Applications

This radiator coolant hose is specifically compatible with Volvo 740, 760, 780, and 940 models. It is designed to replace original equipment hoses that require a branched configuration with the specified diameters. Using the Dayco 71497 hose helps maintain proper coolant flow and system integrity in these vehicles.

  • Replaces worn or cracked radiator coolant hoses in Volvo 740, 760, 780, and 940
  • Addresses coolant leaks caused by hose degradation or damage
  • Prevents overheating due to compromised coolant circulation
  • Restores proper coolant routing in branched hose systems
  • Eliminates coolant contamination from hose failure

Installation Notes and Tips

When installing the Dayco Curved Radiator Hose 71497, ensure the vehicle is cool and the cooling system is depressurized. Verify the hose diameters match the connection points on your Volvo model. Use appropriate clamps to secure the hose ends and check for leaks after installation. Avoid twisting or stretching the hose during installation to maintain its integrity.
