Dayco Curved Radiator Hose Product Line Details

The Curved Radiator Hose line by Dayco focuses on delivering hoses shaped to fit specific radiator and engine configurations. This product line emphasizes proper curvature to maintain coolant flow efficiency and reduce stress on hose connections. The 72313 part number is part of this line, tailored to meet the cooling system requirements of certain Audi and Mazda models.

Technical Description and Compatibility

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, making it suitable for automotive cooling systems. Both ends of the hose have an inside diameter of 1 7/32 inches, ensuring a consistent seal and fit. The hose does not include a heat shield or protective sleeve, which is typical for applications where additional protection is not required. It meets SAE J20R4 Class D-1 and SAE J1684 Type EC standards, confirming its compliance with industry requirements for coolant hoses.

The Dayco 72313 hose is compatible with various Audi models including A4, A4 allroad, A4 Quattro, A5, A5 Quattro, and allroad variants, as well as Mazda 3, 3 Sport, and 5 models. This ensures proper fitment and reliable operation within these vehicles' cooling systems.

Common Applications and Problem Solving

  • Replacement of worn or cracked radiator coolant hoses in Audi A4 and A5 series
  • Addressing coolant leaks caused by hose degradation in Mazda 3 and 5 models
  • Restoring proper coolant flow to prevent engine overheating
  • Eliminating hose collapse or swelling under pressure
  • Maintaining cooling system integrity in vehicles requiring a curved radiator hose

Installation Notes and Tips

Ensure the engine is cool before removing the old radiator hose to avoid burns. Verify that the hose diameter and length match the original equipment specifications. Use appropriate clamps to secure the hose ends and check for leaks after installation. The absence of a heat shield or protective sleeve means extra care should be taken to avoid contact with sharp edges or hot components during installation.
