Detailed Product Description

The Dayco Curved Radiator Hose 72869 is engineered as a branched hose with three distinct inside diameters: 1 3/4 inches, 1 13/16 inches, and 1 3/8 inches, allowing it to connect multiple points within the cooling system efficiently. The outside diameters correspond accordingly to ensure a secure fit. Manufactured from EPDM, this hose offers excellent resistance to heat, ozone, and coolant chemicals, which is critical for maintaining engine cooling system integrity. The hose does not include a heat shield or protective sleeve but meets SAE J20R4 Class D-1 and SAE J1684 Type EC standards, ensuring it meets industry requirements for coolant hoses.

Curved Radiator Hose Product Line

The Dayco Curved Radiator Hose product line focuses on delivering hoses with specific bends and branches to accommodate complex cooling system layouts. This line is designed to provide precise fitment and reliable coolant flow in applications where straight hoses are insufficient. The 72869 part exemplifies this with its branched design and multiple diameter ends, tailored for Ram heavy-duty trucks.

Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses in Ram 2500 and 3500 vehicles
• Prevention of coolant leaks caused by hose degradation or improper fit
• Maintaining optimal engine temperature by ensuring proper coolant circulation
• Addressing cooling system failures related to hose collapse or swelling
• Supporting complex cooling system layouts requiring branched hose configurations

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to avoid burns. Verify the hose ends match the specified inside diameters (1 3/4", 1 13/16", and 1 3/8") for proper fitment. 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.
