  • Constructed from durable EPDM material for heat and chemical resistance
  • Branched hose design with three different inside diameters for precise fitment
  • Protective sleeve included to enhance hose longevity
  • Complies with SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Compatible with Mercedes-Benz C230, C280, and C350 models

Detailed Product Description

The Dayco Curved Radiator Hose 73119 is a branched radiator coolant hose made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals. This hose features three distinct inside diameters—1 9/32 inches, 1 19/32 inches, and 7/8 inch—allowing it to connect multiple points within the cooling system efficiently. The outside diameters correspond accordingly to ensure a secure fit. A protective sleeve is integrated to guard against abrasion and premature wear, although this hose does not include a heat shield. The trunk height measures 17 1/2 inches, providing the necessary length for proper routing in the engine bay.

Dayco's Curved Radiator Hose product line focuses on delivering hoses with precise bends and branches to accommodate complex cooling system layouts. This hose line is designed to meet or exceed SAE standards, ensuring compatibility and durability for specific vehicle applications like the Mercedes-Benz C230, C280, and C350.

Common Applications and Problem Solving

  • Replacement of worn or cracked radiator coolant hoses in Mercedes-Benz C230, C280, and C350
  • Resolving coolant leaks caused by hose degradation or damage
  • Addressing overheating issues related to compromised coolant flow

  • Maintaining proper coolant circulation in branched cooling systems

Installation Notes and Tips

  • Verify compatibility with your specific Mercedes-Benz model before installation
  • Inspect all hose connections and clamps for wear and replace if necessary
  • Ensure the hose is routed without kinks or sharp bends to maintain coolant flow
  • Use appropriate coolant and follow manufacturer torque specifications for clamps
  • Check for leaks after installation and during initial engine operation
