About the Molded Coolant Hose Product Line

The Gates Molded Coolant Hose line features hoses specifically designed with molded shapes to match OEM specifications. This ensures a precise fit and reduces the risk of leaks or improper installation. The molded construction of the 23605 hose provides consistent performance and durability, making it suitable for demanding cooling system applications in Dodge Ram trucks.

Detailed Product Description

The Gates Molded Coolant Hose 23605 is a radiator coolant hose crafted from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals. The hose features a molded design with two different inside diameters: 1.5 inches (38 mm) on one end and 1.75 inches (44 mm) on the other, accommodating specific radiator and engine connections. With a centerline length of 47.2 inches (1199 mm), this hose fits the cooling system layout of Dodge Ram 1500, 1500 Classic, 2500, and 3500 models. The absence of an internal spring allows for unobstructed coolant flow, reducing the risk of blockages or pressure drops.

Common Applications and Issues Addressed

  • Replacement of worn or cracked radiator coolant hoses in Dodge Ram trucks
  • Resolving coolant leaks caused by hose degradation or improper fit
  • Preventing overheating due to compromised coolant flow
  • Maintaining proper engine temperature regulation in Dodge Ram 1500 and 2500 series
  • Upgrading to a molded hose for improved durability and fitment

Installation Notes and Tips

  • Ensure the engine is cool before removing the old coolant hose
  • Check all hose connections and clamps for wear and replace if necessary
  • Verify the correct orientation of the molded hose before installation
  • Use proper coolant fluid compatible with EPDM hoses
  • Inspect the cooling system for leaks after installation and during initial operation

While specific warranty details may vary, Gates products generally come with a limited warranty against defects in material and workmanship, ensuring reliability for Dodge Ram 1500, 1500 Classic, 2500, and 3500 owners.
