Detailed Product Description

The Gates Molded Coolant Hose 20594 is engineered to meet the cooling system requirements of Dodge Charger and Dodge Dart models. Its molded construction eliminates the need for multiple hose segments, reducing potential leak points and improving reliability. The hose features a consistent inside diameter of 1.5 inches (38 mm) on both ends, ensuring proper coolant flow and system pressure. With a centerline length of 16.5 inches (419 mm), it fits precisely within the engine bay, maintaining optimal routing and clearance.

Manufactured from EPDM (ethylene propylene diene monomer) rubber, this hose offers excellent resistance to heat, ozone, and coolant chemicals, which helps extend service life. The absence of internal springs or quick connect fittings simplifies the design and installation process.

About the Molded Coolant Hose Product Line

The Gates Molded Coolant Hose line focuses on delivering pre-formed hoses that match OE specifications for fit and function. These hoses are molded to exact dimensions to ensure proper fitment and reduce installation time. The Molded Coolant Hose series is designed to withstand the thermal and chemical demands of modern cooling systems, making them suitable replacements for factory-installed hoses in compatible vehicles.

Common Applications and Problem Solving

  • Replacement of worn or cracked radiator coolant hoses in Dodge Charger and Dart
  • Resolving coolant leaks caused by hose degradation or swelling
  • Addressing overheating issues related to restricted or collapsed hoses
  • Maintaining proper coolant flow and pressure within the cooling system
  • Preventing coolant contamination from hose material breakdown

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to avoid burns. Verify the hose routing matches the original to prevent kinks or interference with other engine components. Use appropriate clamps to secure the hose ends firmly but avoid overtightening, which can damage the hose. Inspect adjacent components for wear or damage during installation.
