Details on the Molded Coolant Hose Product Line

The Gates Molded Coolant Hose line focuses on delivering hoses that are pre-formed to exact OEM specifications. This eliminates the need for bending or shaping during installation, reducing the risk of kinks or leaks. The molded construction of part number 23140 ensures a secure fit and reliable coolant transfer in the specified GM vehicles.

Technical Description and Specifications

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals. Both ends of the hose have an inside diameter of 1.27 inches (32 mm), matching OEM dimensions for a proper seal. The centerline length of 32.3 inches (820 mm) allows for precise installation without stretching or compression. The hose does not contain an internal spring, which supports consistent coolant flow without obstruction. It is a molded hose, not modular, and does not include quick connect fittings or branches.

Applications and Common Issues Addressed

  • Replacement of worn or cracked radiator coolant hoses in Buick Montana, Chevrolet Uplander, Pontiac Relay, and Saturn Terraza
  • Prevention of coolant leaks caused by hose deterioration or improper fit
  • Restoration of proper coolant flow to avoid engine overheating
  • Elimination of hose kinks or deformation due to molded design
  • Maintenance of cooling system integrity for reliable vehicle operation

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to prevent burns. Verify that the hose ends and clamps are clean and free of debris before installation. The molded design of the Gates 23140 hose allows for straightforward alignment with factory coolant ports. Use appropriate clamps to secure the hose ends without over-tightening, which can damage the hose. Inspect the cooling system for leaks after installation and during initial operation.

Gates Molded Coolant Hose 23140 is manufactured to meet or exceed OEM standards for durability and performance.
