Detailed Product Description

The Gates Molded Coolant Hose 21965 is engineered to meet the specific cooling system requirements of Nissan Maxima vehicles. Its EPDM construction offers excellent resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity over time. The molded design ensures a precise fit with no need for additional modifications, reducing installation time and potential leaks. With an inside diameter of 1.34 inches (34 mm) on one end and 1.56 inches (40 mm) on the other, this hose accommodates the radiator connections accurately. The 24.2-inch (615 mm) centerline length provides the correct routing path within the engine bay. This hose does not contain an internal spring, which allows for unobstructed coolant flow and reduces the risk of hose collapse under vacuum conditions.

Applications and Common Issues Addressed

  • Replacement of worn or cracked radiator coolant hoses in Nissan Maxima models
  • Prevention of coolant leaks caused by hose degradation
  • Restoration of proper coolant flow to avoid engine overheating
  • Elimination of hose collapse or blockage due to internal spring absence
  • Ensuring secure and leak-free connections with molded hose design

Installation Notes and Tips

  • Verify compatibility with Nissan Maxima model year before installation
  • Inspect radiator connections for corrosion or damage prior to hose installation
  • Use appropriate clamps to secure hose ends firmly without over-tightening
  • Ensure coolant system is depressurized and cooled before removing old hose
  • Flush cooling system if necessary to remove debris before installing new hose
