Did You Know?

The best way to check a coolant hose for degradation is to squeeze the hose near the clamps or connectors using the following procedures:

  • Always make sure the engine is cool before inspecting the cooling system.
  • Use your fingers and thumb (not the whole hand) to check for hose weakness.
  • Squeeze near the clamps or connectors, as most hose failures occur in this area.
  • Check for any noticeable difference in feel between the middle and ends of the hose.
  • If the ends feel soft or mushy, replacement is recommended.


What It Does:

The cooling system removes heat from the engine to keep it running at the proper temperature. In the cooling system, belts drive the water pump, circulating coolant throughout the system.

Service & Maintenance:

  • Maintain proper coolant levels and check level monthly. (Note: Never attempt to remove a radiator cap while the engine is hot. Serious injury could result.)
  • Replace coolant with a mixture of antifreeze and water according to the vehicle manufacturer’s recommendations.
  • Inspect engine belts for cracks or missing sections; check belt tension.
  • Evaluate radiator and radiator cap for leaks, corrosion or worn cap gasket.
  • Examine hoses every 12 months. Look for leaks, cracks or rot. Replace when showing signs of wear.
  • Tighten any loose clamps. Replace clamps when replacing hoses.
  • Have cooling system inspected immediately if instrument panel-mounted temperature gauge indicates engine overheating.
  • Periodically, remove bugs, leaves and other debris from the front of the radiator. They can block airflow and substantially reduce cooling efficiency.
