PRODUCT FACTS

Find out more about ACDelco Professional Radiator Caps and how they fit into the Cooling System with the product facts below.

Function:

The radiator transfers heat from the engine’s coolant to the outside air while the radiator cap seals and pressurizes the cooling system.

Service and 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, 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.
