WARNING: If the radiator cap is removed when the engine and radiator are still hot, extremely hot fluid and steam may spew out under pressure. This can cause severe burns. Wait until the engine coolant temperature has lowered before removing the radiator cap.
  1. Check cooling system for leakage or damage.
  2. Remove radiator cap, see RADIATOR CAP REMOVAL AND INSTALLATION .
  3. Check coolant for proper level and freeze protection.
  4. Check coolant leaks from cooling system according to the following procedure.
    1. Attach pressure tester (1) to water filler as shown in figure, and then apply specified pressure to cooling system.
