Engine Cooling System Inspection

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.

Check cooling system for leakage or damage.
Remove radiator cap.
Check coolant for proper level and freeze protection.
Check for check cooling system for leakage from cooling system using the following procedures:
1. Attach special tool to water filler, and then apply specified pressure to cooling system.

2. Check that cooling system holds the pressure.
  If cooling system does not hold applied pressure, check cooling system for leakage.
Check radiator cap according to the following procedure.
1. Attach special tool to radiator cap (1), and then apply specified pressure.
  NOTE: Apply water or coolant to rubber seals before attaching special tool to radiator cap.
