Execution order
1. Wait until the radiator cools down to 38°C, remove the radiator cap and connect a cooling system leak tester instead.
2. Create a pressure of 139.3 kPa in the cooling system.
3. Make sure that the pressure of 139.3 kPa in the cooling system is maintained for 2 minutes.
Warning: Do not remove the radiator cap when the engine is hot, as escaping vapors can cause severe burns.
Warning: Cover the radiator cap with a thick rag and slowly unscrew the cap until you hear the hissing sound of escaping steam.
Warning: After the steam stops escaping, slowly unscrew and remove the radiator cap.
4. Otherwise, locate the leak and repair it.
