2. Make sure the coolant level reaches the lower edge of the filler neck.
3. Attach the radiator cap tester to the filler neck and pressurize the cooling system to 140 kPa. Make sure that the pressure in the cooling system is maintained for 2 minutes.
Attention!
- 1. Do not remove the radiator cap when the engine is hot, as the escaping steam can cause severe burns. Cover the radiator cap with a thick rag and slowly unscrew the cap until the escaping steam hisses. After the steam stops escaping, slowly unscrew and remove the cap from the radiator.
- 2. Wipe dry the system components and connections being checked.
- 3. When the tester is removed, be careful not to spill coolant from the tester.
- 4. Be careful when installing and moving the device and when checking, do not damage the radiator filler neck.
- 5. Otherwise, locate the leak and repair it.
