Note: To avoid burns from hot coolant, release excess pressure slowly when testing the cooling system.
Attention! Wipe dry all areas to be tested.
Caution: When disconnecting the air tester, be careful not to spill coolant.
Attention! When removing and installing the pneumatic tester, as well as during pressure testing, do not damage the radiator filler pipe.

Check the coolant level. It should be at the level of the radiator filler neck. Install a pneumatic tester and create excess pressure of 160 kPa. Check for fluid leaks from the radiator hoses and joints.
If leaks are present, repair or replace the relevant components.
