Note. To avoid burns from hot coolant, slowly release excess pressure while pressurizing the cooling system.
Attention! Wipe dry all places of the intended test.
Attention! When disconnecting the pneumatic tester, be careful not to spill any coolant.
Attention! When removing and installing the pneumatic tester, as well as during pressure testing, do not damage the radiator filler pipe.
Check coolant level. It should be at the level of the radiator filler neck. Install a pneumatic tester and apply an overpressure of 160 kPa. Check for fluid leaks from radiator hoses and connections.
If there are leaks, repair or replace the relevant components.
