1. Start the engine and warm it up to operating temperature.
2. Remove cover 4 (see fig. Radiator of the cooling system) expansion tank 9.
Attention! On a warm engine, the system is under pressure, so cover the plug with a rag and remove it with your hand outstretched.
3. Install the tester 2, which is a manual piston pump with a pressure gauge, on the neck of the expansion tank 1.
4. Increase the pressure in the cooling system to 0.1 MPa with the tester pump 2 and wait 10 minutes.
5. If the excess pressure in the system decreases within the specified time, then the system is leaking. Locate coolant leaks and repair leaks.
