1. Screw adapter MS 554-01 instead of the cap onto the neck of the expansion tank (see illustration).

2. Warm up the engine to operating temperature. The bottom radiator hose should be hot.
3. Stop the engine.
4. Connect the MS 554-05 pressure device to the adapter MS 554-01 (see illustration 3.1).
5. Use the instrument's hand pump to pressurize the system. This pressure should be approximately 0.1 bar below the pressure at which the outlet valve on the expansion tank filler cap opens. The pressure can be set on the pressure gauge on the device. The opening pressure of the exhaust valve is indicated on the cap:
- vehicles with a 1.6 liter petrol engine (K7M) /2.6 liters. Valve opening pressure (of blue color) 1.6 bar;
- vehicles with a 1.6 liter petrol engine (K4M) /1.4 liter, 1.9 liter diesel engine. Valve opening pressure (Brown) 1.2 bar.
The pressure created in the system must be maintained for at least 2 minutes. If pressure during drops, then establish places of leak in the cooling system. Leaks can be identified by escaping coolant.
6. Slowly unscrew adapter MS 554-01 on MS 554-05 to relieve pressure. When unscrewing, place a rag on the adapter.
Attention! Risk of burns from hot liquid.
7. Check up the final valve which is in a cover of a broad tank. It is designed to relieve excess pressure from the cooling system. The opening pressure of the exhaust valve is indicated on the cap:
- vehicles with a 1.6 liter petrol engine (K7M) /2.0 liters. Valve opening pressure (of blue color) 1.6 bar;
- vehicles with a 1.6 liter petrol engine (K4M) /1.4 liter, 1.9 liter diesel engine. Valve opening pressure (Brown) 1.2 bar.
8. Screw the MS 554-06 adapter onto the MS 554-05 instrument to test the valve, and then fix the expansion tank neck cap on the instrument (see illustration).
3.8 Screw the MS 554-06 adapter onto the MS 554-05 device to test the valve, and then fix the expansion tank neck cap on the device
9. Use the instrument's hand pump to pressurize the system. This pressure must stabilize within the valve opening pressure of±0.1 bar. Otherwise, replace the cover.
10. Screw the cap onto the filler neck, after checking the condition of the rubber seal, which should be replaced if damaged.
Attention! Be sure to replace the expansion tank cap if fluid has leaked from the outlet valve.
