2. Connect the tester to the opening of the expansion tank or radiator
3. Start the engine (preferably already warm), bring to the increased turnover in order to achieve greater combustion pressure.
4. Leave the engine on slightly elevated speeds and observe the behavior of reaction fluid
5. If the fluid turns YELLOW or GREEN , a combustion leak is present. Change the color of the liquid reaction to yellow(petrol engines, LPG) or green (diesel)
