Open the ball valve located on the hoses according to the connection and vehicle type and start the engine.Let the engine run on idle andgive occasionallyshort bursts up to 2500 - 3000 rpm. The pressure fluctuations this causes will help to remove stubborn dirt.The cleaning process takes about min.30-45 minutes, depending on the level of contamination. Then assemble the vehicle to its original condition, check for leaks anddo a test drive of at least 10km (6 miles).
