1) Run the engine for 5 minutes and then stop it.

2) Drain the water of radiator.

3) Pour MARPA Cooling System Flush into the radiator; fill the rest with clean water.

4) Run the engine for 20 minutes. If the radiator was not washed for a long time, double this time.

5) Switch off the car engine; and drain the water out of the water tank.

6) Fill the radiator again with clean water and allow the engine to run for another 5 minutes. Then, drain the water again.

7) Fill the car radiator with clean water again.

8) One bottle of MARPA Cooling System Flush treats less than 10 liter water tanks; apply two bottles for bigger cooling systems.

9) The cleaning time can be extended to 24 hours if the water tank has not been cleaned for a long time. In such cases, it would be better to add a bottle of MARPA Radiator Rust Preventive (M800) into the cleaned water tank either.
