First: Run the motor until the temperature of the water is at maximum heat and all working parts of the motor have been brought to their normal operating temperature.

Second: After placing the car in position where it will remains drain the water and again run the motor for several minutes in order to thoroughly, dry out the water passages.

Third: Remove each spark plus and place approximately a tablespoon full of light machine oil on the top of each piston.

Fourth: Turn the motor over two (2) complete revolutions by hand.
