pump and the external air cooler before checking the motor direction on an air-cooled system.
WARNING
Do not attempt to repair a leak with pressure in the system.
WARNING
Use a piece of cardboard or other solid material to check for leaks when the pump is on. Do not
use hands, cloth, paper, or towels.
