Personal injury can result from hot coolant, steam and alkali. At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns. Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand. Cooling System Conditioner contains alkali. Avoid contact with skin and eyes. |
 |
Note: Put identification of all lines, hoses, wires, and tubes for installation purposes. Install a cap or a plug in all lines, hoses, or tubes that are disconnected in order to prevent fluid loss. The caps or plugs will also prevent foreign material from entering the system.
