Usage:
 |
At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Drain the coolant only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap from the radiator slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to avoid personal injury. |

Always wear goggles when working on air conditioning systems. The system is under pressure at all times, engine running or not. Escaping Freon-12 (C C12 F2 Dichloro Difluoro Methane) can cause freezing of human flesh. Do not smoke while working on air conditioning. Inhaling Freon-12 through any smoking material, although not toxic or flammable, can cause violent illness. Also heat must never be applied to a charged system. See Air Conditioning And Heating Service Manual Form No. SENR3334-01, for more information on removal and installation of lines and refrigerant from the system. |
