1. Loosen radiator cap slowly to release pressure and remove filler cap.
If the engine is to be stored in, or shipped to, an area with below freezing temperatures, the cooling system must either be protected to the lowest expected ambient temperature, or drained completely.Never add coolant to an overheated engine, allow engine to cool first.Do not use Caterpillar cooling system conditioner with Dowtherm 209.
2. Remove radiator drain plug.3. Remove engine block drain plugs.
Use all cleaning solutions with care.
