OM2201 Warnings and Cautions - Section 22 Page 22-3 A plate is mounted on the left hand side of the trans- mission oil pan to provide instructions for proper transmission oil level check. Warning plates are mounted on the truck frame in front of and to the rear of both front tires to alert all persons to stay clear when the truck is being steered. A warning plate is mounted on top of the radiator surge tank cover near the radiator cap.The engine cooling system is pressurized. Always turn the key switch off and allow the engine to cool before remov- ing radiator cap.
Unless the pressure is first released, removing the radiator cap after the engine has been running for a time will result in the hot coolant being expelled from the radiator. Serious scalding and burning can result. Use caution when servicing radiator. The system is pressurized because of thermal expansion of coolant. DO NOT remove the radiator cap while the engine is hot. Severe burns may result.
