Check the coolant in the radiator using the coolant level sight gauge, or observe the coolant level through the opening in the end of the hood. ENGINE START-UP If it is necessary to remove the radiator cap, shut the engine off, allow the engine to cool, and slowly remove the radiator cap. DO NOT remove the radiator cap when the cooling system is pressur- ized . Never attempt to start the engine by shorting across the starter terminals. This may cause fire, or serious injury or death to anyone in the machine’s path. Start the engine from the operator’s seat only.
If the truck is equipped with an auxiliary cold weather heater system, do not attempt to start the engine while the heaters are in operation. Damage to the coolant heaters will result! If the engine is hot, allow the coolant to cool before removing the fill cap or draining the radia- tor. Serious burns may result if the coolant is not allowed to cool. 31.
