First Time Start Preparations First Time Start Preparations System Checks Perform the following system checks before starting. Checking the Cooling System Check the cooling system as follows: 1. Make sure all drain cocks in the cooling system are installed (drain cocks are often removed for shipping) and are closed tightly. 2. Fill the coolant overflow surge tank with Detroit™ Genuine Coolant until coolant level stays between the low and full coolant marks on the tank. 3. Entrapped air must be purged after filling the cooling system. To do this, allow the engine to warm up with the pressure cap removed.
With the transmission in neutral, increase engine speed to 1000 rpm and add coolant to the surge tank as required. 4. Check to make sure the front of the radiator and charge air cooler (if equipped) are unblocked and free of debris. Checking and Monitoring the Oil Level Check the oil level as follows: WARNING: PERSONAL INJURY To avoid injury from slipping and falling, immediately clean up any spilled liquids. NOTICE: Do not add oil if the oil reading is in the crosshatch area on the dipstick. There are approximately 4.0 L (4.2 qt) from the fill mark to the full mark. Overfilling the oil pan can cause engine damage. NOTE:
If the engine operating temperature is below 60°C (140°F), the engine must be on a level surface and then shut down for 60 minutes for an accurate oil level reading. Otherwise, the engine must be brought up to an operating temperature of 60°C (140°F), parked on a level surface and then shut down for 20 minutes for an accurate oil level reading. 1. Check the oil level daily with the engine stopped and on a level surface. If the engine has just been stopped and is warm, wait approximately 20 minutes to allow the oil to drain back into the oil pan before checking. 26 All information subject to change without notice.
