Warming Up the Engine
Run the engine at part throttle for about five minutes to allow it to warm up before
applying a load.
Inspection During Idling
While the engine is idling, inspect the transmission and crankcase for fluid leaks.
On DD15 and DD16 engines, check the Axial Power Turbine (APT) for oil leaks.
Checking the Transmission
While the engine is idling, check the automatic transmission (if equipped) for
proper oil level and add oil as required.
Checking for Fluid Leaks
Check for fluid leaks as follows:
1. Look for coolant, fuel, or lubricating oil leaks.
2. If any leaks are found, shut down the engine immediately and have the leaks
repaired after the engine has cooled.
Checking the Crankcase
Check the crankcase as follows:
1. If the engine oil was replaced, stop the engine after normal operating
temperature has been reached. Allow the oil to drain back into the crankcase
for about 60 minutes, then check the oil level.
NOTICE: Do not add oil if the oil reading is in the crosshatch area. There
are approximately 5.0 L (5.2 qt) from the fill mark to the full mark. Overfilling
the oil pan can cause engine damage.
2. If necessary, add no more oil than 5.0 L (5.2 qt) at a time to bring the level
to the proper mark on the dipstick. Use only the heavy-duty oils
recommended in the "How to Replace the Lubricating Oil and Oil Filter"
section in this manual.
