Routine Preventive Maintenance

This section describes the items listed in the maintenance interval tables. The Daily

instructions apply to routine or daily starting of the engine. They do not apply to a

new engine or one that has been operated for a considerable period of time.

Perform the following maintenance on the lubricating oil:

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.

NOTE: the dipstick has a positive locking device such as a lever or twist-

lock design that must be disengaged before pulling the dipstick out of the

guide tube. Use a shop rag to wipe off the end of the dipstick. Wait 15

seconds to allow any crankcase pressure to dissipate through the guide

tube and let the oil level settle in the oil pan.

2. Add the proper grade of oil to maintain the correct level on the dipstick.

Remove the dipstick from the guide tube. Before adding lubricating oil, refer

to "How to Select Lubricating Oil."

NOTICE: Do NOT fill beyond the maximum fill level on the dipstick, since

overfilling may result in high oil consumption and possible severe 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 five minutes for an accurate oil level reading.

3. Reinstall the dipstick and make sure it is fully inserted into the guide tube.

Remove the dipstick and read the oil level dipstick.

NOTICE: Do not add oil if the oil reading is in the crosshatch area on the

dipstick. There are approximately 5.0 L (5.2 qts) from the minimum mark to

the maximum mark on the dipstick. Overfilling the oil pan can cause engine

damage.

NOTICE: If the oil level is constantly above normal and excess oil has not

been added to the crankcase, consult with an authorized Detroit service

outlet for the cause. Fuel or coolant dilution of lubricating oil can result in

serious engine damage.
