a. Raise and secure hood (para. 3-8).
CAUTION
Do not permit dirt, dust, or grit to enter engine oil dipstick tube.
Internal engine damage will result if engine oil becomes
contaminated.
NOTE
Engine oil level is checked with engine off.
If oil level checks above 'FULL," it may be due to oil cooler drain
back. Operate the engine for one minute, shut down, wait one
minute, and recheck oil level.
Vehicles equipped with deep fording kit will have a sealed
dipstick.
b. Pull out dipstick (1) and check for proper oil level. Level should be at
crosshatch marks (2) between “FULL" and “ADD 1 QT.”
CAUTION
Do not overfill engine crankcase. Damage to engine will result.

Install a non-vented filler cap only. An incorrect filler cap will not
seal properly, causing water to enter and damage engine.
