ENGINE Engine Lubrication Inspection of the Engine Oil Level 1. Make sure that the vehicle frame rail is standing on a flat and level surface. Refer to the engine manufacturer's Engine Operation and Maintenance Manual supplied with your vehicle for information about draining and refilling engine oil, engine crank case capacity, engine oil type, and changing oil filters, etc. NOTE It takes approximately 15 minutes for all the oil to run into the sump when the engine is ‘warm.’ If the level is checked immediately after switching off the engine, the dipstick will show a low oil level. 2. Make sure that the vehicle is horizontal, both lengthwise and crosswise.
Check this carefully on a vehicle with air suspension. Note that the engine may be inclined up to 4° depending on the vehicle model and wheelbase. Hot engine oil can be dangerous. You could be burned. Let the en- gine oil cool down before changing it. Failure to comply may result in death, personal injury, equipment or property damage. WARNING! 3. Twist the dipstick handle to unlock it, then pull the dipstick out of the holder. 5 4. Wipe the dipstick clean with a lint-free cloth. 5. Place the dipstick back into the holder. 6. Pull the dipstick out again and check the oil level. The oil level should always be between the 2 marks on the dipstick. 5-102 Y53-6077-1B1 (03/17)
