Engine Oil Check
This engine has a wet-sump design, meaning the engine oil is contained in the bottom of the crankcase.
To check the oil level, follow the procedure listed below:
1. Ensure the engine is cold and safe to touch.
2. Make sure that the vehicle is on a level surface and that the transmission in PARK.
3. Locate the dipstick (1) on the right side of the unit, shown below.
4. Remove the dipstick and wipe it dry with a clean cloth.
5. Reinstall the dipstick and push it into place. Make certain the dipstick is inserted all the way into the dipstick tube to keep the depth of the dipstick consistent.
6. Remove the dipstick and check the oil level.
7. Add the recommended oil as necessary to bring the oil level within the SAFE range on the dipstick, shown below. Do not overfill. The recommended fluid is 5W-40 Synthetic Diesel Oil (part number 2879832).
Note that a rising oil level between checks during cold weather operation can indicate contaminants such as gas or moisture collecting in the crankcase. If the oil level is over the upper mark, change the oil immediately.
8. With the cargo box raised, add engine oil through the oil fill cap (2) located on top of the valve cover, under the cargo box.
9. When finished, reinstall dipstick. Lower the cargo box and secure in position.
10. Check around and under the engine for oil leaks.
