SERIES 55 OIL LEVEL DIPSTICK ASSEMBLY

An oil level dipstick is used to check the oil level in the oil pan. The oil level dipstick is located in a tube attached by a threaded adaptor to an opening in the oil pan. See Figure 25404 . ‪

Oil Level Dipstick Assembly Location

NOTICE:

Maintain the oil level between the full and low marks on the oil level dipstick. Never allow it to drop below the low mark. No advantage is gained by having the oil level above the full mark. Overfilling may cause the oil to be churned by the crankshaft throws, causing oil foaming and aeration. Operating below the low oil mark may expose the pickup tube, causing aeration, pressure loss, and engine damage. ‪

Check the oil level after the engine has been stopped for at least 20 minutes. This will permit the oil to drain back into the oil pan. ‪

Oil level dipsticks are normally marked for use with vehicles parked on a level surface. Improper oil readings can result when the oil is checked in a vehicle on the grade, or if insufficient time is allowed for oil to drain back into the pan. ‪
