New Dipsticks With Full Range Readings
The 3176 uses a dipstick that has a FULL RANGE zone versus other dipsticks that have the traditional FULL mark. This dipstick is used to account for variations in engine installations. Engine oil level will vary depending on angle and slant of OEM engine installation (angle = front to back tilt, slant = sideways tilt).To determine the correct "FULL" mark in the FULL RANGE zone and prevent overfilling or underfilling the crankcase, it is important to calibrate the dipstick. The following procedure can be used:Calibration
Use the following procedure to calibrate "FULL RANGE" dipsticks. The dipstick should be calibrated when the truck is delivered to the customer. However, a convenient time to calibrate the dipstick is at the first oil change.Refer to the PM Level 1 of the "Maintenance Management Schedule" of this publication for the proper oil change interval.To verify the "ADD" mark and establish the actual "FULL" mark in the FULL RANGE zone, use the following procedure: Truck must be parked on a level surface.1. Operate the engine until it reaches normal operating temperature.2. Stop the engine. Drain the oil and change the oil filter.3. Fill the crankcase with 22 U.S. qts (21 L) of oil. DO NOT start the engine.4. Allow the oil to drain back to the sump for a minimum of 10 minutes.5. Remove the dipstick. The oil level should be at the "ADD" mark. If it is not, mark the actual level on the dipstick. This is now the correct "ADD" mark.6. Add an additional 3.5 U.S. qts (3.3 L) of oil to the sump. Allow enough time for the oil to drain into the sump. Again, check the level on the dipstick and DO NOT start the engine.7. This is the correct "FULL" mark on the FULL RANGE dipstick. Mark the new "FULL" mark level on the dipstick. Remote mounted or auxiliary filters require additional oil. Add the amount of oil required to fill the additional system capacity if it is known.Refer to Refill Capacity chart in this publication for information. If the additional capacity is not known, proceed with step number 8.8. Start the engine and operate until it reaches normal operating temperature. Stop the engine.9. Remove the dipstick. Add enough oil to bring the oil level to the "FULL" mark in the FULL RANGE zone. This is the additional amount needed to fill the oil filter(s) and bypass filter, if equipped.The oil level should be at the new calibrated "FULL" mark. If it is not, add oil until the oil level reaches the "FULL" mark.Any "FULL RANGE" dipstick for the 3176 Truck engine can be calibrated using this procedure.
