Product Description
Keep your first-gen 5.9L Cummins alive and accurate with a genuine CUMMINS 3916850 OEM ENGINE OIL DIPSTICK. This OE dipstick is calibrated for the 1989–1993 5.9L 12-valve (VE-pump) Dodge Ram, so your oil level readings match factory spec – not somebody’s “close enough” aftermarket copy.
If you’re battling oil consumption, leaks, or a questionable service history, starting with the correct dipstick and tube combo is critical. The 3916850 dipstick drops into the matching Cummins oil gauge tube and uses OE markings to show SAFE / FULL levels the way Cummins intended, helping prevent overfilling, foamed oil, and low-level bearing damage.

FAQ
WILL THIS FIT MY 1989–1993 5.9L CUMMINS RAM?Yes – Cummins 3916850 is the OE engine oil dipstick used on many BS2 5.9L B-Series applications, including most 1989–1993 Dodge Ram 5.9L 12-valve trucks. Always confirm by VIN/engine serial number and by matching your existing dipstick/tube before ordering.
DO I NEED THE MATCHING CUMMINS DIPSTICK TUBE?
For accurate readings, the dipstick and tube must be a matched pair. Many first-gen 5.9L applications use Cummins oil gauge tube 3905799 with this 3916850 dipstick, but you should verify by VIN/ESN or by part number stamped on your existing tube.
WHAT ABOUT LATER 5.9L AND 6.7L CUMMINS TRUCKS?
1994–1998 12-valve, 1998.5–2002 VP44, and 2003–2007 common-rail 5.9L trucks use different dipsticks and tubes, as do 6.7L applications. For example, 2003–2007 5.9L trucks use a different OE dipstick such as Cummins 3959009 , while 6.7L trucks use cable-style dipsticks like Cummins 4938970 .
IS THIS A GENUINE CUMMINS PART OR AFTERMARKET?
This listing is for a genuine Cummins 3916850 dipstick, not an aftermarket copy. You get OE-correct markings, materials, and handle indexing for reliable oil-level checks and long-term durability.
HOW SHOULD I CHECK OIL LEVEL WITH THIS DIPSTICK?
Bring the engine to operating temperature, park on level ground, shut the engine off, and wait a few minutes for the oil to drain back to the pan. Pull the dipstick, wipe it clean, reinsert fully until it seats on the stop, then remove and read the oil level. Adjust oil quantity to bring the level to the FULL mark without overfilling.
