Compatibility Notes:
- 2001–2002 trucks use dipstick 3937748 and may require tube 3937749 (newer tube design). If replacing a broken handle only, some owners transfer the handle to the original stick; otherwise swap to the updated tube.
- For common-rail (2003+) applications, use the CR-specific components—this 3935648 dipstick is not intended for 2003+ trucks.
