INCORRECT OIL LEVEL REPLACE DIPSTICK AND TUBE

NOTE: PER MIKE AT GM SPECIAL PARTS ASSISTANCE DIPSTICK P/N 14085794 HAS BEEN SUPERSEDED BY P/N 14092376. 4/18/86. SOME 1982-84 P3500 MOTOR HOME CHASSIS WITH THE 7.4L (454) ENGINE MAY INDICATE AN OVERFILL CONDITION ON THE DIPSTICK AFTER AN OIL CHANGE. THE OWNER'S MANUAL SPECIFIES THAT THE 7.4L (454) ENGINE HAS AN OIL CAPACITY OF SEVEN QUARTS. HOWEVER, AFTER THE OIL IS CHANGED, THE PROPER AMOUNT OF OIL ADDED, AND THE ENGINE MAY APPEAR TO BE OVERFILLED BY ONE QUART. DUE TO DIPSTICK LOCATION AND CONFIGURATION ON THIS MODEL VEHICLE, THE DIPSTICK TUBE IS EXTREMELY DIFFICULT TO MEASURE AND CONFIRM THAT IT IS CORRECT; THEREFORE, TO DETERMINE THE ACCURACY OF THE DIPSTICK, RUN THE ENGINE UNTIL IT REACHES NORMAL OPERATING TEMPERATURE. SHUT OFF ENGINE AND LET VEHICLE SET FOR 10-15 MINUTES. THE VEHICLE MUST BE ON A LEVEL SURFACE. REMOVE THE OIL PAN DRAIN AND LET OIL DRAIN FOR 7-10 MINUTES. REPLACE THE OIL FILTER. DO NOT PREFILL THE NEW OIL FILTER. REINSTALL THE DRAIN PLUG AND ADD SEVEN QUARTS OF OIL TO THE ENGINE. RESTART THE ENGINE AND LET VEHICLE STAND 10-15 MINUTES. REMOVE DIPSTICK AND CHECK OIL LEVEL. IF THE OIL LEVEL IS 1/4" - 3/8" OVER THE FULL MARK ON THE DIPSTICK, THEN A NEW DIPSTICK, P/N 14085794. AND DISPSTICK TUBE ASSEMBLY, P/N 14085796, SHOULD BE INSTALLED. AN "O" RING SEAL, P/N 274244, MUST ALSO BE USED WHEN REPLACING THE TUBE ASSEMBLY (SEE ILLUSTRATION #1).

Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
