OIL FILTER LEAKAGE PROPER INSTALLATION PROCEDURE

SUBJECT: PROPER INSTALLATION OF 75mm OIL FILTER

VEHICLES AFFECTED: ALL YEARS AND ALL MODELS

To prevent leakage of small 75mm oil filters such as PF-40, PF-45, PF-47, PF-51, etc., it is very important that the installation instructions on the label are closely followed.

Lightly oil gasket with clean oil and install filter. After the oil filter gasket contacts the oil filter adapter base, tighten 2/3 turn minimum. When necessary, use a cap-type wrench such as Kent-Moore J-29142 or equivalent.

With engine oil at proper level, run engine three minutes and thoroughly check filter area for leaks.

IMPORTANT: Be certain to follow replacement oil filter usage applications.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. 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. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
