90pontiac05 Bulletin Number: 89-6-47A Reference Number: 906104R Publish Date: 3/90 Subject: PROPER INSTALLATION OF 75 MM OIL FILTER Models Affected: 1980-89 ALL MODELS WITH 75 MM FILTERS This bulletin cancels and replaces bulletin 89-6-47 issued 5/89. This bulletin is being revised to update Oil Filter Installation Instructions. To prevent leakage of small 75 mm oil filters such as PF-40, PF-45, PF-47, PF-51, etc., it is very important that the installation instructions listed below are closely followed. Remove old filter by turning counter clockwise. Clean gasket sealing area on Engine Oil Filter Mounting Surface. (If engine has an adapter base, make sure threaded nipple or bolt is properly torqued.) Lightly oil gasket with clean oil and install filter. After the oil filter gasket contacts the oil filter adapter base, tighten 3/4 to 1 full turn. When necessary, use a cap-type wrench, AC Delco OF17W or equivalent, or strap type wrench with swivel handle to insure proper installation. 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.
