4.7L POWER TECH V-8 349LEFTCYLINDERHEAD OILGALLERYFigure 6 - 7Engine OilAn SAE viscosity grade is used to specify the viscosity ofengine oil. Use only engine oils with multiple viscositysuch as SW-30 or 1OW-30. These are specified with a dualSAE viscosity grade which indicates the cold-to-hottemperature viscosity range. Select an engine oil that is bestsuited to your particular temperature range and variation(Figure 6-8). The 4.7L engine oil capacity (with filterchange) is S.7L (6.0 quarts).ENGINE OIL VISCOSITY GRADES"F -20'oc -290 -18" -120 -70 160 270 380IFigure 6 - 880b89880 IEngine Oil Level InspectionCaution: DO NOT overfill crankcase with engine oil;pressure loss or oil foaming can result.Inspect engine oil level approximately every 800lulometers (500 miles). Unless the engine has exhibited aloss of oil pressure, run the engine for about five minutesbefore checking oil level. Checking engine oil level on acold engine is not accurate.To ensure proper lubrication of an engine, engine oil mustbe maintained at an acceptable level. The acceptable levelsare indicated between the ADD and SAFE marks on theengine oil dipstick.1.2.Position vehicle on level surface.With engine OFF, allow approximately ten minutesfor oil to settle to bottom of crankcase, remove engineoil dipstick.3. Wipe dipstick clean.4.5.6.Install dipstick and verify it is seated in the tube.Remove dipstick, with handle held above the tip, takeoil level reading.Add oil only if level is below the ADD mark on dipstick.
