GOODWRENCH SERVICE REPLACEMENT ENGINES Section V Page 60 August 2004 12351924 151 CID Reman 2.5L 1989 Chevrolet, Pontiac, A (LR8)(2.5R) Oldsmobile, Buick Engine-Specific Content: Front Cover and Oil Pan INSTALLATION INSTRUCTIONS The Goodwrench 2.5 engine has been remanufactured subsequent to the model year of the vehicle and may incorporate design refinements not included in original service information (i.e., 1982 engines may incorporate design features normally associated with 1987 models). If future service is required for this engine, consult GM Parts catalogs, GM Parts and Accessories information bulletins and dealer service bulletins for proper service parts and service procedures necessary to accommodate these revisions. Before installing this engine, refer to the appropriate vehicle service chassis manual for proper repair procedures and owner's manual for capacities. Initially add 3 quarts of Starburst certified oil in viscosity suitable to your climate conditions. Prime system and check oil level on dipstick. Add oil as required to reach full mark. Use new seals and gaskets. Transfer all necessary components to the replacement engine. Thoroughly clean all old parts to avoid possible contamination and leaks. If harmonic damper hub is grooved in seal contact area, replace the damper to prevent oil leaks. The rear most intake manifold bolt MUST go through the engine lift bracket or an equivalent thickness spacer. Failure to do so permits the bolt to contact the #8 push rod resulting in lifter noise and possible damage to the engine. Rocker cover installation: A) use RTV on dimpled covers, B) use cork/rubber gasket (with compression limiters) with non-hemmed holes on covers, C) use silicone/steel reinforced gasket with non-dimpled, non-hemmed rocker covers. Attach the enclosed decal to clean rocker cover. Install the appropriate bushing in the crank end depending on if equipped with automatic or manual transmission. Check the cooling system for proper operation. CAUTION: The oil pump in this engine must be primed before starting engine. Turn engine for a minimum of 30 seconds with the coil or injector wire disconnected. Oil pressure warning light must go off (if equipped with a pressure gage, the gage must read 30 PSI minimum). DAMAGE WILL RESULT IF ENGINE IS STARTED WITHOUT OIL OR IF OIL PUMP IS NOT PRIMED.
