Subaru 11109AA151 Pan Assembly Oil

Disconnect the cable from the negative terminal of the battery. Remove the air filter housing, intake ducts, and the resonator, noting that depending on the vehicle's year and model, the air filter housing may not need to be removed. For turbocharged models, remove the intercooler. Remove the engine support brace and the radiator support brackets. Raise the vehicle and support it securely on jack stands, then remove the front wheels and tires. Remove the engine splash shield, and for non-turbocharged models, remove the exhaust manifold, which is necessary for added clearance when raising the engine for oil pan access. Drain the engine oil and remove the oil filter, then remove the dipstick tube by locating the mounting bolt on the cylinder head, removing the bolt, and sliding the dipstick tube out of the lower housing on the oil pan. Connect an engine hoist to the engine, remove the nuts from the engine mounts at the frame, and raise the engine two inches with the hoist. Remove the bolts securing the oil pan to the engine, tapping on the pan with a soft-faced hammer to break the gasket seal, and lower the oil pan from the engine, using a thin putty knife if necessary to break the seal without damaging the aluminum block. If the oil pump pickup tube interferes with oil pan removal, remove the pickup tube bolts and take both the oil pan and pickup tube out of the vehicle. For installation, scrape out all traces of the old gasket from the engine block and oil pan, being careful not to damage the sealing surfaces. Clean the oil pan with solvent and dry it thoroughly, checking for distortion and straightening any warped areas. Install a new O-ring on the pickup tube and place it in the oil pan, then apply a thin coat of gasket sealant to the new oil pan gasket and position it carefully on the oil pan. Raise the oil pan into position, install the pickup tube without disturbing the gasket, and secure the oil pan to the engine block, tightening the bolts hand-tight and then to the specified torque, avoiding over-tightening to prevent oil leaks. Complete the installation by reversing the removal process, refilling with fresh oil, installing a new filter, starting the engine, and checking for oil leaks.

Before doing this task, you must first disconnect the negative terminal of a battery and remove the air filter housing, intake ducts and resonator. In certain instances, taking out the air filter housing is not required depending on car's model and year. The intercooler has to be removed in turbocharged models. After that, take off engine support brace, radiator support brackets followed by raising the vehicle securely with jack stands and removing front wheels and tires. Eliminate engine splash shield as well as on non-turbo models exhaust manifold for extra clearance when raising engine to get access to oil pan bolts. Prior to removal of the dipstick tube from the engine hoist connection and lifting it 2 inches up, drain engine oil then remove oil filter as well. Loose nuts from the frame at engine mounts before removing bolts securing oil pan to engine by tapping soft-faced hammer against the pan so as to break gasket seal while letting down oil pan from it. Be careful so that you do not apply force on an oil pan unless all screws are detached from it completely. Whenever discharging any oil pump pickup tube if this is interfering with its removal process, then you should detach them by extracting their related cap screws that secure them into place after which grab an entire assembly easily using your hands or fingers while pulling upwards away from lowermost part of a vehicle when necessary. Scrape any old traces of a gasket left over during installation off; clean surfaces of both O-ring of pickup tube and also those located inside an opened portion within a top flat surface area around edge where bolts go through together with groove; put new one onto that same position or area close enough until another begins just above upper edge adjacent towards openings beneath screws themselves respectively without squeezing too tightly after it has been placed rightly against hole opening entirely except establishing contact exactly there like other things had been done including inserting these fasteners into corresponding holes before finally tightening everything carefully since it is actually easier than otherwise. Apply some thin layer of gasket sealant onto brand new oil pan gasket now position carefully on top plate without making contact between both materials, raise oil pan into proper place then install pick tube followed by tightening its corresponding mounting screws loosely ensuring that none has been disturbed during these operations as well; make sure you don't tighten them too strongly either after they have been properly fitted. Bolt oil pan to engine block gradually starting from center towards ends with an avoidance of overtightening in order not to cause leakage of oil. Finally, complete installation process back up filling fresh fuel plus new filter, start car engine and also check for any signs indicating whether there is a leak or not.
