SPECIFICATION

GENERAL SPECIFICATION

Recommended oil: API standard SM with the "Energy Conserving" logo is printed.

ILSAC standard, GF4 "Star burst mark" label is on the container.

SAE Viscosity Chart. Scheme 53

The proper viscosity helps vehicle get good cold and hot starting by reducing viscous friction and thus increasing cranking speed.

Note. If the vehicle is used in areas with very high temperatures or for other heavy duty applications, the following viscosity oils may be used: API standard: SM or SL SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50.

Exploded View Of Engine Oil Component. Scheme 54

CAUTION

1. Wear work clothing, including a cap, protective goggles, and protective shoes during operation.
2. Remove contamination including dirt and corrosion before removal, installation or disassembly.
3. Keep the disassembled parts in order and protect them from dust and dirt.
4. Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly, and replacement.
5. Be careful not to burn yourself, because each part in the vehicle is hot after running.
6. Be sure to tighten fasteners including bolts and nuts to the specified torque.
7. Place shop jacks or rigid racks at the specified points.
8. Before disconnecting electrical connectors of sensors or units, be sure to disconnect the ground cable from battery.

INSPECTION

INSPECTION CHART

Scheme 59

1. Park the vehicle on a level surface.
2. After turning off the engine, wait a few minutes for oil to drain back into the oil pan before checking the level.
3. Just after driving or while the engine is warm, engine oil level may show in the range between the "F" line and notch mark. This is caused by thermal expansion of engine oil.
4. Remove the oil level gauge and wipe it clean.
5. Reinsert the level gauge all the way. Be sure that the level gauge is correctly inserted and in proper orientation.
6. Remove it again and note the reading. If the engine oil level is below the "L" line, add oil to bring the level up to "F" line. NOTE: To prevent overfilling the engine oil, do not add oil above "F" line when the engine is cold. (Scheme 56): Identifying Oil Level Gauge

Scheme 60

Scheme 61

Scheme 62

1. Open the engine oil filler cap for quick draining of engine oil.
2. Drain the engine oil by loosening the engine oil drain plug. (Scheme 57): Identifying Oil Drain Plug

5. Install the service hole cover.
6. Use the engine oil of proper quality and viscosity, fill engine oil through the oil filler duct up to upper level on level gauge. Make sure that the vehicle is placed level when checking oil level. Recommended oil: API standard SM with the "Energy Conserving" logo is printed. ILSAC standard, GF4 "Star burst mark" label is on the container. Engine oil capacity: Upper level 4.0 l (4.2 US qt, 3.5 Imp qt) Lower level 3.0 l (3.2 US qt, 2.6 Imp qt) (Scheme 59): Identifying Oil Drain Plug The proper viscosity helps vehicle get good cold and hot starting by reducing viscous friction and thus increasing cranking speed. CAUTION: When replenishing oil, it does not matter if the oil to be added is a different brand from that in the engine; however, use oil having the API standard and SAE viscosity No. designated by SUBARU. NOTE: If the vehicle is used in areas with very high temperatures or for other heavy duty applications, the following viscosity oils may be used: API standard: SM or SL SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50.
7. Close the engine oil filler cap.
8. Start the engine and warm it up for a time.
9. After the engine stops, recheck the oil level. If necessary, add engine oil up to the upper level on level gauge. (Scheme 60): Identifying Engine Oil Level Gauge

1. After installing the oil filter, run the engine and make sure that no oil is leaking around seal rubber. NOTE: The filter element and filter case are permanently jointed; therefore, interior cleaning is not necessary.
2. Check the engine oil level. < Ref. to «INSPECTION»(/subaru/impreza-wrx/gdgg-2-2005-2007/remont/lubrication-system/#lubrication-h4dotc) , Engine Oil. >
