Q: What are the necessary tools and steps for spark plug replacement on Subaru Outback?
A: In mainly cases, the tools required for change of spark plugs include a special ratchet socket, various extensions and gap gauge to check and adjust gaps on new plugs. . Use a torque wrench to tighten down the new plugs. The best way to replace spark plugs is through pre-purchasing new ones, adjusting them to correct gap and removing one plug at a time. For your specific engine, make sure you choose the correct type of plug when purchasing replacement spark plugs from an auto parts store. Wait until all heat has dissipated from the engine before turning off any plug that exists in it. These engines have aluminum cylinder heads which can be ruined if you take out these spark plugs while the engine is still hot. While waiting for the motor to become cold, inspect new plugs for defects and set their gaps correctly. The clearance is determined by inserting a feeler gauge of appropriate thickness between electrodes at the tip of the plug. The distance between electrodes must match that indicated on Emissions Control Information label. If this spacing is incorrect, use adjuster on gauge body to slightly bend side electrode towards curved side until desired clearance is achieved; or if side electrode does not correspond with center electrode exactly-change its position using adjuster of such kind as well Check for cracks in porcelain insulator On turbocharged engines remove battery and secondary air pump On non-turbocharged engines remove single wire attached to one spark plug Blow out with compressed air if available any dirt or other foreign material around spark plug hole Place socket over top of old plug turn counterclockwise and it will come right out After inspection compare appearance of your spark plug with those shown in chart to get some idea about general running condition Apply a little antiseize compound to threads of new plug It is often convenient when installing a plug into its hole by slipping hose over end so you can more easily start threading Install one of new plugs into hole until no longer possible turn by fingers and then tighten On turbocharged engines, inspect ignition coil before pushing it on end of plug. On non-turbocharged engines, inspect wire to the plug. Repeat this procedure for remaining spark plugs.
