Instructions

    How to Remove a Tight Oil Filter

  1. 1

    Lift the vehicle to locate the oil filter (on a car lift or with a floor jack and jack stands). In some vehicle makes (GM is a common one), a cartridge filter can be located in the engine compartment below the plenum. This would require a socket type removal tool with a square drive to fit an extension and a ratchet to remove. Those the cartridge filter sits inside the housing, this type is uncommon to over-tighten, but will require the tool regardless due to the lack of room.

  2. 2

    Locate the oil filter on the vehicle and determine which tool will be best to remove the filter. With filters in awkward locations, there are a variety of tools to remove it correctly if you cannot remove it by hand.

  3. 3

    Place a cap socket with a square drive on top of the oil filter. It will fit the filter snugly. Insert the extension and ratchet to the square drive. Turn it counterclockwise to remove the filter.

  4. 4

    Use a swivel band strap if the position of the filter does not allow access for a ratchet with a straight extension. The swivel band strap wrench wraps around the filter and the handle can be manipulated back and forth to allow leverage in different positions. Pull the handle counterclockwise to remove the oil filter.

  5. 5

    Use the pliers type wrench in tight areas to access, but still allow some room perpendicular to the filter. This type of wrench wraps around the filter like a large set of pliers. Crushing the filter or slipping is common with this type when trying to remove an over-tightened oil filter.

  6. 6

    Place the nylon strap type filter removal tool around the filter and wind up the strap counterclockwise until it is snug against the filter. Insert the extension attached to the ratchet into the metal square drive brace and turn the filter counterclockwise to remove.

  7. 7

    Install a spider-type or cam-action filter wrench onto the filter and insert the extension attached to the ratchet into the square drive of the wrench. This type of wrench covers the bottom of the filter and is locked in a removal position by a cam. Remove the filter by turning it counterclockwise.

  8. 8

    Inspect the oil filter base threads and flange. Make sure the threads are not damaged by the over-tightened oil filter. Make sure the gasket of the over-tightened oil filter has not adhered itself to the flange. This will cause a leak when the oil pressure rises during operation. Remove the gasket if it is still present and wipe the area clean of oil.

  9. 9

    Apply a light coat of oil to the gasket of the replacement oil filter and tighten by hand. Never tighten an oil filter with a wrench and do not over-tighten an oil filter by hand.
