STEP 1
With the engine off, remove the filter using a filter wrench. A large belt-type filter wrench assisted by a power bar can be used to remove a tight filter. Occasionally, chain-type belt wrenches are used to remove tight filters. To prevent hot oil from scalding your hand when the filter is removed, a hole may be punched into the bottom of the filter to allow oil to drain before removal.
STEP 2
Visually inspect the filter base for any damage or warpage. Ensure that the old filter gasket is removed.
STEP 3
Fill the new filter with oil. Pour oil in the unfiltered outer holes of the cartridge (the center filter hole returns filtered oil to the engine).
STEP 4
Lubricate the filter gasket with oil or a smear of grease. This will help the gasket slide on the filter base and prevent the gasket from buckling when the filter is tightened. It is also necessary to lubricate the gasket to enable easy removal during the next service.
STEP 5
Spin the new filter on hand tight. Note the arrows or markings at the top of the filter canister, which indicate how far the new filter should be tightened after snugging the filter to the base using hand force only. Most filters are tightened a quarter or half turn beyond hand tight. Tightening the filter further can potentially distort the filter base, which is often aluminum. The filter can also be damaged and internal leak paths formed if it is overtightened. If the filter is too loose, it will leak.
