5. Clean sealing surface on engine where filter mounts.
6. Coat the seal of the new oil filter with clean engine oil.
Install new filter first by hand until it contacts the engine
sealing surface. Tighten it another 3/4 turn using the
filter wrench.
7. Fill engine with oil until it shows between the upper and
lower limits on the dipstick. Do Not overfill.
8. Run the engine briefly for several minutes. Watch for
oil leakage. Shut the engine down and allow it to sit
for several minutes. Top off the oil to the upper limit on
the dipstick.
