How to service a cartridge type oil filter on Mercury Mariner?

Service of cartridge type oil filters demands that you position the vehicle in neutral on a hoist and proceed with the steps. Begin by using a cup-style wrench to modify the oil filter adapter drain plug until it uncorks along with opening the oil filter cover by one turn. The service procedure requires users to remove the drain plug from the oil filter to eliminate engine oil from the adapter and filter while disposing of the broken drive plug O-ring seal. Move forward by removing first the oil filter cover and after that its element which you must discard both items together with their O-ring seal. Clean all surfaces on the adapter mounting bracket as well as the oil filter cover before applying clean engine oil to the oil filter cover O-ring seal. Then install the new O-ring seal. You should position a new oil filter element properly along with the oil filter cover while using the cup-style oil filter wrench to tighten them to 33 Nm (24 lb-ft) but avoid over-tightening since this could potentially harm the components. You should lubricate the new oil filter drain plug O-ring seal with engine oil before installing it. Afterward, join the drain plug but tighten it only to 10 Nm (89 lb-in) to avoid breakdown.
