The Ford Fusion was introduced in 2006 and could either feature a 3.0-litre six-cylinder engine or a 2.3-litre four-cylinder engine. While both engines use 5W-20 replacement engine oil, the replacement oil filters are widely different between the two. The four-cylinder uses a cartridge-style filter while the six-cylinder uses a canister-style filter. The amount of replacement oil needed between the two engines is also slightly different.
Drive the Fusion slowly up onto two car ramps. Apply the parking brake.
Open the bonnet. Remove the oil fill cap by turning it counterclockwise. Place it in a safe location so you do not lose it or drop it in the engine compartment.
Put on the safety glasses and latex gloves. Grab your tools and equipment except for the funnel and engine oil. Crawl under the front of the vehicle.
Place the drain pan beneath the oil pan. Remove the oil pan drain plug with a metric box-end wrench. Make sure you align the pan properly. The oil is going to come out fast at first and at a slight angle away from the pan. Allow the oil to drain until no more is trickling or dripping from the drain plug hole.
Replace the oil drain plug and tighten it snugly. Do not over-tighten it. Turning it flush to the pan and then about 1/4 turn of force with the wrench should be sufficient. Wipe the pan and any surrounding area with spent oil on it with the shop rags.
Remove the oil filter trap door in front of the oil pan.
Align the drain pan beneath the oil filter. Remove the filter of the 3.0-litre with an oil filter wrench by turning it counterclockwise until it is loose enough to drain. Allow it to stop trickling before you remove it fully. Remove the centre oil drain plug from the oil filter casing on the 2.3-litre using the 6-mm hex-head male socket, an extension and the ratchet. Allow to drain.
Obtain the oil filter drain plug replacement gasket supplied in the replacement oil filter box. Remove the old one from the plug, and install the new one. This is for the 2.3-litre model only. Replace the oil filter casing drain plug and again tighten it snugly. Do not over-tighten it.
Remove the oil filter casing of the 2.3-litre using the ratchet, extension and the 74mm 14-flute oil wrench socket. Turn the casing counterclockwise until it is fully removed. Reach up and pull the filter straight down. Sometimes, the filter comes down with the casing. Remove the 3.0-litre filter by continuing to turn counterclockwise until it is fully removed.
Replace the large O-ring gasket on the 2.3-litre oil filter casing. This is also supplied in the replacement cartridge oil filter box. Rub a small amount of oil on the O-ring gasket of the casing or the rubber gasket on the 3.0-litre replacement filter. Be sure the old gasket is not still stuck on the oil filter flange.
Reinstall the respective oil filters for the engine size of the Ford Fusion by reversing the procedure. The canister filter should be tightened by hand only. The oil filter casing should only be tightened snugly like the drain plugs were. Wipe up any spills or drips with shop rags.
Place a funnel in the oil fill hole and pour 4.8 quarts of 5W-20 oil for the 2.3-litre or 6 quarts of 5W-20 oil for the 3.0-litre. Pour the quarts in slowly so you do not overflow the funnel or oil fill spout.
Replace the oil fill cap. Tighten it in a clockwise motion.
Start the ignition. Allow it to run for 30 seconds.
Remove the oil dipstick (yellow ring handle in lower front passenger side of engine). Wipe the dipstick clean with a shop rag. Reinsert it into the dipstick tube. Make sure the dipstick is fully seated in the tube. Remove the dipstick and inspect the end to make sure the oil capacity is in the "Safe" range (markings on dipstick are easily identifiable).
