Tools and supplies you will need:
Jack and jackstands.
12mm socket and ratchet.
Oil Filter Wrench (band type or special Volvo tool).
17mm socket and ratchet or 17mm end wrench.
Oil drain pan.
New filter with o-ring: http://www.fcpgroton.com/product-exec/p ... ory_id/136 or: http://www.eeuroparts.com/Main/PartDeta ... id=1275811 or: http://www.swedishautoparts.com/S80/vol ... lters.html
New drain plug aluminum crush washer (optional but recommended): http://www.swedishautoparts.com/S80/vol ... shers.html
7 quarts of oil (for a T6 - others may take less).
Paper towels or rags.
Funnel.
Small screwdriver.
Torque wrench.
Begin by chocking the wheels, jacking up the front of the car, and placing the jackstands so the car doesn't fall on you while you're under there working.
Now use the 12mm socket and ratchet to remove the 7 bolts holding the undertray to the bottom of the car:
Drop the tray down and slide it out of the way.
Use the 17mm wrench to loosen the oil drain plug located on the back of the oil pan:
Place the oil drain pan under the car and unscrew the drain plug the rest of the way by hand. Hold onto the plug if possible - if not, you'll have to fish it out of the used oil. This shot shows the plug removed with the crush washer on it and the magnet on the end with some metal filings:
Use the paper towels or a rag to wipe off the plug and washer (if you're going to reuse it). Slide the new washer on the plug if you have one. Wait until the oil stops draining out of the oil pan, then wipe off the crush washer mating surface on the back of the oil pan. Screw the drain plug back into the oil pan and tighten with the wrench to 26 ft-lb. Do not overtighten or you will live to regret it when you can't get the plug out for your next oil change.
The next pic shows the oil filter cover and the dished-out area in the subframe that allows you to use a conventional spin-on filter wrench:
Use the oil filter wrench to loosen the cover by turning counterclockwise:
NOTE: If you can't loosen the cover with the conventional wrench, buy the special Volvo tool, available here: http://www.fcpgroton.com/product-exec/p ... ory_id/136 or here: http://www.eeuroparts.com/Main/PartDetail.aspx?id=A261
DO NOT drive a screwdriver through the cover to remove it - you will be buying a new cover for $15 and your car will be down until it arrives: http://www.eeuroparts.com/Main/PartDeta ... id=1275808
Move the drain pan under the filter cover and unscrew the cover the rest of the way by hand. Hold onto it and turn it upside down over the drain pan to drain the remaining oil out of it. Pull the filter out of the cover.
Here is a pic showing the new filter and o-ring, old filter and filter cover:
Now use the small screwdriver to pry the old o-ring up and out of its groove:
Roll the o-ring up and off of the cover and remove it:
Roll the new o-ring onto the cover and down into its groove:
Use the paper towels or rags to wipe out the inside of the cover. Make sure you remove any gunk that may have accumulated at the bottom. Now take the new filter and place it into the cover. Push it down until it slides over the center post in the bottom of the cover:
If you worry about having oil pressure the maximum amount of the time, pour some oil into the cover while holding it upright. Now slide back under the car and screw the cover back into place. The cover says to torque it to 25 N-m (19 ft-lb), which is fine if you have a torque wrench, but if not just tighten it with the wrench until it is screwed in as far as it will go. The o-ring makes the seal, so you only need enough torque to keep the cover from unscrewing. Also, it takes some torque to force the filter over the center post up in the engine. Make sure you get it in far enough that the o-ring is engaged in the housing or you will have a major league leak.
Open the hood and remove the oil filler cap:
Insert the funnel and add the appropriate amount of high-quality oil (I like the full-synthetics like Mobil 1 and Castrol Edge) per your owner's manual (for my T6, 7 quarts). If you added oil to the filter cover before you put it on, make sure you account for that. I usually add about 1/2 quart less than specified, then check the level after I run the engine and top-up as needed.
Pull the oil dipstick out to check the level. Wipe the end of the dipstick off, then reinsert it into the tube and pull it back out to get an accurate reading.
The oil level should be between the two lines on the end of the dipstick:
Replace the oil filler cap and start the car. Make sure the oil pressure light goes out within 30 seconds - if it doesn't, shut off the engine and investigate what is wrong.
Check under the engine for leaks from the drain plug or filter cover. If you have no leaks, shut the engine off and reinstall the plastic undertray.
Remove the jackstands and lower the car to the ground. Check the oil level and top-up if needed. If your Engine Service Light was on, reset it: https://www.matthewsvolvosite.com/forums ... hp?p=50879. You're good to go for another 7500 miles.
Make sure you dispose of your used oil in an environmentally-friendly way.
