Saab 9-5 oil/filter change
This is probably a basic routine procedure for many but can still be intimidating if you have never done it before. This posts covers the 2.3T / 2.3t engine.
Tools needed:
- wrench/spanner or ratchet/socket 13mm or 1/2"
- oil filter wrench/cap/pliers
- funnel (optional)
- latex gloves (optional)
- car ramps
- container for draining the oil

A new drain bolt is optional if the head on the bolt on your engine is worn. Size is M14x1.5 .

See this thread for oil specifications: link
Difficulty rating (1-5): 1 - Easy
Time estimate: 1/2 hour
Note:
My car has a drain bolt size of 13mm. I ordered a replacement bolt which is 1/2". I have seen other US owners mentioning 1/2" for he Saab 9-5. These 2 sizes are very close and you shouldn't have a problem using a 13mm or 1/2 wrench for either bolt, unless it is really tight.
Instructions:
Make sure the engine is warmed up before you start. Wait 10 minutes or longer after the engine is turned off so most of the oil drained back to the oil sump. Warm oil drains easier.
Use car ramps to lift the front of the car.

The oil filter and oil drain bolt are located to the left of the exhaust when looking from the front of the car. The drain bolt is at the back of the oil sump so it can not be easily seen.

Drain the oil. Turn the wrench/spanner to loosen the bolt in the direction as indicated. This may seem the wrong way but remember you're looking at the back of the bolt.

Remove the oil filter. Make sure the old rubber gasket comes off with the old filter.

Let all oil drain out. The longer you wait, the more will drain.
Fit the new copper washer and tighten the drain bolt. Tightening torque is 25 Nm / 19 lb ft.
Make sure to not tighten it too much. It's possible to strip out the threads in the aluminum oil pan, and another possibility is leaving the plug so hard to remove that the bolt will get rounded if not removed by a 6-point socket.
Put some fresh oil on the rubber filter gasket before you put it on the engine. Be careful how much you tighten your oil filter. Tighten by hand first and then a quarter turn or as suggested by the filter manufacturer.

Put 4 quarts of oil into the engine. Hold the bottle this way so no vacuum gets into the bottle when you pour the oil.

Start the engine and check for leaks from the filter and drain bolt. Let the engine run for a few minutes so oil can soak the oil filter.
Stop the engine, let it sit for 10 minutes and check the oil level. Add more oil if needed. I have done many oil changes and found 4 quarts is just the right amount.
Don't Over Tighten oil filter.
Tried out your oil and filter change instructions. Overall, very informative for a novice like me. I have a suggestion for anyone who follows these instructions:
1. Be careful how much you tighten your oil filter. It should be only hand tightened and then a quarter turn or as suggested by the filter manufacturer.
I have had the unfortunate experience of over tightening, and damaging the filter. I did not know the limitations of the filter.
