If it is a 4 cyl the filter is on thetop of the engine It is a catridge style located in frt of the oil cap down about six inches Black plastic cap
In the 6 cyl the filter is at the front of the engine. Also, instead of looking for a large wrench or socket, use a 3/8 ratchet instead (if you are faced with a round insert, go with the 24mm socket). It will go right into center of the oil cap.
To drain the oil you will need a T45 STAR socket. I would use one with a 3/8 drive. Number of tools needed. Two.
Also, put a little oil around the O-ring when replacing it. It will help to ensure you don't tear the O-ring.
Where is the transmission filter location on a 2003 Saturn Ion
5 with filter change
Place a drip pan below of the oil filter. Attach an oil filter wrench to the filter. Turn the wrench to the left. When the oil filter is loose turn with your hand until it comes off.
4.5 quarts with oil/filter change.
For the 2.2 liter 2003 Saturn Ion:Fram CH9018STP S9018R
Saturn recommends changing oil filter every 6000 to 12000 miles. Most mechanics recommend changing the oil filter with every oil change.
When you change the oil on a 2003 GSXR 600, you need 3.0 quarts of oil if you do not change the oil filter. If you change the filter, you need 3.3 quarts of oil.
You will need 5 quarts to change the oil and filter in a Saturn.
