Maintenance DIYs? Spark Plugs, Fuel filter, etc.
 

I'm trying to help my brother with his 2000 3.8L mustang, but I can't find any online guides on any basic maintenance for this car. I'm looking for radiator flush, fuel filter, and spark plug guides to name a few. I have a 95 M3 and online guides are really easy to find for that car, I just assumed that the mustang would have a much wider following and it would be easier to find guides for basic stuff. If anyone knows, can you shoot me an email at sadiq.ansari@gmail.com.
