here is how to change your oil filter
Just changed mine for the 1st time on 2008 nitro. Took 20 minutes. Here's exactly how you have to do it. You must lay perpendicular to the car with your face on the drivers side and feet on the passengers side. You must remove it with your left hand. Because of the way the arm bends and the lack of openings in the truck, this is the only way to get in there. It's about 5 inches higher than the bottom of the radiator and go toward the back of the truck from the radiator about 6-8 inches. It is in there at a slight angle, not straight up and down. There is only room for one hand and if you try it with your body the other direction and using your right hand, you will probably never get it. Buy a filter that says secure grip. they have a real tacky easy to grab material coated on them. This will help you tighten it. The oil drain plug is the super easy part.
