if you don't have the infinty system installing an after market stereo is very simple. just pop off the frame around the stereo (it has the climite controls on it as well) there aren't any screws it just pops out and then there are 4 screws to remove the deck from the frame around it. there is also a very nice blot for grounding if it is needed. however where it used to say the radio information it will now say "E Com" I'm working on how to fix that one still.
Safely jack the car up, remove lamps,replace bulbs.

No. It's not interference engine.
the speed sensor for 2004 Mitsubishi Galant is located on the front case of the transmission output shaft and speed sensor. It is approximately under the hood to the left of the engine.
The strainer valve on the Mitsubishi Galant 2004, 2005, 2006 models is located next to the engine manifold.

Can you? Yes. Should you? NO! Use exactly what Mitsubishi recommends and that is not 15w40.
Low refrigerant? Blown fuse?
The problem is probably the rear wheel bearings
