There are generally two signs that the alternator is going bad.
First is the noise. A new noise will begin to be heard. Something like a whining when the car is accelerating.
Second is the smell. You may smell burning from the engine department.
Open the hood and look for the white engine information sticker. It will tell you what size engine you have in liters.
Look on manufacture tag on drivers side door jam it will tell you size of tire
