I can I tell if my water pump is bad in my 2003 mitsubishi montero sport 3.5 liter

drivers side, underneath the car. look at the line coming from the gas tank, and where the line gets bigger and has a metal cylinder in it, that is your fuel filter. a couple of clamps and you can change that thing out in a matter of minutes, and depending on your medel you may have to remove a metal plate to get to it.

Your belt is loose (and it just needs tightening) or it is worn and needs to be replaced. It may look ok but they glaze over; all the little ridges get shinny and slip.
