I have a 2004 Dodge Stratus SXT 2.7L. The miles are high, 184000. I didn't have any major problems with it, only changed the thermostat, air coolant bleeder and a lower radiator hose. Also changed the ignition switch a while ago. It runs great but I don't want it to die when I will need it most. Any suggestions on what I should change on it? Thank You.
