For the last couple of weeks my car has been driving me no where but nuts !! First I noticed that the battery wasn't recharging because I got stuck when all the lights dimmed and the car died. So I replaced the alternator. Car worked good for about a week then did the same thing. So I replaced the battery at which time the alternator checked out good. Now when I go over 40 MPH the temp starts going Towards 120c the faster I go the higher the temp. If I stay at 40MPH the temp stays at 80c? Now the battery is also draining again but the charger says the alternator is good? Also have a loud squelling noise, the faster I go the louder it gets ?? Can someone please help me?? I really love the car when it s running !!
