Driving into work this morning the Alternator light comes on. Then the Engine Temp Hot light comes on and the temp gauge is in the red. As soon as i started to pull off the road to shut the car off both go away and temps drop to normal. further down the raod it happens again and again till the Battery Saver Mode comes on and i loose power steering. Why would an alternator issue cause the temp issue? do I have more then just a bad alternator. Any help with this issue is app is appreciated
