A friend of mine has a 1990 Sentra in pretty decent shape. Lately the engine gets hotter than usual in stop and go driving, cools down again when driving normally. Sounds exactly like the radiator fan is not coming on when it should. The strange thing is, the tail light, e-brake and alternator warning lights come on when the temp gets high, and go out again when the temp drops. I'm thinking this is maybe "normal" - Nissan wired up the dash so these lights come on to make sure drivers notice when the engine is getting hot. My friend's mechanic thinks it "may be the alternator" which doesn't seem right to me. Alternator wouldn't explain the other 2 lights, and why would the alternator be related to engine temperature?
