So, a few days ago my temperature gauge started reading high...but then sometimes it wouldn't even register. My temperature on my car has always been fine up until now. A few days after my gauge went on again off again, the car overheats. It has also been loosing power, it seems. I was told to change the thermostat. What do you think? I have a 1990 Nissan Sentra.

Your coolant level may be too low - or perhaps you have an air lock that's stopping the coolant from touching the temperature sensor. If the car's running low on coolant, it can overheat without the gauge going up at all - in fact, sometimes it actually goes down. The sensor needs to have coolant touching it to register the temp - being surrounded by hot air doesn't make it work. It's also possible that your thermostat is jamming. When it jams shut, the car gets too hot (overheat), and when it jams open, the car cools too much (runs cold.)
Good luck!

The thermostat is probably stuck closed and this causes a car to over heat, but the temperature gauge going hot then cool means that your water in the engine is low and you need more coolant!

An motor vehicle cooling equipment must be drained, flushed and wiped clean with powered acid cooling equipment cleanser to get the rust and corrosion out. in no way use low fee save antifreeze in any vehicle outfitted and inclusive of the year 1994. Take your VIN code to a Lexus or Toyota broking to get the spectacular antifreeze, one hundred% organic if in any respect achievable. Fill a million/2 the full potential of the EMPTY cooling equipment with one hundred% organic antifreeze first. Fill any last area with distilled water.

Sounds like thermostat is stuck it opens and closes do to temp in motor it would be cheaper to change it your self make shure you get new gaskets for it also.

your cooling system is loosing coolant somewhere......it read,s hot when coolant touch,s the sensor......but read,s nothing when coolant drop,s enough so it doesn't touch the sensor......a cooling system leak can be enough in itself to cause an overheat situation.......your thermostat must be covered by coolant to function properly.....check your coolant level....then go to the nearest radiator shop to have your system pressure tested......good luck.

WATER PUMP or cracked block or blown head gasket do you have power? the termostate wont make you loose power just over heat

STOP all these guessing games and take your car to a RADIATOR SHOP and get it fixed.
