1989 Dodge Aries Overheating

If it overheats while driving more than 25 miles an hour, the thermostat is bad. If it overheats while stuck in traffic only, either the fan motor or the temperature sensor/switch that controls the fan to operate is bad. This temperature sensor/switch is installed on the radiator. It screws into a threaded hole.

replace your thermostat and check the waterpump. The ac "pulls" heat out of the air in the car thereby making it cooler, at the expense of making your coolant heat up even quicker than normal. Try this to see what's going on.. Open the radiator cap, start the engine and wait until the car gets up to operating temperature. You should be able to see the water circulating through the radiator...if the fan comes on, and the water isn't moving, then replace the thermostat. If it still isn't moving after that, the water pump may be no good. Id bet on the thermostat. They're cheap and need to be replaced every so often. If the water is circulating and the fan never turns on, then you check the fan motor, relay, etc. There is also a temperature sensor located somewhere next to the thermostat. It's rare to have to replace that, but if it's faulty, then the fan won't turn on and thus overheating occurs. I am assuming here that if you drove your car up a hill without the ac on, it will overheat or get hotter than normal...So....go test your circulation first and let me know what you find. Oh yeah, when you do the circulation test, turn your heater in the car on full blast too...does it get hot inside the car?

Do the electric cooling fans turn on ?

To replace the AC Evaporator core you must remove the dash from the car, a very complicated job, a factory manual is not an option here. You can access the factory manuals for a fee at this site www.alldatadiy.com, it is what shops use. The job takes about 12 hours at home.

the problem is in your dash. you are going to have to replace the battery in the instrument panel.
these will control the opening and closing of your thermostat. i bet that you are having issues with your tach and possibly fuel consumption. once you do this you are set.

Unless water pump bearing is loose or noisy or the pump is leaking, that's not your problem. Have the system flushed. Thermostat is also likely not the problem but with repeated overheats or near-overheats it will become unreliable so change it as a precaution.

Sounds like a stuck thermostat. Replace the tstat and flush the cooling system. Replace the anti freeze/ coolant.

maybe the sensor that turns on the fans might of gone bad . . and turning on the ac when engine is gettin hot is not going to help instead turn on the heater to reduce the heat , also overheating causes hoses and gaskets to get soft and get destroyed

you just said it you need a new fan clutch
