My 2011 Chevy Aveo is heating up but there's no leaks just water is evaporating. Could it be the temperature sensor(s)?
I would check to make sure the cooling fans are working. If they are not working check the fuse and the temperature sensor. You may need to replace the thermostat and flush the engine and radiator out.
I already have done all that. Just wondering if there should be a check engine light on if the sensors are bad. Cause there's not. And engine is making a funny noise.
What kind of funny noise? You may also need a new radiator if the old one is too dirty.
Had a 01 Mercury Sable doing the same thing car ran great but every two weeks had to add coolent to over flow tank. No leaks on ground or steam from tail pipe. Added some Alumi Seal radiator stop leak to cooling system and that took care of my problem. Now if it does not work for you do not continue to add more hoping it will work that is when you will clog up the cooling system. If your vehicle does not have a radiator cap remove top radiator hose and pour stop leak into hose then reinstall hose this is if you do decide to try it.
