My sonata has the temp guage reaching just under halfway. The radiator was full of rusty water. I took out the thermostat that was rusty with a melted seal. Usually do this with most of my cars dont really like to keep the thermo in. Anyway I drained out the radiator untill clear water water come through. Also the block, did it with a hose. After doing this I filled it with coolant. The next day I opened the cap and still had thick blobs of rust in the water. Also I dont think the fans are working. What could be the problem?

First off, you must have a thermostat. It is critical to the even temp of the motor.

You need a radiator shop to power flush it with acid to get all the rust out.

Then you must maintain the system and change the coolant on a timely basis.

Get the cooling system correct first. The sensor may be getting false readings from the rust, once it is clean it all may come back on line
