I do this:

1. Replaced cooling temperature sensor for fan acting.
2. Cleaning radiator. Disassemble clean an reassembled.
3. Get out thermostat but still overheating.

Hello,

Have you checked the water pump? Usually there is a hole on the bottom of the water pump called a weep hole. It is designed to leak coolant when the water pump fails. It does this because the shaft will get sloppy and it let's the coolant leak out before it reaches the bearing causing it to seize up. If you have coolant leaking here the water is bad and needs to replaced. From what you have already done I would suspect a bad water pump. Here are a couple of links below for you to go to:

Please go through these guides and get back to us with what you are able to find out.

Thanks,
