I would guess that the thermostat is not opening at the proper temperature. Once it does open proper circulation brings it down to the correct operating temperature. I think it should be replaced.
If it overheats at speed, but cools down when you slow down, the problem is likely a head gasket. Combustion gasses are leaking into the cooling system, adding bubbles (which take the place of coolant) and extra heat. Slowing down means the engine is spinning slower, and less combustion gas gets into the cooling system.
Could be a leak in the head gasket. From the cylinder to the coolant chambers. Have your cooling system pressure checked.
You might want to check and see if the electric coolin fan is working. Also it could be your thermostat not opening and closing when it should.
Water in your sweat cools you down.
After it cools down
because the sweat is water and water cools you down so that is how sweat cools you down
every muscle, when we sweat that cools us down, the hairs on our body stands up and that cools us down. everything cools us down
igneous rock is formed when lava cools down
Is your radiator full? Have you got a leaking head gasket?
No.
Lava cools in the ocean waters. It will also cool down as it moves.
What makes you think it's the temp sensor? It sounds more like a stuck thermostat, faulty water pump or plugged radiator.
