You may have a cracked cylinder head or damaged head gasket.
Open the coolant bottle and rev the engine, if you see bubbles and get an exhaust has smell then you probably have trouble.
Unless you are very mechanically inclined or better yet a mechanic, it’s not recommended you try fix it yourself.
If you don’t pick up any bubbles or exhaust gas smell, you may have a blockage or even an airlock in your cooling system

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

SOURCE: Peugeot 206 temperature gauge not working?

it could be a couple of things, first, check the wires to the temprature sender unit make sure they have not broke, as it was sudden this may be it, also it could be the sender unit it self as a freind of mine had with her car i changed that and the one for the radiator switch, but most of the time it will be something to do with the sender unit on the engine...hope this helps

SOURCE: 2000 focus temp gauge fluctuate

Hello, on your model the Head sensor sends a signal thru a resistor pak and the ECU. If the fan runs on high speed when you turn on the A/C then the resistor pak is good. If the resistor pak is bad neither of the fans will run when the A/C is on. Change the resistor pak.

If the fan runs on high with the A/C on, then the head sensor is not indicating a high temperature condition when the A/C is off. The A/C switch overides the head sensor. The head sensor is on the Passengers' side of the car above the Alternator. The head sensor is not throwing a signal to start the High speed fan. The head sensor is a long pin screwed into the head at that location.

While you say the fan is working, it may not be working well enough because of the head sensor.

Peugeot 206 temp gauge issue

Make sure the coolant level is correct. If it is, could be a bad water pump or a clogged radiator. Check the radiator to see if it looks like the inside has a lot of scale and deposits. Remove some coolant if necessary. If the radiator looks relatively clean , could be a bad pump.

My peugeot 206 temp gage gos into the red and warning light comes on

they either did not put new fans on or they did not connect them correclty its all in the fans the fans cool the water for the engine when it cycles through the engine it cools off there at the radiator and it takes longer to heat up cause allways in any car when you turn on the ac it will turn high or secondary speed on fan so it cools the water even more so check fan if they replaced it motor might be bad or again check connections

Heater gauge goes past the middle part and many times fluctuates...

Check for low coolant, with an intake gasket leaking. Most of these I see have an intake gasket leaking coolant which when the coolant gets low, will run hotter and fluctuate the temp gauge.
