Question about Peugeot Cars & Trucks
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.

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

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.
