Hey there, I have a 2003 C3 with Petrol+LPG. Most of the time the fan runs completely fine. But sometimes the temperature signals on the dashboard start lighting and dropping down to 3 level like an alarm to show that its not working, its not overheating as I am understanding but just seeing this signal and a little beep for alarm, then i have to open the hood disconnect the cable that has two thick wires and reconect them again and it start working. What am i dealing with here? Hoping someone can help me!

Is the level of the coolant in the coolant container between the mini and maxi marks when the engine is cold?

Would it be a problem if it is more than max. I mean when it is cool the level is NEAR MAX, Could it be a problem if while running it increases?Arfur Dent wrote: ↑Tue Jan 19, 2021 9:44 am

The green coolant outlet temperature sensor on the thermostat housing are known to fail.
You could try replacing that.

No, not a problem if it a bit high, not enough to cause you a problem like this.frankoprifti wrote: ↑Tue Jan 19, 2021 11:08 amWould it be a problem if it is more than max.

A low level can give flashing temperature lights. The sensor on the side of the tank with mini and maxi marks is the sensor. They can become contaminated with oil when the head gasket fails. The sensor is easily removed, but you will loose some coolant.

There are many different fan systems fitted to the C3 models. You will need to identify the fan system you have fitted. They are often computer controlled, so you need a good understanding of what you are doing without doing even more damage or bringing up more error codes.frankoprifti wrote: ↑Thu Jan 21, 2021 6:39 pmCan someone tell me how can i run the radiator fan manually with a switch?

As Arfur says, there are a couple of different versions of the fan assembly and I would need to know which version you have.frankoprifti wrote: ↑Thu Jan 21, 2021 6:39 pm Can someone tell me how can i run the radiator fan manually with a switch?

You will find the the thermo fan will run at full speed each time the display goes mad, but will run as normal at all other times. So if you are intending to install a switch to cut the fan off...that's not a good idea. You run the risk of forgetting that you switched the fan off and could over heat the engine.
I still recommend replacing the temperature sensor, it's simple and not that expensive. Installing a switch will not stop the display going wild or the car beeping at you.
This is the type of sensor you are looking at but you should confirm the engine type and year.

I want to install a switch that turns the fan on manually for the times that the coolant temperature switch doesnt do its job. So i dont have to open the hood and disconnect and reconnect the wires to make it work.Ozvtr wrote: ↑Thu Jan 21, 2021 10:08 pmAs Arfur says, there are a couple of different versions of the fan assembly and I would need to know which version you have.frankoprifti wrote: ↑Thu Jan 21, 2021 6:39 pm Can someone tell me how can i run the radiator fan manually with a switch?

Of course I'm going to change the sensor but as long as I'm not too sure which part is having the problem in my car, I want to be sure and add a switch so till I find the problem I have the option to manually start the FAN to prevent overheating.
