How to fill radiator on citroen c3

SOURCE: Coolant fill procedure

NEVER open the radiator when the car (or any other engine) is running!! The radiator is part of the pressurized cooling system (under that cap is coolant at 15psi)

Correct way to check the coolant in the radiator, is wait until the engine is COLD, then remove the radiator cap and re-fill.

SOURCE: Low Coolant light stays on

Check you coolant resevoir. The low coolant switch is located in the resevoir so if it is low on coolant there, the light will come on. If it is full, it could be that the switch is stuck due to gunk build up in the resevoir. Hope this helps you out

SOURCE: coolant in coolant reservoir did not fill low level in radiator

you must drain air out of system
so when engine is warmed up, just unscrew slightly the thermo time switch which is the highest sensor and unit in cooling system besides the reservoir, until alittle air releases then when antifreeze starts coming out then retighten to specs. BE VERY CAREFUL !!!! LOOSEN VERY SLOWLY AND NOT COMPLETELY REMOVE FOR THIS CAN CAUSE BURNS. MIGHT WANT TO USE A RAG AROUND SENSOR. If this doesnt solve it then make sure you have the correct rad. cap. Also that the filling hose is not clogged as well as the little port on radiator.

You need to have a computerised diagnostic done to it to get an error code and take it from there...

The sensor is on the radiator just below the cap about 6 inches or so.You can either drain it down below the sensor and replace it or just remove the sensor and install the new one.It is held in by a metal spring clip.Just remove the spring clip and pull the sensor out and install the new one.Make sure you do this with the engine cooled down.Hope this helps.Good luck.
