i have a Citroen c2 vtr 2004 model. I've noticed for the last 4 days now my engine temperature gauge started to climbed to three bars even when 20 minutes distance trip and not even using the heater. when i checked the hood while engine is running i noticed the radiator fan is not running and when i turned on the heater the fan is still not running. whats wrong?
TURN THE AIR COND ON THIS WILL ALLOW THE FAN TO COME ON,THERE ARE TWO THINGS IT COULD BE ELECTRICALLY ,UNLESS THE FAN MOTOR IS BAD .ONE IS FAN RELAY,TWO THE SENDING UNIT THIS TELLS THE RELAY THE ENGINE IS HOT ENOUGH TO FEED THE RELAY,THUS SENDING 12 VOLTS TO THE FAN.THE MOST COMMON PROBLEM WOULD BE A SENDING UNIT AND OR RELAY,TAKE A PIECE OF WIRE AND GROUND THE SENDING UNIT WITH SWITCH ON, IF THE FAN COMES ON YOU HAVE A BAD SENDING UNIT.LEAVE THE SENDING UNIT PLUGGED UP,GROUND IT BY TOUCHING THE SENDING UNIT TO A PIECE OF METAL SUCH AS A BOLT HEAD OR NEG.SIDE OF BATTERY.
There are a few ways you could make your radiator fan turn on. You could fix the wiring for example.
Sensor is likely bad
Check the thermostatic switch
Check at the rear side of the radiator towards the top
depends what needs to be fixed and how badly the parts are damaged
How to fix heater in Buick there is cool air ,fan is work .but no warm air
check the cooling fan sensor somewhere attached of the fan housing.
REar side of radiator approx. 1/3 from the top
The radiator cooling fan will run to cool the radiator to below the fan turn on temperature. You may want to have your cooling system checked if it happens regularly as your Buick may be running hotter than normal when driving.
You will have to be specific about which fan you mean- the radiator cooling fan(electric or mechanical) or the heater fan. It might help too if state what is happening(or not)
Need more information, is the fan just not working? I would first check the fan relay and temperature switches.
