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
check the cooling fan sensor somewhere attached of the fan housing.
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 can find the 1991 Buick Skylark radiator drain plug on the bottom of the radiator. The radiator drain plug will be in the center of the radiator bottom.
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)

The most common causes of engine overheating (in no particular order): 1) Blown head gasket - fix = replace blown head gasket; 2) Blocked radiator core - fix = chemical clean &/or radiator back flush; 3) Stuck thermostat - fix = replace thermostat; 4) Faulty water pump - fix = replace water pump; 5) Non-functioning cooling fan(s) - fix = check wiring to fan(s) &/or thermo switch; 6) Broken / loose fan belt - fix = replace or tighten fan belt; 7) Lack of water / coolant in radiator - fix = top up radiator; 8) Retarded ignition timing - fix = check / adjust ignition timing; Hope this helps!
Need more information, is the fan just not working? I would first check the fan relay and temperature switches.

Before you fix the Fan Relay, look for a "RAD FAN" fuse (30 amp - orange). Normally, the computer diagnostic shows the problem is the Fan Relay, but, in my case was the Radiator Fan Fuse ($5). I waste $60 paying for the Fan Relay :-[
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
Open hood . Lean over, Look down for fan blades. The radiator is in between you and those fans. Look fer it. There is a filler cap on the left top of the radiator. Check the water while you are at it.
Check the temp sensor. Also, if the AC compressor is on the radiator fan will be on, so turn off the defroster and the AC.
No, the radiator fan is electric.No, the radiator fan is electric.
