My fan won't turn off

The ac fan only comes on when the ac is on , the engine fan comes on at engine operating temp . few things to check , the radiator core fins are free from rubbish leave or plastic bags , the thermostat is fully open , radiator tubes are blocked with gunk have it flow tested .

the usual suspects are:
stuck shut thermostat
clogged raiator
dead water pump
low coolant level
it's sunday, rovers don't work on sunday.
Then again, maybe its wednesday, rovers take half a day then.

natural for engine temp to rise in Traffic - Until Themostat opens ) cooling fan sensor kicks on fan . But Antifreeze is not just a Cold weather item . Coolant is Absolutely Necessary for Hot Days . You must be full to recovery bottle setting of cold when checked prior to start up . Coolant for your make / model is Reddish - Pink colour and should have a reading of -25 thats negative 25 degrees the Lower the Better even - 50 .. Why ?? - 50 is 50 %% antifreeze / Coolant Concentrate MIX Gives Hot weather cooling Ability or very cold weather starting / winter HEAT .

Wait till the engine is cold, remove the radiator cap, start engine and look for coolant gushing out of radiator or a lot of bubbles, its possible you have a blown head gasket.

The gauge or sender or wiring in defective or in need of repairs.

Could be a thermostat stuck closed or a bad water pump.

first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure

It is normal for the fan to cycle between on and off even though the temperature gage reads normal.
Anytime the coolant temperature rises by approximately 10 degrees above the normal operating temperature the fan cycles on but you won't notice the gage show that small of an increase.

Check your thermostat and check to see if the electric motor has power or not may be a damaged wire or a fried fan motor,you can also check the fan motor by running a power lead from your battery.good luck
