    Change your thermostat immediatly as in ASAP.

    The thermostat is stuck closed by all accounts. What this does is traps the coolant in the engine block itself. As the engine gets warm the thermostat will open allowing cool coolant to drain into the engine and push the hot coolant into the radiator to cool down. This is not happening so the engine is boiling away the coolant trapped inside. The engine is getting so hot the fan is cutting in to cool it down. However the fan isn't designed to cool the engine down its designed to push cool air through the radiator to cool down the hot coolant. As your thermostat is stuck closed its not doing that. Worse case senario is your going to warp the head on the car (if you haven't already done so).

    Get it looked at ASAP.

    Hi m8,if your cooling fan starts running as soon as you start then you have a problem with the cooling module.this is located behind the front bumper on the nearside(you may have to remove the w/arch liner to access it)check the plug for poor/dirty connection..if the connections are good you may need a replacement module
