Check the Engine Coolant Temperature Sensor (ECT) If the sensor wiring is unplugged the cooling fan will run continuosly. This won't nesesarily mean that the sensor is at fault, it could be a wiring harness fault.

thank you for your reply coolent sensor renewed and renewed another relay all good at moment but it just happens at random, i could go out and start it from being left overnight and coolent fan kicks in its a strange one that noone can sort out

I would check the wiring harness plugs related to the cooling fan and the cooling fan controller (if it has one) Once these vehilces get older, some of the harness plug connectors have been known to play up or the female terminals expand, so you don't get a propper connection. If would also check if there are any fault codes with a diagnostic tester so you can receive a more accurate fault finding. This will also show up intermittant faults.
