Engine cooling fan run on
High there! Can anyone suggest cause of engine fan running continiously. Sometimes after journey, switched off engine and fan would run on, expecting it to shut down within 5-10 minutes. This would be still running 30 minutes later and continue to flattern battery. I have to remove earth cable from battery to stop this. when reconnected the fan will start up again, even when engine cold. Following a journey, switch off engine and the fan is silent, everything seems O K again, but on experience this condition returns again sooner or later. I have checked coolent sensor on cylinder head and expected when unpluged would create open circuit and stop fan , is there something I am missing ? I would be gratefull if anyone can shed any light on this problem please, regards Alan Rendall.
