Hello I have recently replaced thermostat plus flushed radiator and filled with new coolant.I note that only one fan is running not two to cool engine. However when the temp gauge gets towards the upper limit the other fan is working so both are running?Is this normal. Or should they both cut in at the same time. My car is running hot and I am trying to eliminate promblems any assistance would be appreciated.

Could be airlock try bleeding it and see what happens. The fans are doing their job if it continues to get hot get it block and pressure tested.
