good evening
while sitting in traffic today temp gauge went into the red and steam from under the bonnet,left in parked for a couple of hours then got it home,all ok while moving probably because its so cold today,just had a quick look again left it running on the drive once again temp goes right up and the heater in side the car only gets luke warm would this be an air lock ? the other thing i noticed is that the radiator fans do not come on
any advice is more than welcome
