Guys can anyone help?ive purchased a new mishimoto fan after my old packed up,I lost coolant at the same time so have filled it up back up,I am finding small air in coolant which I'm slowly shifting but can anyone tel me if both fans come on together or if there's a sequence,the drivers side is coming on when car get up to temp and also when air con is on but the passenger side doesn't seem to be doing squat,I'm wandering if it's still cZ of air in system or should they both come on together
