Follow your upper radiator hose from the radiator to the motor, you'll see what looks like a little nut with what resembles the nipple on a baby bottle on top of it, let the car warm up then SLOWLY open that (it's a 10mm box end wrench I believe) and wait for the air to finish coming out, then a small trickle of coolant should flow out, then close it again and the system is bled, just check your coolant level again (after the car cools) and make sure it's full still

 

i fixed it, it was the condensor fan, thanks
