Noise

[rips4]

I have a 04 f250, and have been experiencing a whinning noise every now and then. The noise goes with the rpms of the engine. It seems to kick on when I romp on it and wont stop until I turn the engine off and it cools down?

Any ideas?

Thanks

When the you here that noise stop keep the motor running and check the degass bottle (coolant fill cap) sounds to me like coolant cap is spuing air.Could be head gaskets or egr cooler.Maybe a tech can pin point thisone
