I get a roaring noise from my ...or Our 7.3 sometimes, early in the AM and pulling a grade (worst). When I get on flat land it goes away. Like I said, it is sometimes only except for one mountain and then it does it everytime. Also in slow city traffic in town when it is hot out.Any ideas?
Thanks in advance!

The radiator fan has a thermal clutch. When it gets hot enough, it
fully engages the radiator fan. That is what you are hearing...
Noisy, isn't it?
