Weird noise under hood

(2008 Ford F-350 Super Duty)
I bought A 2008 F350 at a buy here pay here with 190,000 miles on it . It's only been about 10 days I have no warranty so I have to go to my own mechanic but after a few days I started getting this fan noise like a air blower under the driver side of the hood but it's not constant
, it's only if I'm stuck at a red light for too long and start to go again or sitting in park and then I'll go again but it stopped after a few seconds but even if I put the pedal to the floor the truck doesn't go like it should I tell that fan sound goes away. Well this morning I went to the gas station came back out and let my truck on in my temperature was almost in the red and I just had all my fluids checked about five days ago and everything was good. Any thoughts and I'm praying it's something cheap because I don't have a lot of money and my mechanic doesn't have an opening until the 17th

The noise you describe is the fan clutch being engaged to cool the engine. This is usually is because truck is reaching high temp. but the overheating is a big problem and it explains the fan engaging at high speed often. so you need to stop driving it!!! We can assist you in determining the cause of the overheating. calls us we can get you in next week. 239-424-8477 ask for Rae

Are you a truck repair shop? I'm on my phone at work so can't go online to look. And I'm not gunna shop around if you are but do you know how much something like that usually runs? I was praying it wasn't tranny cause that's why I got rid of my other truck.
We work on just about anything and i have more experience then i want to have with your particular truck. I would not suspect transmission problem i think its in the cooling system of the truck. known problems that can cause that are leaks, bad thermostats. with that said if you over heat the truck you can make repairs in the thousands so its best to have it towed unless you have coolant in it and its not leaking out. As a general rule of thumb working or repairing any diesel truck is pricy they are not fun to work on at all(from experience).

Ok; I'll call you in about an hour or so. Unless you wanna tell me when I can bring it in. I work tomorrow til 12:30. And a estimate of what you think may be wrong
Well we work mon-fri so tomorrow will not be a good day for us. Monday will be a better day.
Have you noticed if the coolant level drop and further after you added coolant?

Yea I've had to put in 2 things of coolant since yesterday. So it'll be in the driveway all day Sunday and today when I get back to work. This same thing happened back when I had an Altima and next thing i knew some of my heads blew one week after another. That was a 06 Altima tho

It sounds like your thermostat may not be opening up to cool the engine. We recently did a repair with very similar symptoms on a 2006 F350 at our shop, the repairs and diagnostics were a little over $150 with a warranty.
