I see. So you are telling me that when I am pulling up a hill at 50 MPH with 10,000 lbs in tow on a 100* day and my truck starts to overheat with the stock fan that upgrading my fan and adding a shroud won't help keep the engine cool? Because it sure as hell did...

 

You've voided your warranty there Mister.... Lol

.

 

where can I buy a OE fan? I have a flex fan that makes a silly noise.
1966 F100 2wd, 300 I6

 

Probably a few options that I can think of

1. Keep an eye out of eBay (I posted a link on Page 1 to an example)
2. Go yarding for one or check Car-Part.com--Used Auto Parts Market
3. Someone on here may have a spare
4. If you let us know what year and engine we can see if there are any available New Old Stock (NOS).

.

 

What engine? I've got a few FE fans laying around...

 

I am saying that pulling a hill at 50 mph you WILL NOT Get any more air through the grill and radiator.

So by the time you pulled off the shoulder back on to the road after installing the fan and shroud, things had changed.
