Running without a fan??

[ScottyP5947]

Ok so I just heard that the local Ford dealer's diesel mechanic has a 7.3 and drives it without a cooling fan. I have only found one other post on the subject anywhere. Supposedly he has no issues at all. He's never overheated, ever. Can't imagine he tows a lot with it like that. Anybody else run with no fan?!?

Never heard of that. I pull a 12K 5th wheel. I don't think I'd even try that.

I'll tell you this i've only had my fan come on a handful of times, and once it ran constantly when i was towing my horse trailer in over 100+ degree weather... but honestly it rarely kicks on it has to be pretty hot out to even think about it. That being said I definitely wouldnt do it towing heavy..

You have an electric fan setup? What temp is it set to go on? I don't tow at all over winter. That's an amazing cooling system if it functions that well without a fan.

I haven't had my fan on for the last 3 months. (My fan clutch wobbled and was working on taking out the water pump)

I haven't been in a hurry to replace the clutch because it doesnt run any hotter without the fan. If you're not hauling heavy or crawling around at very slow speed all the time you'll be fine.

The cooling systems on these trucks are extremely efficient for sure. And remember they run hot. And if i was in a mild environment and didnt tow i may think about it. but its nice to have it come on when it needs to, thats for sure.

Or you guys could try this mod. I have been wanting to get an on/off style fan clutch for some time. Here it is!

Just bought my replacement water pump from Napa - I'm going to run without the fan for a bit while I have it off. More MPG to counteract the winter fuel and low temps outside.

First time I ever heard of anyone running without a fan on these trucks.

No doubt. I was shocked when I was told too. The strangest part is that it's the Ford diesel tech from the local dealer who has been doing it 'forever'.

It's definitely something I would have NEVER tried without all the other testimonials. I still think it would make me uncomfortable in the summer...
