Permanent removal of engine fan? Driving without fan

So as I'm rebuilding the injection pump etc etc I'm wondering..... is there a real reason to have the mechanical clutch on in mild pacific northwest weather? Don't these things have huge radiators anyways?

Long story short considering leaving it off. Anyone done the same? Any reason why i shouldn't?


My 4bt and 6bt cummins powered ford neither have fans. Never any overheat issues. I understand its a v8 and not an inline and that makes a big difference in heat shedding.

What could you possibly gain?

Mine will get hot towing on a couple mile long incline.

It has a clutch, is your bad?

Doesnt feel to be bad. Just didnt know if there was a purpose or if it was simply put on for backup in desert driving etc

If you idle for a while in the summer on a hot day I think it could be an issue. My 7.3 in my F350 has a bad fan clutch and won't engage at idle. It has started to overheat if it idles for 15 or so mins on a hot summer day. Or a lot of low RPM low speed crawling.

Dude your 6.2 motor is an IDI diesel.. they make twice the than that of your cummins. also it is automatic tranny that is smoking hot when the truck is run at 2600 rpm ect..

Very true. So it needs a new fan one way or another it seems.
