6.0 isn't as tough as a 7.3.
If you take care of your 7.3, she shouldn't EVER overheat.
I've never seen too many 6.0 electric fan clutches having issues cooling, but I've heard grumblings about low speed/idle cooling.

I would only recommend for a 6.0 what I stated earlier. Heater bypass and if that doesn't help enough, add a fan.

Testing?

On the dyno, there was 10hp loss between a new and old stock style fan and clutch. Without a fan, I picked up almost 20hp.

Temps without a fan?

Max was sitting for 14 minutes in traffic. I hit 230*. Stock gauge hardly hit mid way. Aftermarket gauge stated 230*.

Have I pulled without a fan?

Yes. Dual axle car hauler with a f150 on it. No issues.

If you are pulling 15-20k with your truck, I wouldn't recommend it. And regardless if you keep the stock fan, remove it, or add secondary fan, always test and monitor your truck.

How hot is it where you live, I'm in Miami and have never heard of a car without a fan.
