no, I just did the same trip, 300 miles in two
days, 90+ degree weather. mostly highway, if
you have the 180 stat installed, you shouldnt
have anything to worry about.

I know I have asked this before... You guys are saying basically you can take your clutch fan off and run just the electric one with no problems. Does you electric one run more often now, or about the same as it does with the clutch fan. I am in WA. State so it does not get real hot here anyways, but just double checking before I heat up my motor. Thanks Alot

The electric fan automatically kicks in when the coolant temp reaches 210 degrees (the PCM makes it come on). It also runs everytime the A/C compressor comes on. I've had mine off for 6 months. Even in Atlanta heat (it's been 97 degrees the past coupla days) it still runs cool with the A/C on. You really need to have the 180 degree thermostat installed if you want to remove the clutch fan, though.....
Just for reference, if your vehicle is moving at 35 mph or more, you really don't need any form of radiator fan...... On highway trips, you'd pretty much have to be driving thru Death Valley towing a house in August before you'd need to worry about cooling....... (if you've got the 180 t-stat).

I took mine off about a month ago. I noticed right away that the engine seemed to rev easier, got up thru the RPM's quicker.
I was a little paranoid about overheating so I carried it in my truck for a couple weeks.
I've sat in traffic with the A/C on when the temp was nearly 100 and not even a hint that it was going to overheat, and I'm running the stock t-stat. IMO the factory elec fan is more than adequate to handle the cooling duties and the clutch fan is overkill (and POWER-KILL!!) Take it off & enjoy....

As Alex has stated your truck or any other vehichle does not need the clutch fan when driving at speed.

Im wondering if any of you that have taken off the clutch fan have 4x4's? If you do and plan on 4wheeling then the electric is not enough!! The first time you drive in sand or try to climb that steep hill in 4-lo you are gonna heat up. I have experienced this in my 97 dakota 5.2 with the clutch fan removed and a Black magic 150 in its place and also in my girlfriends 2000 durango 4.7 with a bad clutch in the fan (basicly running only on the electric). I am wodering if there really is an electric setup that can TOTALLY cool our v8's in every situation. If there is.... I want to know about it!!

you can get a switch and turn the elec fan on
manually, the stock elec fan on these trucks is
pretty big, it should be able to cool down the
truck under almost any condition. I wouldnt
worry about it unless you were running forced
inuction, turbo, or s-charger, where the heat
factor is increased.
