Mechanical Fan to Electric Fan 2003

[Vtolds]

Has anyone changed there Mechanical fan on the 3.7 liter motor to a Electric fan? I have heard you can gain some hp, performance, and fuel mileage by doing this.

Don't you have the electric fan in addition to the mechanical fan. Ie, if you go to the HD cooling and they add the mechanical, don't they leave the electric fan present?

 

[Vtolds]

You are correct sir. I never really stuck my head in there to have a real good look under the shroud. So is there a way of dropping the mechanical fan, or is that not possible? +While I was in there I noticed I really need a new belt, so I think that will have to come first.

I have both on mine.

I wish I had both. The few hp loss is worth the extra cooling and peace of mind in the summer heat.

In theory you don't need the mechanical clutch fan on the front of your engine if you're not towing anything. But removing it will only improve you mileage & performance by a small amount.

Before you do though make sure your electric fan is actually working otherwise you'll have overheating issues.

anybody had any problems with running just the e-fan with the towing package? thinking about doing it to mine since i dont haul anything and would prefer small amount of power and mpgs it would add.

anybody tried towing or offroading with just the e-fan?

I haven't towed anything with my Liberty yet, but I go offroad all the time with just the e-fan. Never had any overheating issues.

We just recently added the heavy duty mechanical clutch fan to our Rig.
And not for towing, but rather for keeping the ****** temperature down
when in the back country when we're fully loaded with camping equipment,
recovery gear, extra fuel, food, etc.
We've gotten into some really long steep accents at higher elevations and
had transmission overheating problems.
We now also have the in rad ****** cooler as well as the original stand alone
transmission cooler.

Does any one know the correct air flow direction on an electric radiator fan.
Thanks

Clean air in through the front of the radiator and in to the engine bay. ????????
