Engine Fan

My 05 has 2 engine fans, an electric fan mounted on the radiator, and an engine driven fan

I dont know if all libertys have both, or just the ones with the tow package.

anyway, I was wondering if the electric fan cuts on by temp or if it comes on with the A/C and defrost. My point is, if it comes on by temp, Im going to drop the engine driven fan for obvious hp and mpg gains.

My 2002 4x4 Sport does not have an engine driven fan. My electric fan is turned on by the thermostat. I run fine without an engine fan and I have towed a 8000 pound 3/4 ton 6.5 liter diesel Chevy Suburban 4x4 at speeds of up to 50 miles per hour. I am not making any suggestions here but you may be safe without it...

wow, how the heck you towed that i will never know. Hey KJRenny, if you do take that off and want to sell it, send me a pm. Im not sure on how it mounts of if i would need a new pully. As long as you send all the bolts and the clutch with it. Throw me a price if you want to sell it.

Only those that came with the tow package got both the Viscus (engine driven) fan and the electric.....the rest w/o only got the electric. On mine, since I don't have the tow package, my elec. fan kicks on when it gets to a certain temp, I turn the A/C or Defroster on....and first thing in the morning when I first fire it up.

Yea, I'm trying to pull off my engine driven fan, but no parts stores have the wrench set that takes it off... they only have "universal" kits which wont work, so I will be makking a set of wrenches tomorrow out of some old craftsmen wrenches.

I have to free up a few HP, my new 245/75 tires are dragging down my poor engine on backroads and highways.

One correction. My 2005 Rennie has that fan, and I did not get the Tow Package, instead I have the Off-Road Package that also comes with the Heavy Duty Engine Cooling (w/ the engine driven fan).

If you wheel I'd keep it! Your radiator has a tranny cooler built into it as well and the electric fan doesn't kick in when the transmission gets hot. Not to mention that the electric fan has a tendency to give up the ghost after water crossings.

I removed the fan and have felt no power gain and have seen absolutly no change in fuel economy.
