Electric Cooling Fans:
Pro's
More HP from your engine.
Can turn off for water crossings.
Might be quieter than stock fan.

Con's
Needs electricity to run. (Bad alternator or bad battery = potential overheating, warped heads, long walk home thru the scary woods at night)
Engine driven fan is always available.
If it is hooked up now it is FREE!

I have electric Fans! They are noisy but they cool just as good as the clutch fan and it's easy to tell if they are woring right compaired to a clutch fan. They also make it allot easier to work on anything else under the hood as they free up space.

Hmmm, hard to tell. I never new when the clutch fan was going in and out but it feels like the electric fans pull more air. I have the Flexilite 210s I think.

cool was installation pretty straight foreward? this seems to be a good idea for the D-90 easy way to pick up a few HP and keep it cooler? I have only seen one of these and that was on a 2.5 diesal.

Hardest part is getting the old fan off. You need a big wrench or a strap wrench to hold the pully in place when you try to unbolt the BIG nut on the clutch fan. Putting on the new fan and wiring it is easy.

The 210 comes with controls, the 220 without. Not exactly sure if you need the controls. I do know you'd still need to buy a override switch if you wanted that (and you do) for the 210...

I am contemplating this mod too, but as always the price is just enough to make you go mmh.

Other advantage is that the electrics blow air even when you are running at low rpm off road, rock climbing, etc. I have the 210 Flexalites with the controls -- I have them set to come on at 180 degrees. I have a mechanical aftermarket temp gauge plugged into the hot side of the radiator so I can see what's going on, and the engine has a 160 degree thermostat now. My AC fans come on at about 220 degrees without the AC running (with AC on, they run all the time). 220 is kinda warm and I'd like to figure out how to get those ac fans to kick in at about 200 instead. (Remember I have unusual cooling issues 'cause of the engine.) Doubt there is a way to change that, but open to ideas...

Ok, but what I want to clear up is if I need the "controls". The plan is to buy the flexalite 210/220, the vw fan switch (Beck/Arnley 201-0809), and a switch to override it.

So would I need the controls? Aren't the switches all the control I need?

Sorry for the questions - I'm just a CB and can save I can save $25 if I get the 220. Thanks,

charles

Charles, You don't need the controls, you can use 2 30 amp relays instead, thats what I use, they are cheaper and easier to replace. You just use the VW switch to turn on the relays. I have each fan run on it's own relay and fuse, so if one fan dies it does not take out the other. I can post a wireing diagram I have at work on Monday.

Doug why not replace the AC T-stat switch with the VW one that Charles is using? I am sure they sell different switches that turn on at different temps. I bet they have one that comes on at 195*.

Thanks Mike. Please send the diagram.

I'm making one last attempt at trying to find a (cheap) US counterpart to the fan clutch, and If I can't pull that off, I'm getting a flexalite 220!

Doug, from the reading I have done, you don't need the switch for the AC, even if you use it. Just hard wire the AC fan to come on all the time when you are running the AC (ie bypass the switch) and use the switch location for the flex.

Something I found out at MAR is turn the AC to hot and the fan will come on with out turning on the compressor. Had hot running issues at MAR. Charles let me know if you need a hand with the install. As I'm headed that route soon too.

Actually the best is to just unplug the lead to the compressor and run the ac. Works for me

Hey Tyler - just noticed your edit. I'll let you know if I go that route. Not to jynx myself, but it sounds like the hardest part is removing the old fan.

Hi Vadim

Now were talking! Although around here, we can't go into the junkyards - they only let you buy the stuff they pull.

So... Do you happen to know what year eagle? Roughly what did they charge you? Specs on the relay too if you have them

Also, regarding switches, I'l like to put a "stock looking" switch inside. I have something that looks like a dummy switch for a rear defroster or something that i could replace. Anyone know where I can get something like that?

Thanks
charles
