Damn Indy where were you with this info before I did my fan replacement. I'll have to look into this to get rid of the parasitic draw for cheap. [8D]

That, or you can go to a salvage yard, and pull one off of a Lincoln Contintental... as long as it has the 3.8L engine, and an e-fan with three wires, you got the fan that has a low setting of 2500cfpm and a high speed of over 5000cfpm...

I got mine for 20 bucks.

Works PERFECTLY!

I got mine off, I believe like a 93 Continental...

Seriously, takes a 7/16 socket to take it off, two bolts at the top, cut the three wires as CLOSE TO the little module box you can... then look for rtkota5.9 or whatever's little relay diagram and do it that way...

I'll have a how-to up....

Eventually.

Indy,

is this the fan you are talking about?

http://search.ebay.com/search/search...&category0=

These markVIII fans sell for $45 on ebay. Could you give some deatails on hooking it up? I am completely lost on how I would do it with out instructions. Will I need to Mod anything?

And Most importantly, do you do any towing?

Thanks!

ORIGINAL: Dman98

I did the viper fan upgrade and have no cooling problems. The viper fan is a two speed fan, in my installation I only use the low speed and the high is wired for emergency use via a cabin mounted toggle switch. I used the fan with the a/c on in 95 degree weather, with no problems at all and idling the temp stayed at 188. I upgraded to a 165 amp alternator, the optima yellow top the largest that would fit and this was done because of my stereo system. I don't tow, if I did I'd use the same or use the high speed only which ever works best.
How are ya'll checking your temp this accurately?

For that price, it's hard to pass up. I may get one to try. Then we can actually answer everyone's question if the E-fan can actually replace the clutch fan when the D is used for moderate to heavy towing.

Just odd that I had yet to see any trucks out there that has a electric fan only setup? I wonder why the factory does not want to choose a E-fan over a clutch fan on trucks. Saves gas and reserves more power for get go! Maybe the clutch fan is cheaper and more reliable in the long run?

Well I just went to the pick-n-pull and picked one up so I gotta get all the wirinig and relays and I'll get this sucker in. I was talking to some guys at the yard and they said they did the same thing with their project 5.0 and the guy at the register said he'd used them before. Another weird thing is he said his 04' was running an e-fan only on the 5.2 and that it came stock, never heard of that on the Dak...

They had quite a few cars to choose from too. I actually got mine out of a mercury with the 3.8 so I'm guessing any early 90's 3.8'swill do.

Here's a diagram I pulled off of DT

Interesting wiring, Looks like they are missing the A/C wiring piece of it to make it all work together! Unless you get to keep the OEM Efan!
