I used one from jegs..give me a few mins and I will get a link...The one i have is adjustable, and kinda like this setup so if im at the truck or going on the dyno I can turn my temp down if I want

Cool, thanks, does anyone know at what temp does or t-stat open at? I will go from there and try and get a fixed on/off temp sender installed. Is there any free coolant plugs in our manifold to install the temp sender or do I need to start looking for a alternate location to mount sender. Thanks for the help. Tim

 

Im thinking the stock is 210* but im not 100% sure, alot of guys are running a 180* stat now.there are coolant drain plugs on the block right above the oil pan drain, not sure if I would use that or not though. I remember seeing plugs somewhere else when I was pulling my engine apart last week, but cant remember where. If I didnt have a cast on my ankle I would walk outside and look, ha ha

when the fan blades are off the viscous clutch
it will consume nearly no hp...perhaps 0.1

when considering installing an electric fan for fuel economy improvement
keep in mind that the air pulled through the radiator
is a worse MPG decreaser
than the hp consumed by the fan itself.

you will get the best MPG improvement
with no fan running (either electric or mechanical)
and with the minimum airflow through the radiator
that will keep the coolant at your desired temperature

these are tricky points
...the running fan either pulls hp from the engine shaft or the alternator
...the air flowing through the radiator and exhausting underneath creates drag that the engine has to overcome with more hp to the drive axles

for more info do a search on Chrysler's
"Magic" and "Apollo" projects
to boost the MPG of the 4.7 v8 and the Durango

 

I have personally been running without the clutch fan for well over 4 years now. No issues what so ever to date with charging OR HP. Gains where a solid 10RWHP on the Dyno and that seems to be a consistent number from other forum members who have had them DYNOed after installing an electric fan. Also removing the clutch fan equated to 2-3MPG gain, It was significant and noticeable even without doing the math... It added just under 2 days of driving to the tank. I had a normal fill up day (Thursdays) and the fan extended it to the weekend.

Our fan blades on our 3rd Gen Rams do NOT come off the clutch as they are "RIVETED" to the clutch.... It would be 2000x easier to just remove the fan from the pulley which is held in place by ONE large lug. If your worried about overheating then toss the fan in the back of the truck, if your overheating then "SPIN" the fan back on and hit the road. No tools necessary to re-install the fan, it spins off an on... getting it off can be a PITA but re-installing it takes no more then 20 seconds.

The E-fan is a great mod and is one EVERYONE who is looking for increased performance & fuel economey should look into. If your a "fan" of the factory clutch fan and feel it is more efficient to run one, you obviously have NOT done your own real world testing, its your loss. Fact is, the factory clutch fan takes approximately 10RWHP to operate when NOT engaged. These numbers have been posted by not just my self but from many other people who have done this mod.
