I've sold hunreds of the Flex a Lite electric fan kits for the Hemi Rams. We dynoed 8hp and 11tq on an '03 Hemi Ram.

I had the same fan on my truck for years before I sold it (now I have an '09 Challenger R/T).

You can either install the fan inside the 'stock fan shroud' or delete the stock fan shroud with the kit I make and sell.

I like the 180 degree thermostat to go with it, they work well together.

Please post more questions on this if you think of anything.

Here is the link to the fan shroud delete kit. You can customize it by adding the Flex a lite fan and thermostat for a discounted price.

I was thinking of doing that as well but i rather put the $500 toward some headers or someth8ing else that will notice the power. I dont know what youve done but maybe doin electric fan last would be a better idea

 

Scatpak07, the 180 fan is only $259.99 on my site by itself. It's hard to beat the 'bang for the buck' for the fan.
The power you get is at all rpms. I got approx .3 at the track gain just from the electric fan.

You do make a good point about exhaust though. Our hemis are really choked.
The stock manifolds are really small and where the stock tubing from the 04+ Rams meet at the Y is really smashed.

 

Oh thats not that bad I was looking at fans and they were like $500 so I was mislead haha. I was told by my good friend that electric fans are a better addition down the road when lots of upgrades are done. Moire of a finishing touch kinda item. But I believe you when you say its good im not going to go against you on that haha. Well I might have to look into one for myself then

 

Flex-a-lites are the way to go .

 

I ordered the flex-a-lite fan and fan-shroud delete kit from Moe's. When I do my rad flush next month it's all going on then. I'm doing it as the prelude to the engine work that's to follow to clean up the engine bay.

 

Can i keep my shroud with a Flex-o-lite or do i have to go with the overflow bottles they offer?

 

I have been looking into an electric fan also. Do you have kits for an '02 4.7L engine?

 

F.Y.I. please guys save your self alot of money....all you need is a electric fan from a 2000 grand cherokee 4.0 $25.00 at local junk yard it will fit your hemi fan shroud...if you look at the shroud on the edge it has mounts for an electric fan already there.. if your not comfortable with the used electric motor a replacement motor is around 65.00 bucks at the auto parts store...u can get a pre set or ajustable temp sender and relay there too...it is called electric fan install kit its like 30.00 bucks you can also use a 96 taurus 3.0 fan too...they both pull enough cfm to cool that hemi down......its been on my truck for the last 2yrs with no problems yet .........

Wowo- That is great information- does anyone know if this will fit a 2010 Ram 1500 (5.7 L). If so how is the operation controlled- temperature sensor turns it on? what turns it off? Sounds like a great mod to gain some free HP.

 

Wow, That actually works! Im going to go to pull-a-part and looking tomorrow.

 

Heh Moe, can I keep my shroud in my 09 Hemi with the flex-a-lite? Do I just mount it closer to the rad? How much is the shipping to Hawaii? Send me some info please. Mahalo and Aloha. If I can buy it cheaper from you than in Hawaii I will.

 

Well I didn't get an answer from Moe's but, I did get one from Flex-a-lite. 03-08 is supposed to fit my 09. At 3300cfm's it should be enough to be my primary fan. The Kit # is 183 and runs around 3-4 hundred.

 

Sweet, so when you do it are you going to keep the shroud or do the delete kit?

- Cajun epper:

 

I wonder if would make a difference on a diesel?

 

Can someone give me step by step instructions on how to do the cherokee e fan install on my 06 ram??

 

replace engine fan

I used a replacement part from my mustang cobra. spal makes it and it was $139 dual speed fan. it fit the radiator very well without removing the shroud. $65 therm dual temp control.
I wired the low temp (180) output to the low speed fan input and higher temp (210) output to the high speed fan input.

This fan is the same fan that cools my Cobra's 409RWHP DOHC 32V motor

works very well. the engine seems more responsive to throttle input off idle.
I get a little better MPG as well, maybe 1 or 2.

 

I forgot to mention, you will also eliminate the start up whine from the stock belt driven fan.

 

Hey make sure you measure the deminsions of your radiator before you buy a flex-a-lite fan kit or any fan kit for that matter fitment is key. The 03-08 part #264 is too tall to fit the 2009 radiators if you dont think so just go measure it your self.

 

I looked at the Flexalite #183 kit and it seems a bit small to me but hey if it fits which it will and does the job then hey can't complain. I just think a duel fan might be a better application for trucks cause i had one on my 02 Sierra. Im pretty sure with this kit you will have gaps.

 

I wonder how many 4th Gen folks contemplating removal of their OEM fan system will 'scratch their head' when they find out that they already have an electric fan,,,

Yep, mounted against the radiator in front of the clutch fan,,,,

I live in Houston, and even on the hottest days, the thermal clutch hasn't engaged nor has the temp ever risen past ~206-207~ with the 203 OEM stat,,,

Perhaps 3rd Gens would benefit more as they have 100% clutch fan cooling,,,

 

So your saying I can take off my clutch fan and my truck won't overheat plus gain power from not having that parasitic draw

 

Not exactly,,,

On 4th Gens,You'll notice the e-fan comes on everytime you turn your A/C on. Hot, cold, whatever,,,, keeps air moving over the condenser and the A/C works better.

As it does not turn off exactly at the moment the A/C is switched off, I cannot confirm or deny that the E-fan may also be temp regulated,,, Again,,:4-dontknow:

In the summer when its hot, my A/C and my e-fan run constantly. I drive pretty conservatively, Houston is pretty level, and I don't tow or haul,,,

In my case, even in stop and go traffic, the E-fan seems to move enough air to keep from running hot or from having the thermal clutch engage.

(FWIW, the 3.7's have electric only cooling, and their fans look virtually identical to the ones the 4.7 / 5.7 have strapped to the rad in front of the thermal clutch)

Now, in stop and go traffic,,, If I were to tow, drive aggressively, run up steep grades, etc,,, the E-fan may not be enough,,, and the clutch fan is there to assist. (Still don't know if the E-fan is linked to temp for sure)

The clutch fan itself, if memory serves me, is only a 'rather modest' nylon/plastic 5 blade,,, not a real 'air mover' when compared to the 9 blade "20 lb" OEM metal fan I had back on my 455 Firebird,,,

So,,, How much parasitic loss does one get from a 'typically disengaged' lightweight 5 blade fan? :4-dontknow:

Even when disengaged, it does pull a little air at the stoplights, which isn't a bad thing,,,

If one wants to go full electric, I understand, but in my situation, with the cost of parts and my time to install, I just am not convinced that the difference in fuel economy would ever justify the expense.

I don't race, so a quicker rev'ing engine (less mass to spool up) wouldn't matter...

As always, Your mileage may vary!

 

Well i did start scratching my head a few months ago when i saw that e-fan. But apparently its not made to cool the radiator its made for more or less the trans cooler. Correct me if im wrong but this is what has been explained to me by the techs we have here on the forum. It has been advised to me to not remove the stock engine fan even if you have a 180 stat. Heat will build if you are at idle or in stop and go traffic as the fan is not enough to deal with the heat.

 

it might work if you can find a way to keep it always on to a certain degree...my brother has the same thing on his dak..in front of the clutch fan was an efan on the radiator...he wired it to a manual switch and to an efan controller so that he could turn it on high whenever he wanted to or let the controller turn it on and ramp up depending on need..

 

Well my trinity lets me control the temp at which the e-fan kicks on. Also it lets me control the e-fan even when my A/C is off. This is why i originally thought i could run the whole system off it. I have it set for 180 for both A/C on and off. I notice that it stays on for a few seconds after the engine has been shut off.

 

Have you ran into any situations yet where the Trinity-activated OEM E-fan wasn't enough?
