I've been digging through a few threads regarding the Grand Cherokee E-Fan's. If I understand everything correctly then they're literally plug-&-play for those of us with 2000+ Dak's and OEM E-Fans? Just need to have SCT to modify the temp in which the fan kicks on? (180)

Also, was there ever an official answer for how much air the GC fans move? I've seen 4000 cfm mentioned a couple of times.

4000cfm plug and play on 00+

01+ are the only ones that can control fan speed (what I was told by Sean)

Exactly what I wanted to hear. Thanks User!

What year GC fan should I be searching for?

I did a check online today actually using s PN I found in a post and it seems to be the correct one.

Grand Cherokee electric fan PN: CBG4F250

Dealership should have them for around $50 or so, online they are around 86+

To clarify this for me, If I put a GC fan in my truck and eliminate the mecahnical fan, he can turn on the GC fan at any temp and turn it on when I turn the AC on? I could run just the GC fan and eliminate both my mechanical fan and the stock electric fan on my '03? Sorry if this is a dumb question. ha. Id like to get rid of the mechanical fan but I dont want to have to worry about any overheating issues. Thanks

Not all of them, because my 00 was not able to do it.

Also 195 is the normal temp the fan kicks on. So he didn't change anything, he normally turns it on around 180-185...

Bringing this back from the dead. What are the popular mounting options for the GC fan.

I saw this thread - http://www.dakotart.com/forum/showthread.php?t=7847

It doesn't mention where he got the shroud though, is it required? Does anyone know if it's possible to use the stock 01+ fan shroud with the GC fan? I'd like to keep it as it has the coolant overflow and washer fluid bottles integrated.

you'll need a shroud. i ran the fan till it got about 100 degrees then the truck started over heating cause i didn't shroud it. i currently made one out of aluminum but it's kind of an eye sore. so if you want to shroud it and mount it at the same time CHRIS AT PIE is shipping me his custom shroud that he made for our truck that is specifically for the gc fan. the fan mounts to the shroud supposively. $150 + shipping though. but its a good looking piece. call he and check it out

I have the GC fan for some time now and it works flawlessly......even in the hot FL summer heat. I don't have any additional shroud, just the fan as it is.

Mine is fully plug-n-play on my 2000. The simplest mod you will ever install.

Same here, I installed mine with a new waterpump and a 160 thermostat, when it was 115-118 out, even with out the flap seal the temp needle has never touched half way. Although i will probably have to switch back to the 180 thermo when it gets cooler out. great plug and play (2001) addition for sure :biggthumpup:

Looks like a sweet set up. However for the 01+ models it looks like we'll have to figure something out for the coolant overflow and washer bottle. The factory shroud has them built in.

Some people use the JAZ cans for the overflow and a washer reservoir from a 99. I never installed my 99 washer reservoir because it's garaged. I used a overflow bottle from a 94 Ram on mine. I made a simple bracket and mounted it using the existing bolts on the side of the radiator. Nothing fancy, but effective.:r/t smile:

Here is mine. Jaz bottle bolted to where the 2k up shroud reservoir combo used to go. I used a 99 washer fluid reservoir. Bolted right up to my 2000. Ignore the MSD box wires stretched across, it was ugly I know.

I kept it recirculating, the stock tube from radiator hose goes to bottom of tank, the one on top is the overflow tube.

No, even if you have Robs mounts the shroud would not be held on. He told me he designed it to get rid of those mounts.

There are several "L" brackets included with the shroud. However, they aren't mounted on the shroud anywhere. It looks like I'll need to come up with a way of mounting these tabs to the shroud. Probably going to have to pay someone to weld them.

I thought about that but judging from the pictures above. The "L" brackets are positioned on the shroud in such a way that they are sandwiched between the radiator and shroud. There would be no room for a bolt head or nut.

Granted that's just how I'm see it in the picture. I'll have to play with it more once I get home.

because of the design of the fan, you can't really use it without a shroud. it will not fit flush to the core like most electric fans. both sides of the fan have a taper to them, so you need a shroud to mount the fan to and to seal the fan to the radiator.

and yes, any fan SHOULD have a shroud, so that you move air through as much of the core as possible, vs only the fan diameter.

I'm trying to remember the conversation I had with Chris when I ordered my shroud. I BELIEVE he said that the testing he did with the shroud would yield around a 20 degree drop in the engine bay.

It's a nice piece. Just requires a little bit of fab to get it to fit your application. It does it's job.

I've never ran a shroud on any of my setups and have never had issues. Hell the 2000 used the stock efan with no shroud and ran fine, although I did have a 180 thermo, distilled water, high flow water pump and water wetter.

I'm running the GCfan on the 01 now with no shroud and it's doing perfectly fine. It was 97 (102 index) this weekend when I drove it around, and that's in DFW's stop and go traffic.

whats the clearance looking like on this shroud? like between it and the crank pulley? i ask because i may change my black magic fan out for one of these and wire the fan to a manual switch since mine is a 99, but i need enough clearance for my paxton pulley as well. my temps stay down well with steady cruising and mild stop and go, but will creep up in heavy traffic. the black magic fan shroud doesnt cover the whole radiator unfortunately.

So earlier then 2000 you pretty much have to wire up to a switch or temp sensor of sorts correct?

Got mine installed today with a new radiator. Didn't get a chance to drive it in 100º plus weather yet. Install was easy. Drilled and cut brackets to mount to radiator. I did not take any progress pics as I was working. Sorry. I can get some installed pics if anyone would like.

Ok there must r a different part number cause I called both Canadian an us dealers and that number is over 250 bucks. Where's this 55 dollars coming from ?

All the dealerships I checked wanted a stupid amount of money for the fan as well. I ended up buying it from Summit. $77.

I put the GC e-fan on my truck and sitting still idling in 100* weather it didn't get above 165* or so after idling and a 10 minute drive. With the stock e-fan it would have reached 200+ degrees for sure. FYI I'm using Rob's brackets...no shroud...seems to work great! Better than I anticipated!

That reminds me that I still need to ship your flap seal.

Well, the temp was 106º on my 15 mile drive home from work. Combination of highway and stop and go and here is where my temp gauge stayed for the majority of the trip. Its still a lot warmer than what I would like it to be. I have a 180º t-stat and when its below 100 it will sit just above the first hash mark on the gauge.

That's pretty good, by my gauge thats the 210 mark in the middle and I ride just at or a tic over it with my PIE GC Fan and 180*stat with water wetter,:idunno:thats in mid 80's temps here with A/C on and stop and go it only tips 210 at a light sitting.Hit the gas and get cruis'n it's 180's:biggthumpup:

I know its not overheating or anywhere close to it, I just think it should be running cooler than that with the 180 t-stat. I'm worried that when I tow my camper up north in these hot temps that its going to overheat.

Your SCT tune should be set to turn on the fan @ 185* so your not going to see 180 temps that often. I'd say the truck stock ran 210-220 easily in those temp's so your good to go:biggthumpup: I'm guessing your going to be fine towing that camper as long as you have a good trans cooler ran into the factory cooler correctly.

The wet water work's I saw lower temps with it also it helps to use more water in your coolant mix and as long as winter temp's stay above freezing you can do that.

I've got about a 70/30 mix of water/coolant, and my sct is set for 185º. I do not have an auxillary trans cooler though and I've been wanting to get one. Do you think that will help with my coolant temps a little bit? How about a small pusher fan to mount on the front of the condenser to help out when I'm pulling hills?

A good trans cooler will help some, if you have a stall converter it's a must to keep your trans alive. What size radiator did you add? A stocker or did you go bigger? A pusher fan might help, then again it may block flow thru the rad when its off?

azdurango
07-30-2013, 03:54 AM
No stall converter installed. I bought a stock radiator but it was only 1 1/4" and the one I took out was 1 1/5". The new one was labeled as the max cooling radiator so I'm not sure. Would love to get the bigger radiator from wizard but 800 is a little more than I want to spend.

I don't know if I'm sold on this or not. Today on my way home from work on the highway the needle was right at the halfway mark and on the streets in stop and go it was just above half way. Ambient temp in overhead was reading 111º.

Do the 4.7s run hotter than the 5.9s? With my GC fan without a shroud, it has never gotten that hot, even going up long passes in the desert on the way to phoenix :idunno:

I don't know? I don't see why it would run any hotter. I have a 180 t-stat in there and stock is 195 just as the 5.9 I believe. How hot does your 5.9 run without the shroud? Stock radiator? Stock t-stat?

Stock radiator, 180 t-stat. This is where my gauge always sits:

It goes a bit further if its a really hot day, 110+, but I've never seen the needle reach vertical or past it.

I was really hoping that this would be the hot ticket to keep my temps where I want them. It's weird because I can feel that my ac is colder but I can barely feel any air being pulled across the radiator when I stick my hand up to it. Maybe I need to crack open the wallet and get the big wizard radiator and a viper e-fan. Damn truck is starting to piss me off. :fml:

This is with the GC fan and shroud? I can feel air being pulled about a foot away from the radiator. Bryan posted a video of his installed and it was a pretty good demonstration of how powerful it is. Have you seen actual temp readings? And not just what the needle is showing?

I can place a piece of paper by the radiator and it will pull it up but it just doesn't seem as much as I thought it would be. Also I have not seen actual numbers. I am probably going to hook a regular temp gauge too so I can see where it actually is.

Very much so, the shroud made a huge difference. It went
in easy the fan bolted directly to it with very little grinding
on the molded brackets of the fan. It's a very nice piece
it puts a nice finish to the engine bay. Thanks for getting out
To me quick.

I am extremely pleased to say that I have figured out my problem. Do Not use an aftermarket fan. I picked up an actual mopar fan out of a GC on craigslist and I've been driving around all afternoon in 105º weather and this is where the gauge sat most of the time. Never even got close to the half way mark.

I've upgraded to an efan and struggled trying to figure out what makes it blow. I figure this is as good a thread as any to post this information. Some have posted bits and pieces on what they know or what they think they've seen, but this is the information directly copied from the 2002 Dodge Dakota Service Manual:


What conditions cause the efan to blow?



7-53
Pg 276

The electric radiator cooling fan is controlled by the Powertrain Control Module (PCM) through the radiator cooling fan relay. The PCM will activate the relay after receiving inputs from the engine coolant temperature sensor and/or an air conditioning on/off
signal.
Not Equipped With A/C: The relay is energized when coolant temperature is above approximately 103°C (217°F). It will then de-energize when coolant temperature drops to approximately 98°C (208°F).
Equipped With A/C: In addition to using coolant temperatures to control cooling fan operation, the cooling fan will also be engaged when the air conditioning system has been activated. Refer to 24 - HEATING & AIR CONDITIONING for additional information.


In other words when taken literally, what this means is that the operation exists identically between AC and non-AC trucks EXCEPT that AC-enabled trucks will also engage their efan when the AC is on.

BUT having worked for AT&T I know that internal documentation can often be inaccurate and conflict with other documentation or simply be gawd awful. So I found this additional information:



7-62
Pg. 285
Radiator fan – Electric
The electric radiator cooling fan is controlled by the Powertrain Control Module (PCM) through the
radiator cooling fan relay. The PCM regulates fan operation based on input from the engine coolant
temperature sensor, battery temperature sensor,air conditioning select switch and vehicle speed.

The fan is not energized during engine cranking regardless of the electrical input from the temperature
sensors and ,air conditioning switch. However, if engine operation conditions warrant fan engagement,
the fan will run once engine starts.

On vehicles NOT equipped with AC: The relay is energized when the coolant temperature is above 80° C (176° F), or battery temperature sensor above – 12° C (10° F). It will then de-energize when coolant temperature drops below 82° C (180° F), or battery temperature sensor below – 9° C ( 16° F).

Vehicles Equipped with AC: In addition to using coolant temperature and battery temperature sensor to control cooling fan operation, the cooling fan will also be engaged when the ,air conditioning system is activated. The relay is also energized when, air conditioning is selected and coolant temperature is above 95° C ( 203° F), or , air conditioning is selected and battery temperature sensor is above 41° C (106° F). It will then de-energize when , air conditioning is selected and coolant temperature is below 92° C (198° F), or , air conditioning is selected and battery temperature is below 38° C (100° F).

In the above info I believe there is inaccurate information in the "NOT equipped with AC" section because it would mean that the efan is engaged whenever the battery temp sensor reads more than 10º F.

In the "Equipped with AC" section it describes something similar to the other quoted text but lists two scenerios that activate the relay and both require the AC to be selected. Also, the section initially describes that vehicle speed plays a role but it is not mentioned any further.

What I need to do is look at the wiring docs to see what exactly happens but I spent so much time dealing with internet bullshit caused by Comcast that I didn't have the time.


So I'm still not sure if my efan will kick on without the AC being selected but what I do know is that we've had nearly 90º weather for the past few days and my temp needle gets a little past halfway and won't go up further. That's safe, but prior to the efan it sat no further than halfway and I have never seen it active without the AC being on.

04-11-2015, 11:44 PM
The fan will not turn on if above 35-40mph(not sure on exact speed) even if A/C is turned on, unless the engine temps get too high. Which would be 217 according to the first part. I think the 176 degree on and 180 degree off numbers in second part are wrong, as well as the battery temp since both sets of numbers contradict each other.

What are those of you doing with the fans before they were plug and play? Just installing the fan and using a stand alone controller I'm assuming? I'm going to ditch that clutch fan in mine.
