LOST JEEPS :: View topic - mechanical fan; can it be removed????

:dizzy:

I was looking at my cooling system on my 02 jeep liberty sport v6, and noticed that it has 2 fans, a mechanical and a electric. I'm wondering if i can remove the power sucking mechanical fan and just run off the electric. :JEEPIN:

I agree, don't remove the mechanical fan. It engages when it's needed. The electric fan only comes on when the PCM decides it needs to. You could easily overheat your engine if you rely on it alone.

lol.....

agree with who or with what?

noone in the thread has advised against removing it outside of the extended lowspeeds in high heat or low speed towing

Requires four (4) GM 11516869 mounting bolts M10X1.5X18mm (mounts fan to clutch)

The GM fan & fan clutch is designed for the GM 6.0L V8 engine with HD cooling, AC, w/towing package.

Hayden Fan Clutch PN: HY 2786 or 2986 or Four Seasons PN: 36973

I will have to look into the difference between the Hayden Chevy 6.0 and the Hayden kJ crd fan clutches, I will reach out to my vendors tomorrow and ask. The mopar fan is only $140 for the 3.7 11 blade fan and it fits perfect with no other mods. How hot is it where you live? Here in south eastern wa it regularly reaches 100+ for a month or two each year, some times 110+ for days or weeks and the mopar fan plus Hayden crd specific clutch work awsome

For what its worth, I have the 3.7L plastic fan and the heavy duty best phentermine over the counter clutch and it has performed flawlessly down here in the SoCal desert. Summer temps are in the 105 and hilly desert terrain. Also I drove the jeep to MOAB last year in April and ran some of the Badge of Honor trails and never overheated driving there or while on the trails.

I don't think you can go wrong with either fan you choose. Good upgrade!

Good to know about your fan working condition.
can you tell more details about fan you are using? So that other ppl can also have it for their use.
Thank you.

Yes,the mechanical fan is part of the HD cooling and aids in low speed cooling when towing.

Many Liberties only have the electric fan.

So just to be clear, I can remove the mechanical fan and fan clutch and just run off the electric fan. But Its not a good idea if i'm planning on towing or low speed wheeling. please correct me if i'm wrong.

with a 2002 with the better rad, unless you do a bunch of crawling in a high heat state like AZ or something, i wouldn't think twice about removing it even if it's removing it 9 months of the year done alot of extended idles, crawling in 4 high in powder sand, never had any heating issues without a mech fan however, it would probably make me 'feel' better during the peak of the summer when i'm out camping but other than that, it doesn't need it, elec fan rarely ever, EVER, comes on as it is

You do know that the electric fan is the prime cooling fan,the mechanical fan is only a aid at low speeds like when towing.The mechanical fan will not engage until much later after the electric fan is already running and the engine temps reach 230 degrees or so.

There are fan clutches that engage at lower temps such as the Hayden 2905 at I think 195 vs the stock 220 degrees also there is the 11 blade chevy fan upgrade.

Why is everyone installing a Chevy fan when the 05 3.7 fan fits and it’s a direct replacement? Our shop use to build airplanes and the books on prop design shows more airflow under 3500 with the mopar fan part number 52079654AE and the stock crd 5 blade steel flows more above 3500 so for what it is just get the stock 3.7 mechanical fan… I run it on all mine (3) and the overheating is gone, the one I drive use to overheat pulling a grade in 95 + heat with the ac running and I’d have to slow to 60 with the ac off but with the mopar plastic fan it won’t pass the half way in 110 doing 75-80 up the same hill with the ac on… I have been running them for years now and they also fit the grand Cherokee with the 5.9 so it moves some air at a lower rpm for sure Sent from my iPad using Tapatalk

The 11 blade GM fan allows you to use the Hayden severe duty fan clutch designated for the large 6.0 V8 GM trucks with heavy duty cooling system with AC & towing package. Also, the GM fan can be purchased at about half the cost of the OEM Mopar plastic fan. The GM fan & clutch are both available through NAPA and other parts distributors. If you reside in colder climate locations, you may not really need this mod! Having pioneered this modification several years ago due to the poor cooling in the very hot high humidity conditions of the south when towing or driving in town in stop and go traffic with the stock Mopar fan, I can certainly attest to the fact that adding the GM fan & HD clutch has been a vast improvement. It helps lower transmission temperatures when towing and greatly improved AC performance at low speeds in town in 100+ temperatures & very high humidity conditions.

It's your choice... Just a slightly better mousetrap.

Here in the southeast in the summertime, we see 100+ days with extremely high humidity (over 90%).

For what its worth, I have the 3.7L plastic fan and the heavy duty clutch and it has performed flawlessly down here in the SoCal desert. Summer temps are in the 105 and hilly desert terrain. Also I drove the jeep to MOAB last year in April and ran some of the Badge of Honor trails and never overheated driving there or while on the trails. I don't think you can go wrong with either fan you choose. Good upgrade!

Sure but there is not much to tell about it. You can use the GM 11 bladed fan and the GM fan clutch or do what I did and use the plastic fan from a gas liberty and the heavy duty fan clutch (made for towing). They go in place of the metal fan that's in the CRD and moves more air when the jeep is at or near idle. Helps keep the temperature down and the other benefit is your AC is just a bit more, at colder, at least it is for me, your mileage may vary. Only reason I went with the gas liberty plastic fan is I already had it laying around from another liberty that I used to own so used what I had.
