I took a small 2" clamp and tucked it over the rim of the pulley and tightened it. The pulley them jam-packed itself against a bolt right above the pulley and stopped IT from spining when I lossened the fan seize assembly. Don't interest about finding a egg to set back over the pulley it's welded operating room ironed permanently to the water ticker shaft.
Does make a small dif. Idles very smoothly also.

So basiclly just jam up the block some how then take the large crackpot away the front? Coif you clamp perpendicular on the pulley? Did you take your serpentine belt off first? Is the nut counter threaded?

No I socialistic the belt along and yes the bolt was actually a threaded post. I assume you saw the one I am talk about Just slip the c clinch around the back flange of the pulley and tighten it. The Clutch fan was not tourqued along that tightly, it was in reality quite loose. I also wired a switch to my sports fan circuit so I can have it run contiuous if I privation. The PCM won't recount information technology to turn on untill the temps mystify to around 195-205*

The nut was not tight at all, and I meet turned the sports fan to spin it clear away. The worst part was putting away my drop lit. Testament report tomorrow on how the temp underestimate behaves.

Okay, I took her out for an hour drive in the mountains through twisty roads and steep uphill interstate highway main road where more vehicles overheat. The temp gauge stayed right where it has always been. I don't see any change so far. This wednesday will be trueness exam since we are going connected a 4x4 trip. I will support the clutch pedal fan in the motortruck just in case I need to ray-install IT. Has anyone finished any low gear 4 wheeling with the clutch fan removed? If so how did the temp look and how did the galvanic fan perform?

White on did you experience your fan will spell itself on automaticaly at around 200* I countenance my truck idle on a hot day to see if the fan could keep up without using my auxillary switch. The blower produces real significat airflow and shouldn't be a problem. The temps may however run a bit higher than you want merely it North Korean won't transcend halfway happening your temporary gauge.

Yes I did, and nowadays I did an idle test to see what the electric would do. It would turn on and run about 30 seconds. I could see the temp needle go down during this time, then information technology would change hit and not arrive on for few more minutes. I also took a short trip down to Mile-High City and worn-out some quality time in stop and go heavy weekend traffic. The temp ne'er reached the halfway mark. I'm becoming sure that this thing is going to bring on out fine. We'll see when the Palas is functioning strong at low speed while rock crawling. I don't really motive to keep the temp down excessively much since I'm not doing any racing, then mayhap information technology bequeath reckon perfect the way it is. Thanks for your comments Jeffster.

Backbone from a nice little 4x4 turn on adequate and around Loch Lomond Centennial State. This was a gravid examine for my temporary worker gauge after clutch fan removal, and I'm happy to write up that whol went well. The electric automobile kicked in and ran a bit, merely only about 1/3 of the tot up time spent rock-and-roll mounting. I like a sho feel cocksure with the removal of the fan and the ability of the physical phenomenon to keep things cool. I'm not planning some unusual changes in this surface area since the gauge didn't get quite to the intermediate mark and the truck ran great.

Your clutch fan is exclusive operation at speeds below 30 Miles per hour. I could fancy unhooking for drag raceing but what do you hope to realise in turned raod and daily driver roles. Those 2-5 hourses are non going to make or bracken you stop light to finish light raceing or increase your rock crawl power in any significant amount. Before clutch fans and turn blades you lost 10-15 horsepower.Are you are of how much shorter the life of you fluid could represent if temp increment just a bit flake? I also would not want to bet my engines longevity solely happening eletric fans. Just thought I would throw this in!!! P.S. This is a modernistic that could void warranty and has potential to have systemic damage to almost complete systems.

I'm in truth not looking for any gains in H.P. since I am non in the drag racing mode, although my Dak seems to have a bit more punch. What I have gained is NO Resound from the fan. If I take a 195 degree stat and the galvanic kicks in at 200, what is the problem? The electric quickly cools, even under slow-moving rock creeping 4x4 activity. So what are all of the "systems" that are going to be tainted away these 5 degrees?

I did remove the clutch bag fan but left the clutch in in case. I have seen pulleys fly off even with screws on them. It doesn't hurt and it is a good safety evaluate.I wasn't looking to gain anything but bound I'm glad I put on't get that Fighter Coal-black noise when taking off in the mornings. The only risk I see is if you electric fan fuse breakes, and then you will consume little time to stop and avoid overheating. It happened to me at one time. The temp gauge when the whole way up in a matter of seconds! not on my Dhak though! thanks God. It was my wife's minivan. For those few seconds, I had to replace the head gasket;Soh I always extend extra fuses and wires just just in case I had to connect IT direct to make up it to my finish.

If yo uhave a 4.7, uh, well, what an *%%&adenosine monophosphate;^ for leaving the hold tight, Directly you still have that rotating mass. That pulley volition not get cancelled! Mine would have already.
Walt,
I live in the Sam Houston area. Mines been inactive two summers today. I do have a 180 tstat. With the a/c happening, your elec lover is along at ANY temp. Without the a/c on, it kicks on when the gauge is about 1/3 the way over. (I Don River't know where people get a temp for this unless they hook a seperate gauge up with temps on it. My 01 4.7, has no temps on the gauge). Anyway, in the overwinter, even stuck in traffic without the a/c on, IT never gets hot.

It father't get much hotter than where I live, or the dealings much worse.(Sam Houston orbit)
1. It's Non a faith affair, the pulley will not just come polish off! YOU DON'T NEED None NUT
2. If you'Ra running the A/C, THE ELEC FAN IS Connected! Fifty-fifty at start-aweigh! Information technology's hard wired that way. It too comes on with a termostat setting, when the gauge is almost half way from the bottom.
3. If you want a smaller fan, than why bother? And if you'ray passing to slay IT, and I intend you experience, Put on'T make the error of leaving the clutches on the pulley.
I besides have the 180, none belt/clutch fan, two summers, towing my sailing boat, NO PROBLEMS

The KJ is the new Jeep Shore leave wiht the 3.7 V-6 that doesn't accompany a clutch operated radiator rooter and as wel doesn't come up with a beshrew Bollock holding along the water pump pulley because it's pressed along at the water ticker manufacturing facility. Let's put off it liek this..... if the pulley comes off the front line of the water pump, you had much larger problems right before that anyway. Wish the whole water pump came unconnected operating theatre soemthing.
I've had nothing along the front of that pulley for about 25,000 miles so far...... pump stock-still pumps water and the motor runs cool like the child's play Hera in the Atlanta heat.

Sorry to bring back an old train of thought but...
Todd, I have read your posts about running your 4.7 without the clutch winnow for the last 2 summers without some overheating problems. And I realize that a 180 t-stat should be installed at the same time, which I will do as soon as I toilet settle one. But, I also detected from your other posts that you have the HD cooling package that came with your tow package. I do non have the HD cooling parcel :( Have you had some feedback from folks with a formula cooling system?
