When the engine or ambient air temperature is cool, the viscous clutch turns the fan but barely. When the engine or ambient air temperature is hot enough, the viscous clutch through control of the bi-metal switch in front of the viscous clutch engages the fan. If the silicone fluid has collected at one point after a long period of sitting, the viscous clutch can also engage the fan even when the air and engine is cool until the silicone flud is properly distributed again at which point the viscous clutch will disengage the fan. The viscous fan clutch also limits the fan speed at higher driving speeds where the fan is is not needed as much.

Hence the reason the sound of a jet plane taking off at first when you take out in the morning until you get about half a mile down the road or around 3rd gear then it is pretty much back to normal.Until the E-fan I hated that first take off of the day.I had an S-10 that done the same thing and it was even louder than the Jeep was. It sounded and felt like you were taking off WOT in 4 Lo .

just an update. the drain plug on the oem radiator is not 3/8 or 1/8. .. 10mm type bolt.. sorry i am an idiot when it comes to converting metric to standard.. but it somewhat along that size.. imma head to ACE today and find a t fitting

It could be a 3/8" NPT (National Pipe Thread) size which is different from standard SAE 3/8". That's what my radiator was threaded with for the tranny coolant lines and I wouldn't be surprised if the drain plug wasn't the same size.

heres an idea for your temp sensor or switch for the e fan.

on the driver side of the block in the middle between the precats right below the freeze plugs you can see a "block drain plug" that would be a perfect spot for a temp sender or switch for the efan. it will be grounded and have a exact temp of whats going on in the block.

the trick is your exhaust 1/2 covers it so you would need to remove your pre cat section of exhaust aaaand by removing the drain plug you will be vacating all the coolant in the block. but in my opinion it is the ideal spot just a bitch to get too.

hey all im wiring my E-fan.. Everything works great but I dont know which wire is the key ignition switch.. You know when you put your key in and it will power.. I dont want the fan to run then the ignition-key is out.. any wire in the ingine bay? this is an 05 TJ..

I can run it from the steering colomn but that is a last resort. I dont want to reconnect wires..

any ideas? thanks

i used a volt meter to find the one i'm using now ( i would recomend you also at least double check the wire before you use it too. I wired it to i think something that said "fuel pump relay?" no idea exactly however it was 12 volts when the key was on ON position and was 0 on off.. works great for now.

Not wrapped in tape for visual effect. I wrapped it after the pics.




On the writeup it said to look for a purple wire with black stripe i think.. i got a solid 0 or 12 volt reading so i had to look for something else.

any how I's just waiting for a response for the ignition wire?

Tripp just so you know at first I used the 200 degree temp sensor.. It reached boiling point and the fan did not go off.. I checked all the wires and they were fine.. However they sent me both the 185 temp and 200.. because the 185 temp sensor was in the kit.. and an addition package free of charge was the 200 deg. temp sensor. when the fan did not turn on after 213 degree or so I switched to the 185. and what do you now the fan turned on about 195-200 or so. I think the T fitting makes it read the temp incorrectly.. or the temp sensors are rated higher than advertised.. the fan turns on and shuts off at 205 or so.. it works great.. i did not drive it yet but, just by revving it I feel a better throttle response...

for buying a cheap fan the jeep vibrated slightly due to unbalanced fan fins.. but not enough to annoy me.. feels like the jeep is idling.. again not a luxury car..

so yeah Tripp just get a 185 temp sensor and call it a day..

tripp do you know what wire is that from (relay)? I dont think I have it.. maybe due to me having an automatic? I know for sure I dont have the big black and blue wire.. I gave up after a few wires.. due to it getting dark.. I'll try again tomorrow..

on my wiring kit from ebay.. they automatically did the + wire from the battery directly to the wire you want which is similar to the ignition being on all the time (for that relay)..

See how its looped? you cut that wire off as close as you can to the other wire that goes to the battery and then connect another wire so you can run it to the ignition +... You can actually pull the plug things out and solder them instead of having to tie them up and wrap them in tape and stuff.

the one I got actually has a batterey wire and a seperate ignition + wire. but I am trying to find wich wire to splice it from the jeep.. i'll test all the wires tomorow.. my kit even came with a 30 amp circuit breaker for surges.. they did good by me,.,

so what did you end up doing with the temp sensor?

my eyes tell me if i have to click it.. my brain tells me if i'm more than 30 seconds at a stop light, my hands turn the switch on and off, while the temp sensor is resting in my tool box. Thats about it.

man thats a pain.. just do what i did and get a 185 degree temp sensor. not saying its the best way but you should relax when driving.. airplanes pilots have less bottons to wory about..hahah

lol.. actually not as bad as you think man.. my temp never goes above the 210 mark (fan off) unless i'm in traffic or stop at a red light for more than a min or two.. thats why 30 secs after i stop in traffic i turn on the fan...

One reason your temp reading is higher than it actually is, is because your factory guage sensor is right beside your hot manifold and reading at least 20 degrees higher than it really is.Also just grab a test light and pull the cover off the PDC and test to see what fuse or relay terminal comes hot when the key is on and hook to that I can let you know for sure which one I used tomorrow in the day light but all you got to do is test the terminals to see the one that is hot with the key on and not when off I can tell you the Maxxi fuses are going to be hot and not switched power.I think I ran mine in to the fuse box inside but I will let you know tomorrow.

Another thing I see that will not work as well either is you used pipe thread compound on all the contact points of the fan switch and although it may work now it may also fail down the road because it requires ground to activate the fan so if you must use that for it to seal I would run a small wire from a good ground source to the outside case of the temp switch to make sure it gets a sure ground.

i ran a t fitting like that for a while and my temp senders where never right. it always showed i was running cool and when i put the thermal gun on it it it was 15 to 20 degrees off.

that picture just appears to be close.. it is actually a few inches away from the manifold. all i know is my guage said 210 it was boiling.. so it cant be no more than 5 degrees off.. I can live with that.. your right about the thread compound.. I thought of that after everything was installed..

that's why i dont want to do it like that. I want the stock temp gauge the way it is, i dont want to mess with it and then have to guess if its right.
I rather have a right gauge and have to click it by hand then to have a wrong gauge and have no idea what i'm really running.

i cleared all the thread compound and have droplets of leak on the after market temp sensor.. tripp i dont like it either but I already bought it.. i might buy a sensor you put in the radiator fin.. i drove it today and the fan turns on quite often..

the temp sensor in its regular position sits a hair under 210 now it sits double the hair.. so i imagine its not that off..


i wonder at what temp does the clutch fan normally turns on?

no idea.. i barely run my fan (again only in traffic) and it stays bellow the 210 mark often.. you can actually notice it when the engine thermostat opens as it goes down to 195ish in about 30 secs..

Rawkon, please post pics, i looked around but could not find anything on my 00.

I personally would rather have my fan kick on a little more often than it has to rather than trust myself to remember to turn the fan on manually.One slip up of not turning it on and it could mean disaster.

if you dont have the precats you might be able to get to it without removign the exhaust. you still may want to remove the Y pipe for ease of access
