Shouldnt it be hot before the fan kicks in?? I have a fan switch on my 400i so I can turn it on when I want but it wont come on by itself untill it reaches a certain temp.

I wouldnt think that would be good if the fan stays on in some deep water or mud, Do all the 500's do this?? The 400's hardly ever come on and run really hot that is why I put an override switch on so I can cool it down a bit when I want (before going into deep water, or just whenever)

If you go into some deep water with your fan running is it not hard on it?? I flip mine on for a few seconds before going into water, that way it shouldnt come on if I have to work it. ANd yea if it fails it will fail to the on position.

My 500s fan only runs when the motor heats up. If its below 50 degrees and Im moving atleast 10 mph the fan never runs. if Im working it hard, dragging stuff around, or its hotter out then it runs more frequent

Trey; According to my 2001 service manual the fan is only suppose to come on when coolant temp reachs 190-200 degrees and shut off when gets down to 177 degrees. Being on all the time would be very hard on the motor and when the thremostat opened cause larger than wanted engine temp variations. Also the electrical repair sections says to test the fan by hooking it to an external 12 volt power supply.

Trey; It's in section 5, page 5-6. If you have the wiring diagrams you will see there is power to it all the time and the temp switch gives it ground.. I know one way to check if the switch is working. Ride in deep snow untill you pack the radiator full of snow. Will over heat everytime, even in sub-freezing weather.

tta583; Actually a properly designed switch would fail to the "fan ON" position. That way at least you wouldn't overheat and burn something important up, like your engine.

HI
I have only had my '01 400 2x4 man. for a couple months, but when I turn my key all the way the fan comes on as well. Perhaps they changed something. I bought mine from a friend of a friend and it only has a couple hundred miles on it, but he knows his stuff in the ATV world. I can't imagine that being over looked, so my curiousity is peaked. Keep us posted Trey with what you find out.
Regards
Marla

Trey,
I have an 01 400 manual. I am guessing they are the same quad just different motor based on looking at the parts diagrams at Alpha Sports. Both quads use the same diagrams save for notes on the 400 vs. 500 in the ENGINE AND EXHAUST section. Any way my fan comes on as soon as I turn the key to run.

I have only had it about 6 weeks and only had a chance for a couple of rides, only one of which was over anything other than more or less flat farm land. Given that, I love it. I have had to reacustom myself to a quad, I have not been on one but a few times in the past 15 years. Back then most (like 99%) of my riding was on dirt bike. I decided to buy used, and avoid the payment, because I wanted to make sure I could use it for what I envisioned plus I wanted to get a feel for real riding spots. Any way, it is dead stock. I have been toying with getting a jet kit but have yet to decide. It runs well as it is, I think a rejet could pep it up a tad, but to be honest I don;t want to start dinking with it. As soon as you start, well you know the rest....

Hmmmm,,,Well, then let me say mine comes on with the key, not that this is right, but that is the case. Perhaps I need to do some trouble shooting myself.

I am definitly interested, all ears so to speak. I have only had the quad about 6 weeks, most of which it has had to sit. I just had the chance to finish up all of the spring cleaning type of work (minor odds and ends repairs, new fluids, etc), all the things I do when I get a new toy so that I KNOW what condition everyting is in. If I have a problem I would like to get it niped before I start serious ridding for the summer.
Also, for what it is worth. My dealer struck me as a real sharp guy. He offered and fixed a lot of things I would have accepted as normal wear and tear as the quad was used. A couple of things he even pointed out as I was not familure with the model/brand. If the fan was acting funny I am sure he would have realized it. Then again, you never know.

I wonder if there was some change along the line. I have to go a 'hunten again but I swear I saw a date some place on my machine. It seemed "early" to me, like late '00. I would have to find it again. I took a look at the parts diagrams over at alpha sports, sure enough I found a temp swith. I have a new plug to swap in this week end, while I am in there I will dig aroud and see if I cen see what the deal is. Even if it failed I would have guessed it to have failed to its at rest state, or open, this providing no ground and no fan.
Interesting
Poor Trey, he came looking for what should have been a black or white answer and all he gets is grey.

I would agree, however I am thinking automotive. I just seems that when I have run accross a switch such as this in a car it will fail in its natural state, generally open. Idiot light sending units, some gauge sending units, various control switchs. My favorite ones are relays uses to control electric fans. Most automotive relays are off (open) naturally, then close when voltage is applied. I have seen several overheating problems due to failed relays that remain open thus never starting the fan.
All in all I am sure I am backwards some where along the line. Trying to compare auto to quads is proving to be the old apples to oranges arguement. Never the two shall meet.

Good afternoon !!! I have a 2001 Arctic Cat 500 Manual ATV and I have got to replace the fan and radiator...I have already purchased these items and have disassembled and ready to reassemble, however...After replacing the old fan with new, I wanted to make sure the fan/ motor worked and it did not...Usually when you turn the key on the fan motor kicks on and the fan will start to turn...The fan was working when I took it all apart, but of course the radiator and hoses were assembled. I have checked the fuse and it is still good, I guess my question is, should'nt the fan turn without the radiator and hoses connected?
Other than this minor problem, the cat is all original and I have got about 2000 miles on it and it has never let me down...Do all the fluid changes about every 400 miles and she'll have all 9 lives.......Thanks....Mark (Arkansas)

I am almost certain that when you turn the key to the on position, the fan kicks on, and it shuts off when you turn the key off. As a matter of fact, the fan stays running constantly on my 500.
Posted by: TREY1097
Maybe it is me, but I thouhgt it came on when the ignition was turned on..I have called the local dealer/service and he is looking into that for me..When I do in fact find out, I will let ya'll know. I have had my Cat in water just over the front rack and never did hear the fan hitting the water, but then again, never really thought to listen...Once the water gets over the gas tank however, the Cat does not do so good...Have sunk mine twice !!! Not on purpose, just one of those huge holes that were not supposed to be there..I live on Bull shoals Lake in Arkansas and do a lot of riding around the lake and up the creeks, etc..
Has anyone got the 2001 AC manual on CD ? I believe the manual is around $60 at dealer..
But i am sure it is the paper manual..

Brent,
I thought I remembered hearing that fan kick on as soon as I turned the key to start...Thanks for confirming....Have you been happy with your Cat? I've been pretty happy with mine...Looking into the new 650 but own the 500 and don't really want the monthly payment again....Have you done any modifications to your Cat? I am looking to get a little more speed out of mine...
Thanks,
Trey

I called the dealer and he finally let me look at the manual to answer my questions..Yes the fan comes on when key is turned on...So now...I have got to find out why the fan motor worked before i disassembled and why it does not work now....I have checked the fuses and all is good, probably should use a test light to find out if the fan motor is getting juice. I'll keep you posted on the progress.
Posted by: TREY1097
What section in your manual or what page...I have just borrowed the service manual for all 2001 Arctic Cat ATV's...It is on CD so I have got to go through every section...As with Brent, I can remember that distinctive sound as i turned the key on the fan came on...but then again, maybe it shut off after a few minutes...I had the fan fuse blow once before and remembered not hearing the fan noise when I went to start the CAt and checked the fuse and it was blown and i replaced the fuse and it worked when i turned the key to the on position to start. I will test the fan motor as soon as i get a chance, it has been a little rainy here and the cat stays outside..No room in garage...I have got 3 IH SCOUT II's and a 23ft. Glastron Carlson Signature Series with 350 Merc. Mag I/O...My wife says, too many toys, I say not enough..Oh and I am also an avid hunter..So there is plenty toys out there for me.....Let me know on the page number....Thanks !!!!
