Hi all,
I just returned from the National ATV Jamboree in Fillmore, Ut. last week. On one of the rides, my Quadrunner 4x4 overheated. I'm thinking of purchasing the cooling fan accessory for it.

Does anyone have any experience with fan installation, operation, effectiveness??

Thanks,
Mark

 

I put a cooling fan on my King Quad, for that very reason. I was concerned about going to WV. and running hot up in the mountains. Material cost me about $10.00 and I made the frame for the fan at home. If you intend to spend premium $$$ on the Suzuki Fan, I would suggest you make sure it's designed to suck air through the oil cooler as well as blow on the engine for cooling. good luck.

Chuck,
Thanks for the reply. Since I'm not much of a do-it-yourselfer, I did plan to buy the Suzuki fan. It's supposed to integrate with the existing electrical system and be thermostatically controlled, but costs close to $300!!! It's supposed to kick on when the oil temp exceeds something like 248F and shut off at 230F. I don't know how it will hold up during stream crossings though. What I think is interesting is that in Australia (guess it gets hot there) the fan is standard equipment on the KQ and Quadrunner. That info is based on the Suzuki service manual.

You're the only person that has replied so far. I guess not many people have tried it.

Guess what Mark, brake lights are standard in Sweden, too, like fans for Australia. There are a few riders here in the forum that have installed fans on their Suzuki's. Everyone has his preference and if you can get help from some of the more informational types (you guys know who you are) they have a site for all kinds of mods to Suzuki Quads. Some pertaining to what you're looking for. I think we just got somebody's attention... You should be mechanically and electrically capable of doing these mods yourself or have someone who has little knowledge about this type of thing before you decide to disassemble. The flip side is; how often are you going to ride in an area that may over heat your engine? You may not want to do the modification if it's once a year or so. Your call...

I found a 12V - 100CFM fan in Northern tool for $6.99. The only catch is that you'd have to either find a temp switch or switch it manually. I'm thinking of putting this on my King. Summit Racing has a fan relay with a thermostat for $59.95. This one would come on at 200 and go off at 185.

Hey Chuck, what did you use for a switch for your fan?

 

Chuck,
Good point on the frequency of overheating. This year being my first ATV Jamboree, I was surprised at how hard people ride. Or maybe I'm just a wuss but I don't think I'm that much of a beginner.

I think having a cooling fan would, as a minimum, give me peace of mind. My kids ride the ATVs a lot too, and they don't have a clue about overheating. I've tried to coach them about sitting around just idling the machines, but wonder how much good it has done. [img]i/expressions/face-icon-small-smile.gif[/img]

I can do the mechanical mods, but I probably couldn't gen up a fan arrangement like you did from scratch.

I hope others do respond. Can you send me the links to these sites you're referring to?

Thanks,
Mark

 

I too have a quadrunner 4x4 (2000 model). I used to have problems with the machine over-heating as well. The problem was that I was contantly getting mud in the radiator fins, then it would over heat. The way the 2000 is designed is not too good for heavy mud riding. There is a platic guard in front of the radiator with approxiametely 1/4" holes all through the guard. These holes would let the mud right in and into the radiator. I took the lights and guard off and cleaned out the radiator with a hose (don't use a pressure washer) then put the guard and lights back on. Then I took an aluminum window screen and cut it to fit behind the lights. I attached it directly to the current plastic guard. It really kept the mud out of the radiator, I have never had an over heating problem again. The screen has been compltely packed with mud, but the fan kept coming on, cooling and turning off just fine because the mud was kept out of the radiator. Simply take the screen off to clean it and put it back on. You really need to clean out the radiator well. Spray a hose in it until water passes completely through and is clear. Hope this works for you.

 

Dave,
What size engine is your Quadrunner 4x4? My is a 2000 Quadrunner 250 4x4 and doesn't have a radiator, oil cooler, nothing! It's just a straight air cooled motor.

Sorry, I assumed it was the same as mine (500cc). The 500's are liquid cooled.

 

Hi MikeR. I used a simple twist on/off switch in conjunction with a light so I know when the fan is on. I don't have temp control but it seems to work decent if in fact the oil temp light does come on. The fan is the same fan you talked about from Northern Tool. Some times I just turn off the engine for awhile and let the fan blow.
Mark, I can't find the E-mail address for the Suzuki Modification sites. That's why I was hoping to get others here to help you. Sorry, I'm not gonna be much help on this one.
Good luck,
Chuck
