Any repair buffs out there?

I own a 09 Rubicon 500 and lately the ole girl has been heating up on me. The fan doesn't come on and I noticed that the temp light doesn't either to tlet me know the engine is heating up.
Fuses are all good, any suggestions where I should look for the problem?
Thanx in advance!

1. Check coolant level. If low, it will not cool and the sensors (for fan and high temp won't work in steam/air).
2. Check coolant strength. It may be froze.
3. Check rad cleanliness. Shine a light at it. You should be able to see through it easily. If there are any contaminants, it needs to be cleaned. Clean with LOW pressure water. Flush until you can see through it easily, and the water is clean through the rad.
4. It may be air locked. Find the bleed point on the high point of the system (often at the thermostat housing). Crack the bleed with the engine running and ensure you have fluid- not air.

Hard to expand much on Doug’s advice. I would check the cable that runs to the engine block for temperature make sure it is still plugged in. Most of the Rubicons I have been around have had rad trouble hard to keep clean and fan freezing off. More than likely it is a simple fix. It’s a Honda fill it up with beaver pond water and lube it with muskeg should run forever

well if the fan isnt coming like you said either the fan wiring came loose, a faulty fan or the engine temperature sensor... im leaning more towards the temp sensor because your light isnt coming on as well as the fan... the sensor should be located on the front of the engine on the jug just below the cylinder head... if not it will be to either side... make sure the wires are connected... try jumping your fan to see if it works.. if it does you know its your sensor... doesnt sound like a coolant problem to me

one question..... how do you know that it is overheating? is the coolant reservoir bubbling over?

Tuc · « **Reply #4 on:** January 15, 2012, 08:22:48 PM »

Thanx for all the advice guys....

Wildmeat, yes it is bubbling over and coming out the overflow hose on the res. I'm kinda of thinking it's the sensor too because no hot engine light and no fan working.

wildmeat · « **Reply #5 on:** January 16, 2012, 05:50:00 PM »

yeah the sensor isnt telling the computer that its overheating so no light and no fan... umm did you check the wire going to the sensor with a test light? it could be just a faulty lead as well

i worked at a very well known atv shop for a couple years about 10 years ago... then i worked in an automotive shop for another 4 years... i am not a journeyman but do alot of work for freinds and such on their machines... actually thinking about getting back into it but its hard to find a shop that will apprentice me... hence the reason i quit the atv shop in the first place

If you want some parts schematics (as well as a VERY cheap place to buy genuine Honda parts) check out Www.hondapartsworld.com

The service manuals arent there, but the schematics can prove helpful in troubleshooting/repair.

WM, I'll let you know if you nailed the problem. You are a good resource to have on the forum, thx again.

Doug, Thanx for the link!

had this on my old artic cat. first the sensor went so it never told the fan to turn on. next the fan motor actually siezed.

does the fan free wheel? if so i would bet its the sensor. if it wont free spin is the fan motor.

Tuc · « **Reply #11 on:** January 17, 2012, 04:54:07 PM »

Yes the fan free wheels.
WM, today I had some time to look at the quad. Can't find that sensor though, anymore clues on how I can locate it, or what it looks like, color, etc? Sure is a tight spot in there.

Doug N · « **Reply #12 on:** January 17, 2012, 08:45:45 PM »

Hey Tuc- pm me your email,and I'll send you the parts scematic. It looks to be on the lower, left, front side of the rad, under a switch cover.

wildmeat · « **Reply #13 on:** January 18, 2012, 09:46:57 PM »

yeah tell me about it... if its not on the actual cylinder then it has to be on the rad... prolly close to the the bottom hose...

Thx again. Doug PM sent.

Hey Tuc- didn't get your PM.

Here's some links ot the online microfiche.

It looks to me the fan on/off switch is on the lower left front of the rad. The high temp sensor is located on the left rear of the cylinder head.

If your fluid levels are good, your water pump is OK, and you are not air locked, it's pointing to an electrical problem (if the water pump was NFG, the fan should run continuously and the high temp light should turn on.)

Does the high temp light illuminate when you first turn on the key? What is condition of hte battery and battery connections?

Thanx for the help!

Will do Doug.
