Hey Z! I expect to have to do that in the spring. I just wish we would get some more snow now!!
2012 Polaris RMK's Running Hot?

Bingo! My thoughts exactly. Consistent high temps at slower speeds even in fresh. The 2011 DOES NOT get near the high temps as the 2012 in exact same conditions. I had my dealer check for air in the system, etc and they found no irregularities. Has to be the flow of coolant thru the system - makes sense to me.
Thanks for you input on this. After January 3rd I will have my sleds back from rentals to where I can test several sleds and really post some results concerning the temps with and without scratchers. I am also consuming a very small amount of oil on the 2012's. I am going to start measuring accurately. I am concerned that this small heat problem now will be huge under spring conditions.
Rockin,
I forgot to mention that the cooling system on '11 models appear to be set up the same way so I doubt that it is the design, per se, that has caused increase in temps. from the '11 to '12 RMK..............I just feel the design is questionable in that it doesn't make the most efficient use of the front & rear coolers.............If you're interested, you can browse the on-line parts catalogue at Pure Polaris...........
There are a lot of modifications that can be done to improve the cooling system on these machines however I can sympathize with your frustration in the fact that you shouldn't have to be "doing" Polaris's engineering for them by installing additives in the coolant, changing snowflaps, adding aux./extra coolers, etc...........Especially when competitors produce machines with cooling systems that perform properly "out of the box"..............
In your situation, the cheapest solution might be to install Water Wetter and communicate as effectively as possible to your customers the need to use the ice scratchers & monitor the temp. display.............
FYI, I own an '11 Pro so my post is not "brand bashing" in nature............

They all have scratchers now. Until this year, a regular model RMK didn't need them under these conditons. Even Yesterday with new snow on the trail, one of the 600's hit 205. I have a feeling that something will be discovered before too long to why this is happening excessively. Thanks for the input.

Im just glad Poo decided to put temp gauges onn these sleds
Mine went down yesterday
Was riding some hard pack snow and went into a field to cool things off
Was playin around and watched the temps go from 123 all the way up to 198
No temp light came on
I shut it down and opened the panel and there was ZERO coolant in the bottle
Lid still in place and the engine bay was dry
Cant figure out where it when but it looks like maybe a pinhole or something in the front HE????
Not sure but i lost it fast so maybe not a pinhole
Ran great and normal temps all day them boom, nothing
But it was all piled up near the front of the skid
Goin to the dlr tomorrow to see what happenned

Hate to even say it but could there be some leaner mapping on the '12's that you guys are getting into at trail crusing speeds that could make them run hot?
I measured oil consumption on three 2012 600 rmk's yesterday. All three sleds used 4-5 gallons of fuel. Two sleds used 8 ounces of oil and one 10oz. Ski-doos on same ride, 20 oz and 26 oz. There is a serious problem going on here.

There has been a lot of discussion about the oil consumption (or lack there of) with the PRO 800. There are many ideas, opinions, theory's etc. but I have not seen any official word from Polaris on the oil consumption, what is required, normal, and why they burn SO MUCH less than older Polaris 800’s. I fear it’s the pressure from the EPA, driving this. If the low oil consumption is not bad for the engine, then I would like to know what has been done with the design of this engine to require such a significant reduction??
Polaris... if you are listening, please let us know what is the reasoning behind the reduced oil consumption....

Is this accurate for the 2012 800 Pro RMK? I was out in Walden, CO and I saw 200 degrees but no light (briefly was off in the first powder I could find). I was riding with Summit 800 e-tech and he saw his light come on so I don't think we're alone in running hot in poor snow.
Just going to throw this out there but since it seems some people are still experiencing hot temps even with scratchers down, do you people have alot of things installed on the tunnel? (tunnel bags,gas racks, ect...) Dont know if maybe that could affect the efficiency of the cooling process? My tunnel is bare and Iv never gone over 130* with scratchers down in almost all conditions. Just a thought?
That's roughly 70:1!!!
I wonder if the oil injection pumps are adjusted correctly???
It might be worth it to pre-mix the fuel in your tanks with about 10 - 15 oz. of oil to see what effect that has on your coolant temps until you can get the machines to a dealer to be looked at............

This topic has been beat to death. Many (including me) are turning up our pumps, and running oil in the gas tank. I still have not seen a good answer for the little use by these engines. You can do a search of this forum and find long threads on the subject, but no real answer or proof that for some reason these engines don't need a more normal amount of oil from the pump.
it may really not be an issue, but I find it odd that the PRO 800 uses less than a quarter of the oil that my wifes old 05 Polaris 600 RMK used???
I like the idea of not having to buy so much of this expensive oil, but I wonder what the long term ramifications will be??
I add extra oil to the fuel tanks daily until I feel comfortable with what is going on. Heard that several 600s went down this year due to oil pump bleeding issues. My dealer bled all of my oil pumps.
After seeing the lack of oil consumption I am not confident that the bleeding is the only issue or solution.

I'm a little worried about my 800. It's on par to use about 4 tanks of oil in 1000 miles. That seems scary low....
130 miles on her so far and it looks pretty close to half a tank of oil.
Edit: It's been mixed 50:1 so far though for break in. I think I should turn up the oiler and mix at 100:1 now.

Wow if I would have known the issues with the 6 I would have passed on Polaris . Its the wife's ride and I wanted it to be an excellent experience not a hassle of mixing fuel and oil and worrying about heating and cooking the motor , sheesh our season is to short to be plaqued with major issues .
I wouldn't worry too much man. From the sounds of it you haven't even got it out for a ride yet. Just take it out and see what happens. I haven't had any cooling issues on my Pro yet and the Pro is the one missing one of the heat exchangers to save weight. On fairly hard snow I saw 145 with no scratchers down. I'm sure I'd be down at 125 with the scratchers.
