 Ice buildup in tunnel Polaris Fusion/IQ
When we took our short tracks to the snowies this past winter, two of us (fusion and iq) had trouble with large amounts of ice building up inside the tunnel, to the point that the suspension would sag even without anyone sitting on it. Is this a common problem and is there any fix for it? The other guy with a firecat didn't seem to have the same problem...
Hoping this is something we can address over the summer...

I'd guess it's from the heat exchangers and the snow melting and then re-freezing. The Cat probably has a different heat exchanger set up, and doesn't cause the ice build up like the Polaris. I had a Fusion, and that was my problem too. The coolant going through the foot rails causes the sides of the tunnel to warm up enough to make the snow melt and re-freeze. I think the IQ has the coolers all the way down the inside of the tunnel, and that would cause the melt/re-freeze too. The Cat might just have the cool in the front by the driveshaft. Not totally sure on that though. I don't think there is much you can do about it, except try to clean it out as much as you can.

Depending on the $$$, have you thought about an aftermarket tunnel?

Before your trip, spray the top & sides of your tunnel with TEFLON spray lube

Is the underside of your tunnel bare aluminum or painted/powder coated? If it's bare aluminum, snow/ice will accumulate faster. If its painted or powder coated, it will not build up as fast. If it is bare and can't or don't want to paint, drop the skid and track and polish the inside of the tunnel, this helps a little too. I have an acquiantance that put a new Vanamburg tunnel on his MM a few years ago, had some ice buildup problems until he polished the underside. Just my observations.

Interesting idea. I did a google search and this came up:
http://www2.dupont.com/Consumer_Lubr.../silicone.html
"Snow and Ice Repellent." I'll have to give it a try. Riding off trail is the only time I've noticed it happens. I'm fairly sure the underside of the tunnel is bare aluminum, but I can't remember to be sure.
Do they do something different with the cooling system on the switchbacks/RMKs? Seems like a poor design if you think the sled will ever be off the trail.

I have a 2010 with tunnel protectors and a cobra track. No ice build up. I have a 2007 with a ripsaw and NO tunnel protectors. Major ice build up on the 2007.
I know the tunnels are different but I would put tunnel protectors on. As long as you're in prime conditions like out west you'll be fine. I'm going to remove mine from my '10 because they cause the sled to get hot in non prime conditions. Polaris dropped the ball on that one. So I'll have some for sale soon if they'll fit your sled. I don't have studs anymore so I don't need them.

I'm interested, but I ride in non-prime conditions quite a bit (particularly in Wisconsin). Are both your 07 and your 10 IQ's?

Yes.
