Polaris IQ LXT
Hello everyone. I have a couple questions that will seem silly but have me stumped.

I recently purchased a 2013 Polaris IQ LXT (Turbo) for my spouse. It is a very comfortable (and powerful) 4 stroke snowmobile.

I always service my sleds annually, and try to do as much maintenance on my own so that I can learn and know exactly what has (and has not) been done. Recently I completed an oil change on the unit. As part of the oil change, I was required to remove the airbox in order to access the oil filter (boy that was a bugger to get the cover off). Once I reassembled everything, I found that there was a hanging part that I cannot identify where it should be properly mounted. Please see photo 1.

If I had to guess, it is a vacuum line of some type. It has a clip, but I cannot find anywhere to mount it so that it does not bounce around. Also, please note that one side has an end that appears to be for a hose to attach. I could not locate any (air or vacuum) hoses that would go to this. SO, my questions relating to this would be (1) where does it properly mount and (2) is there supposed to be a line connected to this part?

My next question relates to coolant. I need to top off the green antifreeze as it seems to be at a low level. When I look at the manual, it suggests using a "high performance" 60/40 mix antifreeze. This indicates to me that it does not need to be OEM. However, everything that I can find available is 50/50 mix (including the OEM coolant from Polaris that uses the part number found in the owners manual). Did Polaris go to the 50/50 mix and I no longer need to worry about the 60/40 mix?

Lastly, I went ahead and changed the chaincase oil. When I drained it out it was obvious that this was needing to be done (although the prior owner had indicated that it had been changed when the oil was done prior to my purchase). In any event, the manual indicates to add 9oz of fluid and to be careful to not overfill. It took 11 ounces to get the level to the minimum safe level on the dipstick. Is this normal?

I appreciate any insight or advice that can be provided. Thanks a bunch in advance!!

Well I never owned a FST but I can answer alot of this.

That item in the pics is the boost control solenoid, it has an open port to bleed off pressure to control the turbo waste gate. Common part on any turbo charged engine. Looks like Polaris mounted it below the air horn to the turbo inlet which wouldn't be fun to get at now, see the parts diagram in the link below. Probably just zip tie it to the coolant hose at this point.

For your second question, Polaris switched to extended life OAT anti-freeze in late 2014 and modified the mix to 50/50 then. I don't think they even market the old 60/40 ethylene glycol anymore, you can still get it in concentrate at NAPA, Zerex brand I think, and blend your own. Your call on that one as theres endless debate whether to stick to the old or use the new.

I wouldn't sweat the last one too much. Any capacity is listed at standard temperature, 68F. I cant say I've ever measured out the fluid, just added until the dipstick was happy. They just dont want you to grossly overfill it and blow out the seals.

That was an absolutely FANTASTIC reply! I really appreciate you taking the time to answer my questions. Your responses all seem reasonable and I will follow all of your advice. Again, I appreciate the time you spent providing the response!
