Hi, I just got a new 550 touring and was looking though the manual. I noticed they did a pretty good job showing how to change the bulk of the fluids on the machine. One thing they don't go into any detail on though is the coolant. Does anyone here have the service manual for this machine? If I could get a copy of the pages for the coolant change that would be awesome.

Also another quick thing. They dealer reccomended 89 octane. Is this the norm with new machines?

 

Here's a free pdf download on a service manual on a 2009 550xp. Should be close to what you have and should show you all you need.As far as octane if the manual call for it I'd use it! A lot of the newer machines do have a higher compression ratio and may require it. Just like the turbos on most new autos require premium 93 fuel.My son found that out fast on his Mazda CX7.

Thanks alot of the free service manual! This is great.

As far as grease goes my manual says to only use the premium U-joint grease on the propshaft, but it looks like this service manual says to use the premium U-joint grease everywhere, including a-arms, bearings, etc. Any thoughts?

Also I looked at the 2013 manual and it says 87 octane or higher. I wonder why the Polaris service guy said to use 89?

Thanks again.

 

Most good chassis grease is moly lithium based and should be okay. That's what I used in the shop on everything. Probably said that because of the manual (87 OR higher octane)Try a tank full of 87 and see how it does. If it's sluggish, doesn't idle well,or makes any perceptible pinging noise,just jump up to the higher octane rating.Most all we ever used in stock Polaris engines was 87 octane. Every machine is a little different along with where it's used,altitude,temperature,any mods.

 

Sounds good. Maybe I'll just get the premium U joint grease and use it on everything. Like you say I think it just has the moly and is a little more expensive.

I'll try the 87. I can't imagine it would run poor as the manual says it is ok. Thanks again.
