I have a sportsman 600 that this winter while plowing I noticed was doggie so I was gonna do a tune up and when I went to change the air filter the air box had about 1/2 inch of coolant in it I cleaned it all out and went about my way checked It the other day and there is about an 1/8th on there again I watched as it ran and is seems to come from the breather line from the head/valve cover. What could cause coolant and yes its coolant it is sweet to taste.
Fuel Pump Replacement
Our 2015 570 Touring with about 300 hours showed symptoms of fuel problems last fall when in the mountains but I mistook it for moisture problems after fording a deep creek. Then it started to backfire occasionally. It was shortly after that it got put away for the winter. This spring I could get it started easily, but it would not run for more than a few seconds after the choke opened. It would only run up to around 3000 rpm and labored heavily to get there. Absolutely no way I could get on and ride. Classic fuel starvation. Pumped out the old fuel and filled with new. No difference. Took the 570 apart and tested the fuel pump. It was delivering only about 28 psi of pressure to the motor so replacement was indicated. Ordered a kit from Quantum Fuel Systems in CA and had it in four days. The kit restored proper pressure of 58 psi and it is now running like new. It included a new pump, filter, wires, o-rings, and locking ring seal. No fuel regulator.
Glad to have it running so well again. It has had this declining pressure problem for a while but I never noticed it until it got really poor. It was a good excuse to buy a fuel pressure gauge kit and was also a good exercise in disassembling the plastic body parts. Now I won't fight with them when working on other components!
Saved hundreds of dollars versus taking it in to Polaris for repair. Cost me about 80 bucks including shipping. I also bought a pack of pump filters -- I now know to replace them at least once a year or two, depending on usage. The only trouble was getting the pump assembly locking ring loose. I bought a tool that straddled the ring and worked, but just barely fit so I had to work extremely slowly because it was jammed up against the steering housing. If you need to do this yourself get the lock ring pliers like the guy uses in the youtube video.
The o-ring that the pump motor presses against was mis-shaped and probably the source of the problem, but I replaced the motor anyway since the replacement seemed more robust. I hope these parts remain available for years to come. I did solder the motor to the factory wires even though the kit came with wires pre-soldered and clips for attachment to existing. Just seemed quick and easy to me. Getting the tank lock ring reinstalled was almost as much of a pain as taking it off, and I soon tired of not having those aforementioned pliers.
I wish to express my thanks to those on this site for posting their experiences and advice, along with those that take the time to video their repairs and help the hordes of us that need someone to hold our hand through the process. You folks rock!!!

Broken Shaft
I am unsure of the name of the shaft but its the shaft that the oil seal, water pump mechanical and impellar sit on. I have had major issues with a leak since i bought it and when i went to replace the water pump seal i found that the shaft was already broke between the water pump mechanical and the oil seal. So anyone know the name of the part I need to track down to fix this and how difficult is this to replace yourself? I assume it will involve removing the engine? I have a 2002 polaris sportsman 400. Anyone with any advice I would appreciate. I live far in the woods so traveling for repairs would be costly and time consuming. Thanks for the help.
04 trailblazer issues
So last weekend i got an 04 trailblazer ran great, owner had just haf it rebuilt, ive started it a couple times and drove it up my street and it started within 3 pulls everytime. This morning i took it iyt and rode four miles and slowed down at a T in the road. It has an idle issue and dies if tou ket off the throttle. It died cause i let off so i went to start it and after 20 pulls or more it fired and rook a few more tries but i got it running again. I rode it fine back to the truck and let off to cross a road and ot died again this time I can not get it started. Im hoping its a simple fix but im betting it lost compression. Is there anything else i should check on before i tear into a motor rebuild?

Trailblazer axel
Hi everyone! I have a 2004 (I believe) trailblazer. I replace the rear axel housing with no problem. The retaining clip on the right side was loose so I took off the right tire, got the clip off. Now i put it back together and there are splines showing!!! So the clip doesn’t get close enough to the chain and other stuff. What happened???
Polaris magnum 425 low power
Hello,
I'm new to the forum. I recently bought a 98 magnum 425. It runs and drives good but feel it's lacking power. In high gear it only goes 25 mph on a good day. It'll crawl up anything in low but still not very fast The machine is new to me so I'm not sure if that's normal? I installed a new belt and changed fluids. Maybe the drive clutch is worn? Engine doesn't bog down just doesn't seem to have enough power.

can you guys provide insight on a few problems im having?
hey guys, i ride my 570 fairly hard (same way i rode my previous hondas) and im having a couple really annoying issues
1. my steering (not an eps model) has developed a LOUD squeak that no amount of WD40 or oil seems to be able to fix
2. at around 60kmh/35mph i get a wicked shake, tried balancing beads they were no help. stock wheels or aftermarket wheels/tires doesnt seem to matter
starting to really regret going to an American OEM again, this thing is getting beyond frustrating at this point

One sided trouble.
Hey guys and gals. Having a little issue with my 2011 Sportsman 800. I bought new tires last week. 12x9x27’s. Everything fits except for the right front (if you’re looking at the bike). For some reason the right front tire rubs the tie rod end. I pulled the front wheels off, did a realignment, put them back on...same problem. I checked my ball joints, decided they were a little loose, so I changed them this evening. Put the tires back on and that tire is still rubbing. I have about 3/4” clearance on the left tire but the right one is right up against the tie rod. Any suggestions what could be causing the problem?
2016 sportsman 850xp
I just purchased a 2016 polaris sportsman 850xp I ordered a oil change kit with ps-4 oil and I'm wondering whats recommended through polaris for front diff,transmission fluid and rear diff fluid I want to use all polaris brands just making sure I use the correct fluids for each one cause the atv didn't come with owners manual and I know the front diff takes a special fluid as for the trans and rear diff
2012 Sportsman 500 HO won’t start
Ran fine then one morning would not start. Engine turns over fine, gets spark will not fire up. Changed fuel filter and filter, new spark plug, checked all fuel lines...all clear. It will fire up for a short time if I put fuel directly into the carb. What is the probability this Is an electrical problem or some other mechanical issue?
