    ATV General Discussion
    Hi all, I appreciate there are some other threads out there on this topic, but looking to maybe get some fresh views. I will admit I am new to Polaris. I have been a Honda guy for years, so trying to learn on the fly about the differences. I recently picked up a 2007 800 EFI with 1500 miles...
  3. 2004 Sportsman 600 venting anti-freeze

    ATV Repair and Maintenance
    So I have a 2004 Sportsman 600 Twin to work around my farm. After I've put a load on the engine dragging logs and such, the ATV will "piss" anti-freeze out the cap. Is that normal? Seems like an easy question to throw out to the forum...

  5. Scrambler 400 coolant issue

    ATV Repair and Maintenance
    I have a question about my 1997 scrambler 400. I recently rebuilt the top end and the coolant reservoir cap sometimes has a little bit of antifreeze on it after riding it. It doesn't shoot out or anything its just there is a little drop on the cap sometimes. It runs fine and I have been riding...

  7. How long can you run with coolant weeping from weep hole?

    ATV Repair and Maintenance
    My 2006 Sportsman 800 is weeping coolant (about one drop per every 3 seconds) from the weep hole. the fluid is very clean without any oil residue. The oil is also without coolant in it. If I maintain correct coolant levels in the reservoir, can I theoretically run it forever? Very...

  11. Water Temp Guage

    Polaris Sportsman
    I was wondering what is the easiest way to put a water temp gauge on a 2000 Sportsman 500? I was thinking just to attach some kind of bolt on my coolant inlet tube and run it to the gauge. Do you think this would work? And also what is the temp that the coolant light turns on at and what is the...

  13. "Newbie" Cooling System Issue

    Polaris Sportsman
    I just got my first ATV so I'm a newbie! I used to run Jeeps but with gas prices an ATV makes more sense. I bought a 2000 Polaris Sportsman 500. It ran fine when I took it for a spin around the guy’s driveway. When I got it home I greased it all up good and took it for a light duty drive...
