Have a 2011 polaris 6x6 800 that overheats every time I use it. The coolant will come out the over flow.
The most common causes of a water cooled engine overheating are (1) poor circulation of cooling fluid (bad water pump or stopped up radiator); or (2) inadequate air flow cooling (bad cooling fan); or (3) compression gases entering the cooling system (leaking head gasket or cracked block or head). The first check is to see if air is in the cooling fluid (small bubbles appearing in top of radiator or coolant reserve tank). If so, then #3 is the problem. The second check is to see if the cooling fan (s) is running properly (can feel air flow on output side?). If not check wiring and/or replace fan (#2). The last step is to drain the radiator and engine (turn over engine to allow water pump to empty the block). If additional cooling fluid does not drain out the radiator drain port, the water pump is defective. If the water pump does empty the block, then flush the system with a good flushing agent. Follow instructions on flushing agent bottle. Drain out the flushing agent and re-fill radiator and block with clear water. Run engine as per instructions on flush agent bottle. Drain system again and re-fill with antifreeze (50%) and water (50%). If vehicle is located in a very cold climate, then increase the antifreeze % up to 75% (25% water). Remember, not only does antifreeze help to keep water from freezing, but it also helps to increase cooling ability.

2001 500 HO is stuck in High Forward gear
If the shocks are worn out, get off the machine and lift up on the back rack. This takes up the slop between the shifter box and the transmission, and usually allows me to shift. I also had an issue with the thin steel plate behind the shifter box. Got a crack in the top , so it was flexing, creating more slop. Welded it shut, good as new.
