After riding for about an hour, my rhino will start to overheat, spit and sputter and there is a strong smell of gas. If the rhino stalls or is cut off at this point it will not start up again until cool. My fan works fine. I would like advice on this problem. I have been told replace fuel pump, fuel filter, maybe a vapor lock of some kind. This same problem has happened to a couple of friends of mine who also own rhino 450's.

cooling down

i dont know about the other problems but i use 5oz of water wetter in my radiator and my rhino will run for four straight hours and not go over 205 degrees. i installed a temp gauge so i know its accurate. you can buy it at autozone. hope this helps a little

I am no expert on anything motorized, but I have changed my fuel filter twice already in 2 years.
Make sure you put antifreeze directly in the radiator and not just the clear fill bottle. I don't think the radiator always automatically sucks it up when needed. I found that out the hard way last weekend.
