my 13 600 pro went down last winter, and I don't know what caused it. we unloaded off the trailer and drove a really rough ditch for about 1 mile. slow speeds, scratchers probably were not doing much, but it was slow going on real easy on the throttle. we got off the 1 mile rough ditch and drove another 1-2 miles on trail and the engine gets boggy for about 5 seconds and stops. I go to pull the rope and its locked up.
I let it cool off for 10 minutes and now I can pull the rope. I pull it, get the gauge lit up, toggle to the engine temp display, and I show 180. I take it in the trees, trench around, and watch the temp to down to 125-130. it ran good, had normal power, etc... drove it that whole day without it skipping a beat.
day 2 - we unload at a different spot and drive down a trail. it is warm out (spring riding), but I was watching my temp gauge. it stayed around 125 for the first few miles, so I stopped staring at it. about 5 miles down the trail it bogs down and dies. pull rope is tight, engine is tight. I let it cool down for, pull the rope, and it starts. it started hard, but it started. temp gauge showed in that 180 range again.
I decided I better load the sled up and figure out whats wrong with it. we headed back to the trailer. this time I had a noticeable loss of power, but it still ran good enough for me to say "screw it, ill make it back". well, I got about few miles and it progressively started getting worse and worse. the engine was really working to maintain speed on the trail. im sure the bad cylinder was loosing compression.
we decided to tow it back the rest of the way. it will still start and run, but it sounds like it is running on 1 cylinder (obviously). so what are the possible causes for this? I know I can take it apart and fix it, but I don't get what caused it.
is 180 the point these will lock up due to thermal expansion?
I have proper coolant level. I use good scratchers. I have driven this same sled in worse conditions and never had cooling issues unless driving real slow.
