I recently purchased a 750J. It is overheating. Seller said he replaced thermostat a year ago. I changed all filters and oil yesterday. The fan seems to be blowing good. It will blow off a baseball hat if you stand right by it. The radiator looked clean but I blew / washed it out with no improvement. No oil in coolant and no coolant in oil. Machine can idle for hours and not get hot. Just tracking on flat ground will take it to the red on the coolant temp before you travel a half mile. Stopping and idling will slowly cool it down. The seller said he has never had any heating up issues and I believe him. Since it started doing this pretty much right after I got it home he feels bad about it and offered to help with the cost of repairs.
Any ideas?
