I bought a 2007 prowler 650h1 recently with 95hrs and 182 miles on it. Has lots of accessories......roof, heavy glass windsheild, doors with removeable windows and back window, box heater on the floor, turn signals, winch, 72" Curtis plow. Nice looking machine. Well......haven't taken it out yet as I'm working on a trailer for it but I noticed it overheating........some fluid was leaking out.......both thru the radiator tube and near engine somewhere. Fan doesnt kick on, fuse is good. I tightened all hoses etc as the old timer i bought it from told me he had once noticed a leak on one of the added heater hoses. I added some fluid but she still overheats.....pushing antifreeze out the radiator .......I pulled the thermostat.......it opens in boiling water......fan doesn't turn on.......but I notice no water flow with thermostat out. Is my water pump out?? Could there be air in the system stopping flow? I need some advice as Im not sure what to do......I ordered new thermostat and both sensors so I know I can eliminate those but I'm not sure how to figure water pump and/or air lock issue.
