My BX24 started to spray antifreeze around the top hose right above the thermostat. So I replaced the thermostat, hose, clamp and gasket. I thought I had it licked, I was using the machine today to do some snow removal and I started to smell that sweet smell when antifreeze hits hot exhaust. I opened the hood and saw drips on the hose and the top of engine and hood. Not sure what else to do or even try. Any help would be appreciated.
