My BX2200 was running hot. After mowing for a half hour the needle goes into the red zone. It was suggested I install a new thermostat. I did so. After warming up. Water and Steam busted out from the gasket! I did this repair twice! I used the paper gasket with "PERMATEX 2 FORM A GASKET SEALANT" on both sides of the paper gasket. The label also says "NON HARDENING PLIABLE SEALANT" Wrong Product? Something else? --- Thanks
