Re: 203 Degree Thermostat??
By increasing the temp of the coolant, usually the engine efficentcy is increased, the old engines used to run 160's now they are up to 240's...
It makes sense to me..I haven't done any testing on mine yet..
as others have observed the increased heat through the heater is great though.
