worth a shot! i've never actually run without one before, I just wanted to this time as I have all new hoses and a new block heater, and also running just water so that if there was a leak, it wouldn't leak paint killing coolant...

you would think tho, that there would not be much pressure difference with or without a thermostat ???

I dunno I'm at a complete loss...
