I know this sounds ignorant (and there are many variables) but what would be a “normal” or acceptable water temp running at 70 mph at an outside air temp of 85-90 degrees? I’m running a 180 degree thermostat and I’m showing between 192 and 200 degrees. (With The AC on it kicks it up around 3 degrees). It gets hotter at stop lights (approaching boiling if it a real long light and hot outside) which I’m able to bring it down by putting it into neutral and increasing the rpm a little. Is all of this normal or indicative of a weak cooling system.
