Is there a way to evacuate air from a slant six cooling system?

I think it's normal too. The gauges in our cars are not perfectly accurate, so it's probably opening at 195 the way it's supposed to. The temp. maybe climbs up a little and then settles at 195. Check your hoses and make sure nothing is collapsing. Maybe the thermostat is not functioning just right. But again, I don't think you have any problems
