The last few weeks I've noticed the temperature gauge rising. We checked the radiator, and it looked foamy. As I drive with the heater on, sometimes it's warm and other times it's cool. One day the temperature gauge rose to 3/4 and only stayed stable when I had it on cruise. We attempted to flush the radiator, and it was a cedar brown, thick, foamy color. We thinned it out but assume it needs a pressure flush. There doesn't seem to be any water in the oil, it looks normal. As we were flushing it, the temperature gauge stayed at the normal rate. Wondering if it could be a thermostat or more serious issues?
