The visible coolant level is about an inch below the top of the reservoir. Should the reservoir be full?

If the resevoir has a pressure cap on it and is mounted above the level of the radiator, about 2/3 full when cold is ballpark. If you fill this type to the top, it will just spit it out as it warms up. __________________ 2008 Itasca 37H 2011 & 2012 Len & Pat's "One lap of America" 27K miles & 41 states in 13 months Yellowstone Lake 6-1-2012
