Right Eric. Some folks live (and/or drive) where there is a lot of stress
on the cooling system and might need an override. But I've had two gas and
one diesel Vanagons that never took the needle over the middle of the gauge
unless something was wrong. But then again, I don't live near a mountain
range and I don't haul heavy trailers. For years I thought a little temp
rise on a steep hill was normal, but since replacing my radiator five years
ago, I don't even get that.
