I've noticed some seepage from my Lucerne radiator cap so I got a new GM replacement and am going to change it, Question, there is a white dot on the cap and I recall seeing something (somewhere) about making sure the dot is lined up with the overflow resevoir hose. The owner manual only mentions lining up an arrow (and there are none) so I'm guessing its a mis-print. Does anybody know if the alignment of the dot on the cap is important?
