My coolent level in my 94 Corolla seems to have gone down ever so slightly, but I have no outward signs of a headgasket leak or an external coolent leak. Is it normal to continually lose a slight bit of coolent from evaporation at the overflow blowoff tube? That seems to be the only spot that is truely open to the atmosphere in a closed cooling system. Also, the level has dropped since the weather has started to cool off in the fall. IE, when I check the level in the mornings in my garage, the temperatue in there has probably been 10-15 degrees cooler when I check it than during the summer months. Would the coolent level be affected that much by decreasing ambient temps like that? Thanks guys.
