I wonder if tightening all clamps and such would make a difference. Don't things shrink during cold temps? And expand during hot? One solution I've thought of is to use BOTH the spring clamp and screw tight hose clamp next time I do coolant servicing. I'm wondering if the spring clamps would naturally tighten when colder temperatures cause shrinkage. I have both types of clamps on my expansion tank. Redundant? I wonder? Anyone know if this would make a difference?
