I have a very slight coolant drip from the one of the hose clamps connecting the top stainless steel flexible radiator hose to the suge tank (351W) on the tank end. Hose clamps are tightened as much as I feel comfortable with. I've replaced the 13psi cap on the tank and removed the cap altogether from my overflow tank, but excessive pressure seems to be building up. Next step will be to drain radiator down halfway to allow removal and reattachment of top radiator hose. Before doing that, I was wondering what the pressure rating on the tank cap should be. Is 13psi about right or should I be using one with a lower pressure rating?
