Making 300 mile round trip tonight. I have a coolant bottle cap gasket leaking(slight tricle at Operating temps). Upon inspection gasket seems warped/distorted. Auto Zone has the Stant replacement but it does not click when it is tightened to spec like the O.E.M.. It just tightens down with no click, click click. Are these any good, has anyone tried them. Does it make a difference when it tightens if it clicks or not. As long as it seals right? Need to make a decision fast. Leaving in an hour.

 

The OEM is pressure regulated when it goes click click. it will allow a maximum of 18psi in the cooling system and starts letting pressure off at 16psi
