== == No pressure means a leak (Internal or External) or a bad radiator cap. Try the radiator cap first as it is the easiest to replace. If pressure still fails to build, inspect your system carefully. Look for ANY evidence of moisture on engine components and try to find the leaking gasket. Also be aware that some gaskets can give way inside your engine releasing pressure/ antifreeze into your Combustion chambers and/ or oil reservoirs causing irreparable damage.
