Let the system hold for 20 seconds to observe for a drop in vacuum. CAUTION  A drop in the gauge reading within 20 seconds indicates a vacuum leak in the system, which will require locating and rectifying the leakage before proceeding further. NOTE  During this procedure the radiator hoses will collapse under the vacuum being generated - this is normal.
