Which One Do You think actually gets the Job Done? I wonder if the Original Skirt ever Did Do, a very good Job??
The Old Skirt You are looking at...I pried-off of the Original Robertshaw Thermostat, that came with-in the Cleveland Engine of My '74 Pantera. It is 45 Years Old and a Testament to the Longevity of Copper with-in the Caustic Environment of the Cleveland Cooling System.
It came off with out much force. The Skirts I install are Mounted, with a Technique, so as to Never Come Loose, Never Come Off!
