No torches, too much plastic under the hood.. I think I'll end up making a tool. Use a torch, heat up a length of plastic pipe, use a screwdriver to push out some grooves so maybe it'll fit over the cap and grab the ridges. I have to wait for time to fool with it. Good thing today is (8/13/20) temps are back to 'normal" for summer in NJ and a/c works fine when ambient temps are below 90F .
