Blue point by snap on cooling system pressure tester. Another quality used vintage piece from my collection. Something else that I will probably never use again. Been in my toolbox many years and probably more suited to older vehicles with a proper rad cap. I did try to use it a while ago on an Audi and couldn’t get it to fit or pump the system effectively so gave up. I’m not sure if it was me or the pump piece at fault so please bear this in mind as I don’t want any moaning pricks whinging after they have bought something for a bargain price. Hopefully it works for you for many more years
