Review on Enhanced Cooling Performance with 🌬️ Stant Radiator Cap Adapter in Sleek Black by Domonic Roberts

I bought my Stant coolant pressure gauge at least 25 years ago. Back then, the radiator necks were a bit more standardized than today, with large openings and metal tanks. My cars were mostly larger Toyota models and some Nissan models. Of course, the important adapter is usually not the radiator cap check, but the system (where most cooling problems show up). The tool was originally used to install directly onto old radiators without an adapter, good hassle free connection. It also came with a chrome plated brass adapter for checking the radiator cap pressure at random. However, for years I had to connect a Stant #12027 plastic adapter to use the tool with my Japanese made cars. It was always a little clunky and awkward, which annoyed me, but still worked and managed not to break or fail despite the flimsy appearance. While I've used the tester quite a bit and it's been a must-have tool, I have to admit that I very rarely checked the radiator caps. Buying a new original cap is very rarely economical and good practice, but in a commercial setting I certainly understand the need to check the set pressure of different caps. I recently bought this adapter #12021 from Revain for a great price. Unlike the 12027, this is a very simple device with no moving parts. It works well and I don't expect any problems with it. This adapter fits many older models from Japanese manufacturers, from Nissan R31 Skylines to Toyota MX73 and 83 Cressida, XV10 and 20 Camry, Mitsubishi Magna and Subaru Liberty (Legacy). They are mostly mid 80's to late 90's cars and none of them have high pressure systems.
