Review on Stant 12033 Threaded Radiator Adapter by Scott Ramu

Worked well. I like the old school Stant coolant pressure tester. I find them more reliable than most other systems and also easier to use. Amazing instruments, well made and durable! ***UPDATE*** 8-3-17 Still in excellent condition. I still use it from time to time at some GMs. I prefer to work with older cars than later models (pre 2008 and all before). My original instrument is still holding up just as well and is at least 30 years old. Hope the adapters last that long!
