Worked well on my 2000 Chrysler Town and Country, helped me find small leak in Radiator. I would recommend it to any tech that services multiple makes / models.
Will this work on semi trucks I don’t know the diameter of the radiator filler neck on a semi truck, if it is standard size like a car or full size truck, it will. Where is this made? Taiwan Does it work for 2001 Toyota Celica GTS? Not sure, all depending of the diameter of the neck, and if the trad on the neck is in the outside. I have use this tool in GM cars with that type of reservoir, and work's fine. I did look a picture of the reservoir on line and looks like it will work. Is this the good otc or the stinger bs? Its a OTC. Been using it as a professional truck Master Technician for years. Just read the instructions and you won't get a bath. Works very well. Any reasons to expect this will not work on a 2006 BMW 325xi ( AST tool# BMW 350 ) none
