If you have ever tried to remove one that has been installed on a car that has sat in storage for many years you would not put one on your car. They get corroded and will not unscrew so you can take them apart. If they will not unscrew you will damage your radiator neck getting the thing off. If you have an old radiator it is OK but I would not use it on a new radiator. If you just have to have one use lots of anti seize on the threeds.
