If you can get your hands on the owners manual it should tell you. At best I think they might change the coolant and maybe the trans fluid. There is also an injector service that they do. If you don't have a warranty, then don't sweat it too much. Plus you may have just voided warranty anyway. Just have the shop that did your bulletproofing do those things if you feel the need.
