wil it take the value of my car away. i have a feature car and dont wana screw up what i have.:bigthumbsupI just put one in mine, it's just an expansion tank but it's not leak prone like the plastic jug is, plus it looks a lot better than an ugly yellowed plastic one. That alone makes it worth getting, to me. It accepts the stock coolant sensor assembly, and can be polished for extra bling under the hood. Pictures of it in my gallery.
