Dont bet on returning a leaking radiator. They dont answer phones, reply to texts or e-mails. Your going to be stuck buying another radiator. I bough an all aluminum heavy duty radiator, it leaked less than a year later. Had to buy another radiator at full price from these guys to get back on the road. Been trying for several weeks . Finally got someone while typing this, but they opened over an hour late from their posted time. They are asking for more pictures after I already sent in January and now its boxed up which was a pain.
