I haven't posted a question in a while but Iam in the process replacing my cooling system. I just installed the pi intake, no leaks thanks to all the info everybody here post about the install. Thank you very much. My 2003 cobra water pump from rockauto is on the way. Along with new upper and lower rad hoses. I have already replaced my rad fan two months ago. Stock type could not find mark vii fan for a good price. I replaced my heater hoses and temp sensors with the pi intake. My question is a 99 mustang aluminum radiator replacement. I know there will be install mods to do but how bad. I know there is the cobra radiator upgrade but I can get a mustang radiator for far less. Any advice or ideas will be very much appreciated. Thank you.
