radiator choise/install (Page 1/1) thelinsells JUN 24, 12:59 PM whats a good replacement radiator,and what do I need to know to do it? sleek fiero JUN 24, 02:21 PM I changed mine out for a champion 3 core aluminum . It fit Nicley and cools just fine. Installation is pretty easy with just a few handtools . I had to find some rubber foam material to seal around the edges as my original foam had deteriorated . I found new heat resistant foam at my hardware store as they sell it for window air conditioners. Biggest obstacle is going through the bleeding procedure to get any air trapped in the system.
