READ ALL FIRST!!!!! ALL SALES FINAL, NO RETURNS OR REFUNDS FOR PARTS OR FIX ONLY !!!!!!!!!LEAKS!!!!!!!!!!!!!!!!! FROM A 2002 CHEVY EXPRESS 2500 VAN THE METAL IS ok AND NEVER HAD ANY LEAKS IN METAL, BUT THE PLASTIC ON ONE SIDE HAS A LONG CRACK IN THE CENTER OF THE PLASTIC. I TRIED VARIOUS PATCH KITS, SCRAPING OUT/WIDENING THE CRACK PER INSTRUCTIONS, AND USING JB WELD RADIATOR REPAIR KITS. ZOOM IN ON PHOTOS TO SEE. STILL LEAKS, THE GREY PATCHES SEEMED TO HOLD BUT THE LARGER BLACK ONES DID NOT. I GAVE UP AND BOUGHT A NEW RADIATOR, MAYBE YOU HAVE MORE EXPERIENCE OR CAN REPLACE THE PLASTIC SIDES ON THE METAL RADIATOR?. THE DARK AREA IS WHERE WE SPILLED TRANNY FLUID AND IT SOAKED ONTO IT, IT IS NOT A DEFECT NOR A LEAK. YOU CAN CLEAN OFF WITH ENGINE CLEANER. BOX SHOWN IS THE NEW NAPA ONE WE BOUGHT TO REPLACE THE ONE FOR SALE. SHOWING SO YOU CAN VERIFY THE MODEL. THE RADIATOR FOR SALE IS PROBABLY THE OEM ORIGINAL AND NOT A NAPA, WE DO NOT KNOW, BUT LOOKED TO HAVE NEVER BEEN REPLACED, WE BOUGHT THE VAN 2ND HAND, SO TO CLARIFY IT IS PROBABLY NOT A NAPA RADIATOR SELLING AS YOU SEE IT FOR PARTS OR FIX ONLY, NO RETURNS NO REFUNDS WILL SHIP IN BOX SHOWN, BOX IS A LITTLE BEAT UP BUT WILL TAPE IT UP WELL.
