In February of this year the original factory radiator on my 04 renegade developed a pin sized hole on the front upper driver side. i bought a new one and finished the swap in 2 hours with no problems. since then i have had the same sized hole pop up in the same exact location on 3 more brand new radiators. at this rate im swapping a radiator every 6 weeks. has anyone else had this problem? any recommendations?
