Update by user Dec 10, 2020 Several emails were sent a year ago about the original failure. I sent a recent email asking for help and here is my reply.I am very sorry to hear about your trouble with the item you purchased.Unfortunately we are not a retail facility and we cant help you, in addition Rock Auto is not an authorized DENSO retailer. My apologies for not being able to assist you, Avi MeronSenior Service Engineer Original review posted by user Dec 10, 2020 Denso will not help with the second replacement radiator since it's a few weeks over the 1 year warranty. MADE IN CHINA no longer a JAPAN product with a bad warranty and quality even though it cost more then the competitors lifetime radiators. User's recommendation: Denso no longer manufactures quality parts.
