During a discussion late last year with an agent of our local MMC dealers I was told the brief from MMC regarding radiators during the brake recall/swirl pot addition was to replace if leaking at the time or if the vehicle had a history of previous failures (four or more are not unknown). Those that had never failed were to be left untouched
