I'm amazed!! I bought a new Ranger Raptor in June last year and it has had 4 recalls already, nothing to do with the oil cooler though? Still, I haven't had a recall for a couple of weeks.......It would appear that instances of failures on the newer ones are less frequent if that's any consolation. We (as a community of owners) went through a bad phase where there was a report of failure every week on the 2015-2016 cars. The failure rate has defiantly gone down on the later cars. But not to zero. There appear to be no reports of failure when the same part is being used as an auto transmission cooler on the 10 speed gearbox in any of its applications (Mustang/Ranger/F150/Expedition/Lincoln Navigator etc/GM equivalents). Its my guess that Ford have build many more 10 speed auto F150's than they have build RHD mustangs. I suspect they use the same part elsewhere on other cars in the ford line up too for general cooling duties. They realised the LHD oil cooler wouldn't work on RHD mustangs due to the packaging requirements of the steering rack, so they sourced a cooler already used in Ford to do the job and designed the bespoke oil manifold to mount It out of the way. The cooler is perfectly up to the job when used on a Focus or Ranger or god knows what else. But in the mustang implementation its operating right at the limits of its specification. Flow rates, temperatures, pressure, ambient heat, vibration etc all play a part in the specification of this part. Look at the diagram below. Ford made up a bracket 7B142 in order to mount this existing cooler part onto the 10 speed gearbox just as they did with making a mounting solution for the RHD mustang. This part was not designed SPECIFICALLY for either job. It's a general part that meets a spec. It's probably been around for years and was originally designed for a car long since departed.
