- 2018 Ford Explorer XLT
I tracked down the part #s and service cut-in dates for the latest parts and found that Ford used the same AT4Z-8501-B water pump from 2 JAN 2012 and newer. Doing Google searching, a lot of the water pump failures were related to pre-2012 engines. Has anyone with a 2013 or newer Explorer (or Taurus/MKS/Flex/etc...) experienced water pump failures?
For the PTU, Ford had several different parts. One for N/A w/o Cooler (DT4Z-7251-G) and it seemed to be for 15 JUN 2016 and newer. I recall one of the police fleet maintainers here saying Ford cut-in a change to the internal gears in June 2016 for the PTUs to prevent the idler gears from walking into the case (which I assume overheats the fluid). It still seems early to see if there are any 2017 Explorers with PTU failures but so far I haven't heard of any. I have heard of 2015 and 2016 Explorers with PTU failures.
The other PTU is for turbo with cooler, DG1Z-7251-F, which had more confusing cut-in service dates, it seemed like it was used only up to JAN 2016, but I can't find one for 2016-up.
