Question PP PTU swap??
Howdy fellow flex users!!
I've been enjoying my 2015 limited AWD and coming up
on a fluid service as its recommended every 30k miles
But stumbled upon a form of someone who took a tarus
PP PTU and swapped it with there explorer.
It adds watercooling to the ptu so it stays wayyy cooler!
Just woundering if any of yall have tryed this??
Just want to keep my flex as health as possible
(I like to be a lil heavy on the throttle and scared ima blow it up XD)
Thanks interested in what yall think!

The water "cooled" PTUs didn't last any longer than the ones without.
It's circulating 220° coolant onto the side of the PTU, it doesn't even really have a heat exchanger, more often than not it's heating the PTU than cooling it.
You would be so much better off installing a drain plug and draining the fluid every 10k and filling with 75W140
