How the OEM Oil Cooler works, on a 2018 with the 3.5 V6

[Bobs2018ExplorerSport]

In trying to understand the technology of how the factory-installed Engine Oil Cooler works, I've been told by my friend at Ford, as well as discovered through online research, that in the case of the late-model Explorers, coolant is taken out of the circulation path of the lower (cooler) radiator hose, and circulated upwards into an "Engine Oil Cooler" unit, which is a box-like unit that is attached to the side of a different Oil Filter Adaptor... where hot oil is circulated through (as is the coolant), thereby creating a heat-exchange effect. The coolant is then returned back to the lower radiator hose, to continue on its way into the engine.

Hi Bob. I'm not sure if this article will help you. Basically it talks about a transmission cooler but if you scroll down and click on the picture labelled Transmission Cooler and then scroll down to #21, it says the oil cooler works in a similar

Always wondered that myself. Thanks for sharing.
