Is this still a problem on the 2020 expedition?

 

The water pump is still inside the engine so I would believe it is the same poorly designed engine of previous years.I wouldn't own such a poorly thought of engine. The class action law suits continue.

 

@raski dude your thinking of the 3.5 and 3.7 in the explorer/flex/edge. Which have an internal water pump since the engine and trans is sideways in the engine bay and dont leave much extra room at all, but I do agree that is still a bad design for those models, they seem to leak less then the external ones but its devastating when it does leak and no one notices.
The 3.5 ecoboost in the F150/Expedition has a external water pump since the engine and trans is straight in the engine bay. The external water pump does seem to leak more then other engines but then again every engine has its weak spots. The main issue with the water pump leaking in the 3.5 ecoboost is the extra labor since you have to remove all the damn turbo air tubes to get to the damn thing, I change around 2.0 hours labor for the 3.5 ecoboost where as I will do a 3.7 mustang for 0.5 hours cause theres no turbo tubes in the way.

 

So, My 2020 Expedition does not appear to have a belt driven water pump ? I see a radiator hose running straight into the front of the engine. Assume the water pump is internal even though the engine is not positioned sideways ? Am I missing something ?

 

The water pump is right under the hose you are talking about. It is rather hard to see because of all the damn turbo air tubes in the way like I said before.
Now I mean if you want to be technical, then yes the water pump is internal, but then again all water pumps are internal. What is meant by internal water pump in the explorer is that the pump is powered by the timing chain and thus entirely inside the engine so when it starts to leak if not caught the coolant will mix with the oil and destroy the engine.

The yellow is everything powered by that belt, the water pump pulley is circled in red.

 

Thanks for the graphic, it is all difficult to see when I raise the hood. Had heard of the issues with the water pump leaking coolant into the engine oil on this engine, but did not know if this issue affected the Expedition or just the sideways mounted 3.5 engines in the Flex, Explorer, Edge where the water pump was run by the timing chains. Was hoping that this was not an issue on the 3.5 engine on my 2020 Expedition.
