Why did Ford put the water pump inside the engine?

Why Ford Put the Water Pump Inside the Engine
Ford put the water pump inside the engine for several reasons. One of the primary benefits is improved engine cooling efficiency, as the pump’s internal placement allows for a more direct flow of coolant within the engine, ensuring optimal heat transfer. This innovative design is particularly notable in Ford’s EcoBoost engine lineup, which incorporates this advanced cooling system design. However, this design has faced criticism and legal issues, with some customers expressing frustration over the placement of the water pump inside the engine and the associated repair costs [[10]].
The internal placement of the water pump, powered by an internal chain, has led to concerns about the cost and complexity of repairs, as well as the potential for coolant and oil to mix if the pump fails. This has resulted in class-action lawsuits and legal disputes over the design and associated repair expenses.
While the internal placement of the water pump offers certain advantages in terms of cooling efficiency, it has also led to significant challenges for some Ford vehicle owners, particularly in terms of repair costs and potential engine damage if the pump fails [[10]].
