Applications
Water pump issues
Water pumps on transversely mounted 3.5L V6, 3.5L EcoBoost V6, and 3.7L V6 engines have a tendency to fail and potentially ruin the engine when they do. The water pumps on these engines are internally mounted and driven by the timing chain. As a result, when they fail, antifreeze is dumped directly into the crankcase; mixing with engine oil and potentially damaging the head gaskets and connecting rod bearings. Many of these water pump failures occur without warning and repairs often cost thousands of dollars as the engine needs to be disassembled or removed from the vehicle to access the water pump. In some cases, the engine will need to be replaced outright. A class action lawsuit was started against Ford as a result of this issue, but it was dismissed and no recall was given.
All longitudinally mounted versions of the 3.3, 3.5, 3.5 EcoBoost, and 3.7 V6 use an external water pump.
