2019 Ford Explorer engine problems

Filed Sep 3, 2026 · Engine · SC

The internal timing-chain-driven water pump on my 2019 Ford Explorer Sport 3.5L EcoBoost is failing. I began experiencing coolant loss and the cabin heat would turn cold while the vehicle was stopped or idling. The vehicle was professionally inspected by an independent repair facility. After diagnostic testing, the mechanic confirmed coolant leaking from the water pump weep hole and diagnosed a failing internal water pump. The water pump is located inside the engine and is driven by the timing chain. Continued failure can result in significant coolant loss, overheating, coolant entering the engine oil, and potentially severe engine damage or engine failure while driving. I am concerned about the safety risk of an unexpected loss of engine operation. The vehicle did not initially display an overheating warning despite the coolant loss and heating symptoms. The failure has been confirmed by a professional mechanic and documentation/photos of the leak and diagnosis are available upon request. Replacement requires extensive engine/timing-system disassembly and I was quoted several thousand dollars for the repair. I am requesting that the federal safety agency investigate internal water pump failures involving the 3.5L engine used in these Ford Explorer vehicles.
