2019 Ford Explorer: engine overheating

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.

For months, almost a year, my transmission could not properly accelorate. The car would not allow for the pick up in speed to happen. Each time I took it to the shop that cares for my car, Mike's More Miles, the problem would not duplicate. My special needs son, his service dog and I were all of the expressway traveling, the car slowed down on its own, I had not applied the brakes, the speed dropped from 65 to less than 35 in seconds. I pulled over and tried to regain speed after putting the car into park. No luck. the car would not go faster then 20-30 miles an hour, with me putting into neutral when coasting downhill, then back into drive manually to get it to the repair shop. This almost caused a terrible accident. This scared my son, who has brain disease. Our 85 lb. service dog was jolted from the back of the car slamming into the seat. I was also very scared and shaken. My son began to yell and scream what is happening, it was a scary and tense, literally jaw dropping experience. I drove to Enterprise Rental, called Austin the owner of the shop that has tried to duplicate the problem on a dozen tried and told him what occurred. I left my car at Enterprise, where Austin picked it up. The problem did duplicate. FINALLY a code came up to diagnose the problem. The transmission fluid was also black, with metal shavings in it as well. Please refer to all technical service bulletins that note this is a known problem by Ford. I have paid $7582.70 for a new transmission. The shop owner, Austin, told me the torque converter overheated, the transmission had failed. I also paid for the rental car an estimate of $490.00.
