Introduced for 2015, the refreshed Expedition EL replaced the long-serving Triton V8 with Ford’s twin-turbocharged 3.5-litre EcoBoost V6, invigorating the extended full-size platform with 365 hp and 570 Nm of torque. Tailored for hauling maximum passenger loads and hefty trailers across continental distances, proactive Ford Expedition maintenance is crucial to protect forced-induction hardware and heavy-duty running gear. Retaining its 3.32-metre wheelbase and cavernous three-row capacity, this facelifted EL transformed highway responsiveness.
The twin-turbocharged 3.5 EcoBoost pairs seamlessly with the bulletproof 6R80 six-speed automatic gearbox. However, the EcoBoost introduces distinct servicing needs: direct injection and twin turbos place intense shear stress on engine oil, where delayed servicing induces timing chain stretch and 3.5 EcoBoost twin-turbo V6 cam phaser rattle at cold startup. Furthermore, the massive aluminium bodyshell can still exhibit aluminium tailgate galvanic paint blistering, while underside aluminium air conditioning lines remain susceptible to corrosion from wet road grime.
