So I've been gearing up to start the timing chain job on our 2014 explorer sport with 3.5L eco boost. Working with Ford White Bear Lake and sent them my part numbers list for verification and price quote. According to the gentleman I'm working with, based on the vin I have an older architecture 3.5EB with phasers/solenoids on the intake cam only and, more curiously that it has an external water pump. This is a bit odd to me. I do believe the cam timing gear could be different although I didn't know it was that different. I though all these 3.5s has internal water pumps, though??
