Chipster Posted October 18, 2025 Report Share Posted October 18, 2025 As the owner of a 2016 Edge powered by the 3.5 engine and made aware of the Achilles heel (internal water pump) that this engine has few years before I bought mine, but was not aware of the scope of this issue. One of the aspects of this issue that I am very interested in is what sort of mileage / time did you owners have on theirs when the problem showed itself? One other question is how proactive with preventive measures (reg. oil changes & coolant flushes) were you? When the pump took a crap, did you catch it before your motor was trashed, and if not, did you put another motor in, or was yours re-buildable? What sort of cost was involved in making your Edge “right” whether from a total failure or just replacing the pump with the other associated parts?

enigma-2 Posted 22 hours ago Report Share Posted 22 hours ago From what I've read, most failures were related to lack of maintenance (not changing the coolant or oil changes properly.) I plan on having mine changed at around 175k. (My 2009 3.5L MKX currently has around 144k.) My mechanic drops the engine, and changes everything that fails when he does water pump. Not just the water pump, thermostat, timing, but camshaft phasers as well. 1 Quote Link to comment Share on other sites More sharing options...
