The 4 cylinder Lincolns make me nervous because so many people have had so much trouble with Ford, and those V6 3.7’s & 3.5’s had the water pump in the engine so those were designed to force expensive repairs at Ford & Lincoln dealerships. Americans really don’t even know about the Ford owners in the UK that went broke after buying the Ford 1.0’s and there was a scandal over there over it and Ford fought the owners tooth & nail for years over it… and all along Ford knew they were at fault. They only gave in after enough time went by, after the life of their 1.0 would have been over.
The 3.5 and 3.7 can actually be very reliable engines, it's just their internal water pump that's their Achilles heel. I've seen plenty with well over 200K miles and some Lincoln MKTs with over 300K miles (used as fleet vehicles). The early 3.5 and 3.7s were the worst because Ford only used a single gasket design for the water pump; beginning around 2010-ish and later they designed the water pump with two gaskets so once coolant penetrated the first gasket it was directed to flow out the weep hole. With the single gasket design the coolant didn't always penetrate precisely where the weep hole was it, it could occur anywhere and leak directly into the engine instead. As for the 2.0 EcoBoost I'm beginning to think our first replacement engine failing before 5K miles is a fluke. Like I say in the video Ford (supposedly) stopped using the blocks with the bad cooling jacket design starting before the 2020 model year. I wish I knew why the replacement failed but I'll probably never will. No one will get back to me on their expertise regarding the issue. I've asked several renounced UA-camrs and none have responded. It's been months and it frustrates me. Interestingly though, when I look at new 2.0 and 2.3 EcoBoosts on relatively new Fords/Lincolns produced after 2020, they have a 6007 block part number. I've never seen a 6006 block (the one that failed before 5K miles) used in a brand-new Ford/Lincoln vehicle; I've only seen them used as replacement engines for 206 blocks like in our MKC. I can't find anything online that a 6007 block is problematic like the 206 and (potentially) 6006, so I'd guess Ford has resolved the issue by now
