Ford EcoBoost Coolant Intrusion Issues Detailed By Veteran Tech: Video

A number of Ford EcoBoost engine issues have been outlined in great detail in the past, ranging from carbon buildup to coolant leaks in Ford’s 1.5L I-4 EcoBoost1.6L I-4 EcoBoost, and 2.0L I-4 EcoBoost engines used in a variety of vehicles including the Ford Escape, Ford Fusion, Ford Edge, Lincoln MKC, and Lincoln MKZ, which have in turn prompted some lawsuits. Experienced Ford technician and YouTuber Ford Tech Makuloco covered some of these problems on a customer’s truck last fall, issues that have been further compounded by COVID-19 induced parts shortages, and now he’s back with a more detailed look at Ford EcoBoost coolant intrusion issues on a 2014 Escape equipped with the 1.6L powerplant.

Our resident tech walks us through the process of performing a pressure test on the crossover’s coolant system when he finds an intrusion in cylinder number two, a problem that’s very common with EcoBoost four-cylinder powerplants. Unfortunately, the only real fix is to replace the entire long block with the updated design, or face endless coolant consumption issues, it seems.

The problems typically occur between cylinders two and three, and it doesn’t even take a ton of miles for the issue to surface – this Escape, for example, had just 55,000 miles on the clock when it first started experiencing problems. Initially, the owner brought it in after a low coolant warning, and the tech told him that he would need a new block at some point. One year later, the crossover was throwing overheating codes after running bone dry in terms of coolant.

Unfortunately, replacing the long block on a vehicle like this costs somewhere between $6,000-$8,000, which is obviously a lot of money to sink into something that isn’t worth a lot more than that. But at this point, the engine is so far gone that it’s a necessity, making this particular Escape one heck of a pricey paperweight otherwise.

    How many times are they going to repeat the same story.

    1. Bobby

      Until they get rid of Ford’s new useless CEO. His priority is pleasing the Government instead of focusing on quality and cost.

    2. JDE

      I suppose until everyone knows. this issue was apparently overshadowed by the Triton 5.4 failure, I had not heard of it except on Sport Focuses where he water jacke moves and causes coolant to leak in the cylinder. SO the huge question is what is going to become of the Bronco? the 2.7 has poorly heat treated valves and is failing with less than 20K miles, the Ecoboost 4 might make it to 55K before it starts to show problems. but just past warranty when it needs major replacement costs. The Maverick engines are machined incorrectly and when they spew oil the belly pan and active shutters trap the oil which could cause a fire. Something has got to give and this is going to give Ford a big black aye for many years to come.

    Ford need to step up to the issue, selling off the unneeded scooters and Rivian, this mess is paid for– we don’t need a VEGA —-

    Have a 2018 edge with 2.0 eco boost sucked the cooling system dry at 28K miles. Dealer replaced the engine. Got 36K on it now, hope the new engine does better.

    1. joe

      were you still in warranty or not? Im out of warranty but only 23k miles on my 17 escape 2.0. hoping this is covered out of time warranty

  5. Stanley

    Ford focusing on inefficient EVs instead of quality and practicality. Ford desperately needs to fire this new CEO. Ford is losing lifelong Ford owners because no one likes him.

  6. JL Chicago

    What about the owner taking responsibility? The Escape had a low coolant warning a year before the failure and the owner apparently never bothered to check the coolant again? That’s crazy lazy. Coolant is about the easiest thing to check. Open hood, look at coolant tank, you don’t even have to open it, and see if the coolant is above the min level. And I bet the owner ignored more low coolant warnings and probably ignored the temp gauge as well. Well he or she got what they deserved.

      I have a 2017 escape with 1.5l turbo and it blew up because of a defective design at 108k miles. I kept the coolant level filled up. The fact of the matter is it was a defective design not user error. Nobody should have to keep putting coolant in their new car. You sound laughable. If Ford can’t design an engine that can’t hold its coolant past 10,000 miles as in many of the cases of blown EcoBoost, it has no business making cars at all.

        We have a 2019 Ford Edge Titanium. 3 weeks ago I noticed like a misfire when at a traffic light. I put it in neutral and pushed the accelerator gently for about 30 seconds. No rough running, no smoke from exhaust and NO engine lights on. Next day started it, left my driveway and came back – would not go over 20 mph! Called tow truck who towed to local garage. Received a phone call the next day “you need a new engine”!! REALLY????? We haven’t even put new tires on yet!! 60,000 miles!
        Had it towed to Ford motor the next day and they diagnosed that we needed a new seal and a couple exhaust seals I believe they called the one part an EGR. “Easy fix! Extended warranty will cover. After reading all of these reviews, my plan is to take that Ford that we love so much, to the dealership that is not American motor vehicles and trade that puppy in! I see that Ford motor is not standing behind many many many people that they should be standing behind they are going to get a very bad name! And oh, by the way, it truly is laughable that somebody would go check the coolant on their new vehicle every day crazy crazy crazy people out there!

      Doesn’t really matter because the coolant intrusion is due to a design FLAW with the engine. Read the TSB.

    Has ford done anything to correct this for 2022 ??


    Amazingly I had a similar drawback with a GM aveo 2012, I dared to try a cooling system sealant called “rislone” carried by Autozone developed in New York (domestic); Luckily it worked out but preferably pour the bottle with new coolant (old previously drained).

    1. Donk

      Rislone is a last ditch effort and only use if its drinking moderate amounts..A few ounces over a week isn’t enough. This stuff will seal a leaking head gasket but also coat your radiator. Bypass the radiator after installing for a did work, but only on the coolant side , won’t seal a compression leak into the water jacket.

  9. Connie

    I have a 2017 Ford Escape Titanium 4WD. My check engine light came on in may. Problem with cylinder number 3. Than we noticed loss off coolant. The dealer checked it and I was told to keep driving the vehicle and ad coolant or water as needed. They have to check what they can do. I have the extended 7 year warranty. So far I have no answer. Vehicle is running rough.
