This is Why the Ford 1.5L 1.6L 2.0L and 2.3L Ecoboost Engines are Gulping Coolant!

Two things amaze me here: 1. The engineers actually thought that block with the slit was a good idea. 2. That poor design actually worked at all for any period of time.

We have had 3 major engine repairs (all for this issue) with our 2018 Escape BEFORE 30K miles. I think it has the 1.5L engine. I cannot imagine how much this has cost Ford, but I do know it has cost them a customer. Thank you for explaining it much better than our service advisors.

I'm a tech at a Toyota dealer. A while ago we sold a used 17 Lincoln MKC with the 2.0 and it came back to us over the summer with this exact issue at around 125k. Hearing that they updated the engine makes me very glad that we sourced a fresh long block from the Ford dealer next door rather than getting a used motor. Ironically the long block was cheaper than a used motor, even with adding on a turbo due to coolant in the oil.

I own a 09 Ford Ranger Sport, regular cab, short bed, with the 2.3 ltr. Mazda engine with an automatic. It was was built in the Twin Cities assembly plant just before they shut down. Kudos to the folks that built it. It's still as tight as the day I drove it home from the dealership and now has over a 190,000 miles on it. It's been used and abused and still running strong..Something we may never see again from Ford...

At one point in time I was the record holder at the Ford Dealership I once worked for as a tech, I ended up having 12 Escapes back lined waiting for parts and block too. The process was insane especially when I had to use dollies to achieve this operation at times. These warranty repair orders were a nightmare at first until the process was refined.

love when the bean counters get involved in designing things. it almost always ends poorly

Thank you for your channel and posting the videos that you do. Your videos are great and the comments from viewers are just awesome, which indicates the skill level of the viewers you have attracted. Keep up the good work.

Thanks for the detailed information. A friend of mine has the 1.5 and this happened but she got a quote for a brand new engine instead of a rebuild with a huge price tag.

I guarantee that the engineers at Ford didn't want to do that and some guy wearing a suit and holding a checkbook came and overrode him and here we are...

Chrysler figured out that cross drill idea back in 1988. The engineers supposedly determined that it kept the head gasket about 70 degrees cooler between the cylinders.

The coolant level on my 2013 Fusion Titanium kept dropping every couple of weeks. I would check the oil and inside the engine bay, but could never find a trace of a leak. Well, one night I was driving on the freeway when I heard the loudest pop I had ever heard inside a car. It sounded exactly like a plastic bottle full of air exploding. Turns out that a coolant hose blew up. I was able to make it home and noticed the coolant reservoir was empty. After the hose was replaced, the coolant level remained the same. Although the pop scared the crap out of me that night, I'm glad the coolant wasn't leaking into the engine.

Really appreciate your work. 2k8 Escape Hybrid (thx for the repair vid) 148k miles and 2022 PowerBoost F150 15k miles.

I've seen some videos of the EcoBoost v6 failing in Ford trucks such as F150 and the Expedition, and several Mustangs. Been a loyal Ford buyer for a long time with some Lincolns in the mix as well, all V8s though. No more, switching brands because there is no way any of the Engineers at Ford didn't know about this and the many other issues not mentioned here. Planned obsolescence is more obvious than ever before.

I've been telling people for YEARS to avoid the 1.5 and 1.6 engines. Also the 1.0

Good to know. I have a ‘17 2.0 I bought used, only have around 60k on it. No issues so far, I’ve had it 3 years. Glad I bought an extended drivetrain warranty.

Im impressed you keep your shop so clean.

If the block was two or three inches longer they could have spaced the bores a bit more and put a vertical web between the bores to increase cooling surface area.

Love your videos. They helped me rebuild my old 5.4 after timing chain guides broke

You got me through the dark days of my 5.4 Triton. I became a DIY expert thanks to your tutelage. Some of these engineering decisions are mind boggling. I would venture to bet that top 10 techs on YouTube could design better products based on how many failure points they encounter.

This validated my decision not to buy an Ecoboost Fusion for my wife. At the time I didn't know about the head gaskets blowing out. I just assumed there would be unforeseen problems. She's been very happy with the naturally aspirated 2.5L.
