So I knew that my Bronco was somewhere near the hot zone for the 2.7L engine failures but I kept avoiding checking it. I finally did this week and I'm smack in the middle of the worst date... My date code is 21168 June 17th.

But it's still going strong with 10,681 miles. I'm curious who has the most miles with a Hot Zone engine? I see that most blown engines have 7500 miles or less. Does this mean we are out of the woods? I have some long distance trips planned and I'm worried a bit.

I bought my Bronco in August. I have no idea what my engine number is (or whatever), but I have 16000k worry-free miles. I'm really looking forward to a tiny commute this year, so I expect to put very few on this year!

July 12th, I think

23,000 miles

Don't know if it makes a difference but my engine sticker says RWD.

That is so much work to open my hood and look. :LOL: It's like 93 degrees with 90% humidity here. Is it supposed to be those numbers that are circled, or is it an example?

An example. 21 is the year code (2021) and the next 3 numbers are the Julian date code. That means the number of the day of the year your truck was built. Jan 01 would be 21001. Mine was built on June 17, it's code 21168 or the 168th day of 2021.

And it's been 100 degrees all last week here in NJ when I checked under my hood lol. It was a really nice 85 today, low 70s in the morning.
