What is the difference between a 2.0L motor made before 05/31/2011 and a motor made after 06/01/2011? I'm trying to buy a used motor and this question keeps popping up. The production date is on the door sticker.
Edit: an option of before 05/31/11 or after 06/01/11 is required for compatibility, but the engines look identical in side by side pictures. Help..?

There should be a build date on the valve cover.

Ask whoever says that there is a difference what it is and how they can identify each engine , they should know if that is the case . According to this they are no changes


Ford Focus (third generation)

Engine lineup in North America[edit]
The Focus was launched with only one engine option, a 2.0-litre Duratec 20 direct injected, Ti-VCT 4-cylinder, producing 160 hp (119 kW). Mid-2012, Flex Fuel capability was added,[21] except for states in the United States that adhere to partial zero-emissions vehicle regulations. The engine is a derivative of the port fuel-injected 2.0-liter engine in the previous generation Focus.[22] In late 2012, the range was joined by the Focus ST, with a turbocharged 2.0-litre producing 252 hp (188 kW) (available only with a manual transmission).

For the 2015 refresh, the EcoBoost 1.0-litre three-cylinder began to be offered in North America as an extra-cost option for SE trim level. The 2016 model added 2.3-litre EcoBoost for the new RS trim level.

I've called and asked several people, and all they can tell me is that a car with an engine built before 5/31/11 isnt compatible with the same year model car with an engine built after 6/01/11. That's why I'm asking Ford Forums. I need to know why it isn't compatible and what's different between the two.

Who are these people you have called ? Again , whoever says that there is a difference what is it and how they can identify each engine , they should know if that is the case . Let us know if you find out

I called a rep at LKQ (which is where I bought the motor), the service department at the Ford place in my town, and I asked a couple of mechanics when I was calling about labor prices. l bought an engine that was built "before 05/31/11" without realizing it, and I don't see any physical difference; connectors, bolt holes, part attachment places, etc. They say that I can't use that motor, but the only reason they can give me is because that sticker on the car says a different date range than the motor. Is it not compatible with the computer? Did the manufacturers change something in the design halfway through the year? Was it defective? I want to know... I turned to Google, but I couldn't find exactly what I was looking for.

 

[R.S.LOGAN]

The people you spoke with should have been able to tell you why it would not fit or what was needed to make it do so , not just blame or accept a sticker on the car that says a different date range than the motor. , I have dealt with many breaker yards , engine remanufacturers / rebuilders and they all knew their stuff in the compatibility of parts and fitment and would tell you why / why not they were unsuitable . In your post title you list it as a 2012 Ford Focus , why cant you get them to change your engine for the correct year instead of fitting a 2011 and save all the uncertainty ?

 

[85ltdcrownvic]

I’m willing to bet they’re all just saying that to cover themselves. I agree, see if you can get an earlier engine.

 

[R.S.LOGAN]

Did you order the wrong year of engine or did they supply the " wrong " engine ?
