I just had my engine replaced, because I didn't change my timing belt. I was going to eventually replace it but never got to it and I paid for it. That is engine lasted over 360K miles. I replaced it with an engine with 75K miles on it. I need to know what year the engine was built. The casting number is 4302042/F22A1. Thanks.

 

does it have a VIN on the back, that will make it easier

 

Here is what Ive heard...

Take the first digit of the engine serial number (4 in your case).

Yourengine was originally installed in the 4th model-year for that engine. So now we have tofigure out what year was the first year the F22A1 was used. Anyone know??

A crate engine (say you bought a NEW engine from your dealer parts department)... would have zero as the first digit.

 

F22A was used in the Accord and the Prelude S, but the version with the A1 head was only in the Accord. I am pretty sure it was introduced in the 4th gen Accord (1990), but it could've been in the earlier 3rd gen (1986-89).
