This may be a silly thing to ask, but how do you know what kind of an engine you have? Like a d17,d16,h22..ect. And what exactly do they mean, thanks! (Btw, I'm retarded when it comes to cars, for the most part, but I'm willing to learn.)

 

Your engine code's stamped on the block. You should be able to see it if you're looking at your engine from the front of the car. Take a peek down and to your left, and you should be able to see it. The first two numbers in your code denote the engine's displacement, while the third one denotes a revision or upgraded version, I believe. I'll use my car as an example. A D16Y8 = 1.6 liters. Now the "8" is the revision #, but it doesn't necessarily mean that it's the 8th revision in that series....like, I've seen a D16Y5, and a Y7, but no D16Y2 or anything. I think the Y is also part of the revision, because there's also the D16Z6...I hope this helps
