I found an OES Genuine expansion tank/coolant reservoir online for my 99 cadillac

deville BUT? It is not the same shape as the coolant reservoir in my car now. The one under the hood is more of a "boxy shape" while this replacement part I found online is more compact but longer in length..... I've confirmed it on several dozen websites. I just don't want to be disappointed.

Does the size and shape of a coolant reservoir/expansion tank matter?

I found it at autopartswarehouse dot come Part # W0133-1820133 and also partstrain dot com.
Thank you for your answer LeAnne. I went back to the website and realized that the photo listed for it was actual a stock photo. That helped me out tremendously!
