    Hello all, I am new to this forum, and new to the life with a Mini Cooper. I bought a 2009 Mini Cooper S, automatic trans 2 door hatchback for my daughter. I love the vehicle, but got a check engine light and getting a code for a thermostat housing and temp sensor. Changed the housing, and the crossover engine coolant tube, but the o ring on the crossover pipe to the water pump is leaking. I ordered a new o ring from Auto Zone and the one I got is not the same number as the one I had researched in other threads and posts. Apparently from what I can gather, the o ring part number I found online is always listed as a 11537548651. The Fel Pro number I bought at autozone says it replaces number 11537548657, and lists all the engine codes it is compatible with, being N12B16A, N14B16A, N14B16C, N16B16A, and N18B16A engines. I have looked on the data plate on the car, and I don't see an engine code listed. So, if anyone can help me to identify if I should have one of the engines listed above, and if anyone has had the same problem, will the 657 o ring work instead of the 651, or do I just definitely need a 651 o ring. I appreciate any help anyone can provide, because I have taken everything apart twice and don't want to take everything back out and in again if I will have the same problem. I would rather not be taking everything out and putting back in a couple more times if I can help it. Thanks for all your help!!

    Welcome to M/A Paulie. Your MCS has an N14 engine. Auto Zone is not a good place to source parts for your MINI.

    I would use Detroit Tuned or even a dealer before Auto Zone.

    Welcome to MA! @Crashton is correct you have an the dreaded N14 motor. But so do I it’s a good motor but does require more attention.
    Detroit Tuned and Out motoring are the best place for parts.

    Thanks for the warm welcome, and letting me know what engine she has. I actually ended up contacting the BMW dealer in Charlottesville to order the O ring. I had found the one I have is for the thermostat housing side, not the crossover tube. I was reading posts and everyone basically said what you all said, and that was get genuine parts... The tube is ok, but the O rings are crap. Hope when they get here I can get it changed and it won't leak anymore. I will keep you all updated.

    That reminds me of the thermostat housing on a Gen 2 MCS. I did one for a friend of mine way back in the day and I remember it being a huge PITA... tubes and wires everywhere!
