Hello, I recently bought a new radiator for the 2014 XK which I am repairing. The radiator was listed as compatible but when I’ve come to fit it I notice that the new one has one outlet more than the original. The other three inlets/outlets are identical in size and position. I’m wondering what the additional outlet is for and if I can simply blank it off. The extra outlet is circled in red in the photo. Could anyone advise me please?

 

On my Beemers, I solved an identical problem by looking at a parts explosion for my model and it's variants. Noticed that there were four unique cooling systems for the model.

Not sure where you can find a good X150 parts explosion, tho.

Britishparts has 2 radiators, one (apparently) with the connector you have, Found at: https://www.britishparts.co.uk/jagua...ing-c328#page2
