No you did not do anything wrong, it was the festive season and the forum is not as active as it was in the old days, dead center is right, just for in case, replace the sensor although it was showing you that it was starting to overheat, so it should be fine.

Welcome!

The alu radiators are better than the ones that came out with ours, no problem at all. The temp sensor you can find at any midas or autozone, just take a sample, think the best make is "Echna" or something like that, cant remember the right name.
