I replaced my radiator a couple weeks back, and everything seemed fine despite the temp gauge raising to a bit over the half mark. After a bit more of longer drives, the gauge now goes past 3 but and can get to 4. I have a few questions. How can i make sure that I purged the engine of air correctly. Is there a valve or do i just pop the top and let the engine run.
I cant say theres a leak because the coolant level has never changed
