The car runs hot, mostly in summertime?

I would think the radiator is to blame, can you please lower the coolant level to inspect the cooling tubes for calcium build up at the tube openings? Here is a guide to help you see what I am talking about. Also use a flashlight to inspect for dirt or a plastic bad that has gotten stuck in front of the radiator.

I have also included how to change the radiator out in the images below in case you need it. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
