Nissan Sentra FE Radiator Install and Cooling System Bleeding

My NIssan Sentra has an overheat schedule. After I top up my coolant the car would overheat after a couple of days. I do not see any visible leaks but cooling systems gets drained of coolant somehow.
Suspecting it was the radiator I had my radiator checked and yes, there were several small leaks. I had it repaired and its now time to install. :)
