Should I drain or flush my coolant and what other products are used besides the coolant itself and I'm using prestone 50/50 mix with distilled water. And could anybody walk me through the steps of doing it?

After the initial fill, before you even cap it up, rev it to 3K and hold it there for 30 seconds or so to purge any air in the system. Then top it off and cap it up, but follow MC's advice and check it again after the next 2-3 drives. It could still need a top off.
