Keeps overheating. Have to keep adding coolant. No leaks . Drives fine. Gets hott

Hello, with all those components changed in the cooling system, my initial reaction is wondering if the cooling system has been purged of air. If there are air pockets in the cooling system, it can act like overheating...and you'll keep having to add coolant. Seek professional help purging the cooling system, or "burp" the air yourself -- however, this is potentially dangerous without proper tooling or procedure following, as hot coolant will burn you.
