Overheating

Hello, were any of those components proven to be failed, or were you just replacing parts based off of guesses? Have you ensured there are no air pockets in the cooling system? After replacing so many components, it's essential to purge the air. Is the fan turning on? When you turn the air conditioning system on, does the fan turn on? When does the overheating occur? While driving down the road? While sitting still and running? Both?
