You may have air pockets trap in the cooling system.
Yes, air pockets can form in a vehicle's cooling system, typically due to improper filling, leaks, or coolant evaporation. These air pockets can disrupt coolant flow, leading to overheating and potential engine damage. It's important to regularly check the cooling system and bleed any trapped air to ensure optimal performance. If you're experiencing overheating issues, it's advisable to inspect for air pockets and address them promptly.

The cooling system
Air in the system. Bleed the cooling system and remove any trapped air pockets.
Have you done a rebuild? Is this why your trying to purge the cooling system? Typically you will need to run the vehicle till the temp gauges reads near overheating, then allow the vehicle to nearly cool and remove the radiator cap. This allows air pockets to be pushed through the system. You can also run it to normal operating temperature and slowly crack the radiator cap allowing the system to expell excess pressure.
Back flushing on a cooling system is when you get all of the trapped air out of your cars cooling system. This will make your vehicle run better after you do it.
Should bleed all vehicles after the system has work done to it to get rid of air pockets
