If it gets hot real soon it may be the head gasket , do a compression test , is the exhaust white ? Is there goop under the oil fil cap ?

How are you bleeding the system ? Try bleeding system like this remove cap from overflow tank add antifreeze to full mark leave cap off and start vehicle and let idle you will notice level in tank start to rise this is normal once thermostat starts to open level in tank will drop add more antifreeze to full mark then put cap back on. All air will be removed from system if antifreeze fills up tank and starts to overflow most likely bad head gasket.

No white smoke and did Compression test We did it that way the 1st time in then drove the car and realised is leaking cooling then started watching YouTube videos and realise that there is a bleed line next to the overflow tank and that this car is particular on how you bleed it we ordered a new cap for the thermostat housing because it didn't come with a new one so hopefully that will help
I have the same problem and did the exact thing. did buying a new cap work?
