The reason the hose blew off was due to excess pressure. So, the fact that you had overheating before all these things were replaced means we need to dig a little further into that issue.
As for now we can ignore the overheating and focus on the pressure.
This means we need to test the head gasket and find out if this is causing additional pressure in the system.

If the head gasket is okay, then we most likely have a restriction in the system causing the pressure to build and not be vented through the cap. So normally this is a defective cap but if you replaced it then we need to inspect the engine using a laser temperature gauge and look for hot spots to find out if there is a place that is hotter than the surrounding location.
This would indicate a restriction in the system.

If there are no hot spots, then we need to start running through this guide to focus back in on the actual overheating.

Basically, we need to start crossing these things off the list and that will help narrow this down for us.
Please run through this and let me know what you find. Thanks
