Thermostat leak

What is your question?

I've purchased a thermostat housing from AutoZone last week I replaced it with the know with the old and for somewhere reason I put all the Simley back on so the car and after a drive all my coolant that I refilled in the reservoir went bad and just emptied out all through my engine bay.I don't know what to do can you please find out what would be the best bet of having the house connector flush so it out leak anymore

What makes this problem better or worse?

Thermostat hose pipe connector won’t stay on thermostat
