Coolant system leak

[johninthemountains]

Hi, i have a slow leak on two rubber hoses near the thermostat thing. Atm I've stopped it temporarily with some leakseal stuff. I'm told the corroded metal pipes cannot be changed without the whole block replacement behind the thermostat housing. I'm struggling to get this part. I'm told it would be of no use to take the hoses off, clean up and put new hoses on. Any ideas please as this seems a bit job for a small problem. Or, any idea where i might get the part please? Photos attached ...

Well, thanks but i managed to get the part and hoses as i noticed a leak there too. Maybe, seeing I'm going to need more help in the future, I'll get membership
