1982 dt lc coolant system part

[kiffatola1234]

firstly im sorry but i dont know the name of the part so not expecting a great response
Iam after the part that comes off the coolant hose and goes into the top of the engine by the spark plug.
it sits into the engine with an o seal on it and held in place with one screw.
My part has cracked inside and i require a new one or information where i may get one
Any assistance would be greatly appreciated

Many thanks

Andrew

@Calum I've seen these and the one part looks very similar but not sure if the one end is flush and doesn't actually pop into the block. I may take a punt on it for ten quid.
Thanks for replying

Which part though, can you specify the number so I know what you're actually talking about. Your description is a bit vague.
