Another thermostat question

[Anonymous]

Hi everyone,
I just installed my new thermostat and housing and it leaks. It does not appear to be leaking from the gasket. Instead it is leaking from a "bolt" on the top of the housing. What does the bolt do? It appears to be some sort of a plug. If so, how do I stop it from leaking?


Thanks

Try unscrewing it, wrapping the threads in teflon tape and putting it back in. That's all I can think of.

That plugged hole is for thermo-vacuum controls in various applications. Thread tape or brushing the threads with Permatex#3 should fix the problem.
