Whats This

this is the thermo housing off my fj40, what are the two nuts on here? Can I plug temp sensor into one of these?

They are ports for vsv's. Your temp sender should be on the cylinder head, driver's side nearest the firewall. Should have a black plastic connector and a white (I think) wire coming off of it.

on the lower, one of the ends where the hose slides over is broke... is this a problem?
