Coolant return? (1 Viewer)

[77cruiserguy]

July 1977 FJ40. Second owner. Just received my 40 and I’m confused. My coolant reservoir has a cap that has the port to receive a return line or expansion line but there’s nothing hooked up to it. Am I missing the line or do I have the wrong cap and this is a closed system? Thanks!

There should be a port right under the radiator cap just run a hose from there to the tank.

That’s what I assumed as well. But there’s nothing on the neck under the cap. Hmmm

Probably an after market radiator then.
