Land Rover Pressurized coolant recovery system vs passive?

[Sandhiller]

So, have not found anything on this but my old 60 has a bad cap, tube for the coolant recovery jug. I noticed that it appears to be an "open" system and understanding that pressure plays a crucial part in controlling temperature wouldn't it be wise to just install a pressurized recovery bottle instead? Thoughts

Not really sure what is being asked here?

Your radiator cap creates the pressurized system. It has nothing to do with the overflow jug.

Imo pressurizing external plastic reservoirs is always a bad idea.

Right, the cap is pressurized but once coolant goes to the jug, how does it re-enter the system? My thought was to add an aluminum sealed recovery jug. That way when then system cools, it creates vacuum, pulls the coolant back in to the radiator.

How do you think it works now?
If the straw is proper in the recovery bottle, suction from cooling pulls it back into the radiator.

I don't know, don't have anything but a bottle, rebuilding a 60. I don't know how it gets back in if the cap is spring loaded?
My cap and straw etc is all broken, falling apart, I'm going off the cap design that its a one way flow.
