Your radiator is the early type cap is not the same so does not have the extra valve and seal to draw the liquid back into the radiator.

So do I not bother with the expansion bottle or can I replace the cap

You need the correct radiator if you are going to use the expansion bottle.

Latter 2As were originally fitted with the later radiator and bottle.

Seems like yours has been fitted with the older style rad.

Think I will leave the existing rad in for now, then if I change it in the future I will then set up the expansion bottle with the new correct rad 👍

Pretty sure that is the right radiator.
Not sure what year your Land Rover is but going by the negative earth badge on the grille panel it has a suffix D or later chassis number, post April 1967.

My one has the same radiator, dated 3/67 with the ribs running side to side on the header tank and I have the expansion bottle as well. It all works very well and I never have to top up the fluid. If you have the radiator and the expansion bottle to hand, fit it and make a superior cooling system.

The pipe from the radiator cap to the expansion bottle should not run through that grommet on the grille panel either, it just connects straight to it running along the front of the radiator.

Looks to me like its just routed down through that gap by the radiator panel. It looks as though its going through the grommet, but I think that's just a wiring feed.

Is it the very late 2a and 3 that got the transparent overflow pipe?

Don't know - the originals I've seen use thick walled black rubber tube ???

Here's a pic of a tatty setup....



Note - if your rad has this type pf rad cap, as fitted to later 2As then you need/can use the rad expansion bottle.

The hose on my one pictured above is the original hose.
It is a black rubber pipe with a wall thickness of maybe 2-3mm. It isn't reinforced hose as that part of the system is not under any pressure. You can remove the cap on the expansion tank even when the engine is up to temperature, just don't try the same on the radiator cap as you will get burnt!

With all this talk of radiators.

Do you have the metal shroud that screws to the plastic shroud in wittsend's pic fitted or not.

I know it gets removed for belt adjustment ease of access sometimes.

I have a metal shroud but not fitted yet
