it works by convection and radiation.
the energy that is generated by the engine that doesn't go into making the pistons go up and down is heat energy. too much of this is bad for your engine so what you have is a water jacket surrounding the hottest parts of your engine. in this jacket there is water. the heat transfers by conduction into the water and through a process of thermal dynamics and the water pump the hot water is taken from the engine and then goes through the radiator. now comes the really good bit. cold air is forced through the radiator by the movement of the vehicle through the air, there is also a fan used to draw air through the radiator so even when you are not moving you still get air flowing through the radiator.
the radiator has a number of water ways in it and these water ways have fins on them. so with the air rushing past the fins the heat that has conducted itself from the water into the metal of the fins via the radiator core is taken away leaving cooler water to recirulate back to the engine.
there are a number of variation on this simple but effective idea these include but are not limited to electric fans and a smaller radiator in the vehicle cab that can be used as a heater ( except the one in series landrovers)
simple really, i'm surprised you didn't know

if yer hole ain't too big you can bung some araldite over it. when i was in australia i hit a washout in me van and the engine and box jumped forward stuffing the fan through the rad, leaving a hole about 4" by 1/4" quick mix up of araldite and it was good to go in 30mins. was still like that when i sold it some 4000 miles later.
yehh Slob - had the same idea - pulled rad out - squashed damaged fins flat with pliers ( 3 core rad so middle ones were a job to get at ) and applied coat of superglue on outside of fins/ radweld on inside.
Seems watertight at moment and should last until I can get myself off to Matlock to replace it
if a job ain't worth bodging it's not worth doing

Steady on you chaps - this is getting WAY too serious. I'm off to the Gaylander section for some fun...

What about the clothes peg on the choke? Was that an optional extra or standard equipment?

Yeah, but then you had the old "What do I do with the other glove?" dilemma...
in the 70's I had a HB Viva ( thats a car not a pencil B4 anyone comments ) who's wings were held on by lashings of cellotape , the horn used to go off in time to the indicators and the exhaust back box was a length of scaffolding pipe.
Obviously it provideda good background in ' bodging ' so I can now keep a landy running
