My 1976 landrover 101 forward control's coolant system was originally the type where, when the rad pressurises, it overflows into an atmospheric pressure overflow tank (way below the engine).
My much more modern 1996 discovery 300tdi has a headder above the engine, and the system is sealed.
I assume that, if too much pressure builds up, it vents from 'somwhere' (its never happened to me yet) and then its total loss.
My issue -
When the engine in the 101 was swapped for a TDI, the original cooling system was kept, which i feel uneasy with. I would rather have the headder tank, with a level warning system, located above the head and water pump.
I dont know how radiators are constructed - its not the original radiator in the 101, but its the original design, just a little larger (ie the rad is 10 years or so old, rather than 40). Would i need to take it to 'somwhere' that fabricates radiators for alteration, or would it just be a case of turning up a lump of brass and silver soldering it in where the filler cap is currently?
Currently its got one of these dual sprung caps -
...with this sort of top to the rad (not mine, but the same) -
(note the very small port on the 3:30 ish position, which is the pipe down [and up] from the expansion tank)
