[DML] Re: Question about steel bottle

["therealdmcvegas" <DMCVegas@xxxx>]

Coolant bottles are not designed to break. If excess pressure builds 
in the cooling system for whatever reason (overheating or lack of 
expansion), it is the job of the radiator cap to relieve the 
pressure. Cooling system test kits will not only test the cooling 
system on a car to insure that there are no leaks, but will also test 
radiator caps to insure that they will open @ the appropriate 
pressure.

Why don't $100K cars use plastic bottles? I don't know, because I 
don't own one (although my D certainly looks it ;) ). If I were to 
guess, I'd say because those kind of cars are not in the same class 
as DeLoreans are. Not to say that one is either better or worse. But 
expensive collector cars in this range are usually not driven quite 
as often as DeLoreans, if at all. Hence concern for originality of 
the vehicle is placed ahead of function. There is more that could 
probably be said, but anything else would simply be speculation on my 
part.
