<p>My mom's Lincoln LS has such a system (I believe it has a
British-built engine, same as the Ford-built Jags). Because of
the steep slope of the bonnet, the top of the radiator is below
the high point in the engine's cooling system. You have to vent
the air in the high point--sometimes called 'burping' the
engine--but, fortunately, the Lincoln has a vent that can be
opened.</p>

<div>The main purpose of putting a higher pressure cap is to
stop the continues loss of coolant after shutting the engine
down and the engine temp going up over the 212 point. By
putting a 10 or 13 max pressure cap you have raised the
boiling point 10 to 20 degrees thus stopping the coolant
loss.</div>

<div>On your newer cars today they need a much higher pressure
cap because the run the engine temp much higher to reduce
emissions. I have seen some new Jaguars and Land Rovers that
are running a 25 lb cap. As well as cooling systems that you
can not fill up correctly with out using a vacuum type
filler. Due to the fact that there will be air pockets in
the cooling system that you can not remove any other way.</div>
