Warning: Vehicles equipped
with air conditioning:
Components of the air
conditioning system may
obstruct work being undertaken on the
engine, and it is not always possible to
unbolt and move them aside sufficiently,
within the limits of their flexible
connecting pipes. In such a case, the
system should be discharged by a Ford
dealer or air conditioning specialist. The
refrigerant is harmless under normal
conditions, but in the presence of a naked
flame (or a lighted cigarette) it forms a
highly toxic gas. Liquid refrigerant spilled
on the skin will cause frostbite. If
refrigerant enters the eyes, rinse them
with a diluted solution of boric acid and
seek medical advice immediately.
