5.2 Adding coolant following an engine over-
heat
If the engine overheats, the amount of coolant may
be insufficient not only in the reservoir tank but also
in the main body of the radiator.
Refer to "If the engine overheats" with regard to the
filling of coolant in situations where the engine has
overheated.
WARNING
Never remove the radiator's pressure cap
while the coolant is still hot. Carelessly
removing it is dangerous since boiling cool-
ant and hot steam will gush out and could
scald you. Only after the coolant has cooled
down sufficiently, remove the pressure cap
by gripping it in a folded piece of thick cloth
and opening it slowly.
