In order to avoid any potentially serious
burns:
Use extreme caution when opening the

coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.
Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.

parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.
