(-36°C) to ensure protection
against corrosion and loss of
engine coolant from boiling.
This should be done even if
freezing temperatures are not
expected.
Add ethylene glycol-based
antifreeze when antifreeze has
to be added because of engine
coolant loss or if more
protection against freezing at
temperatures lower than -33°F
(-36°C) is needed. Do not use
an alcohol-based or
methanol-based antifreeze, or
plain water. They boil at a
lower point, and do not provide
corrosion protection.
Thermostat
The engine coolant temperature is
controlled by a thermostat, which
stops engine coolant flow through
the radiator until a preset
temperature is reached. This
thermostat is installed in the
engine coolant inlet on the front
of the engine block. The same
thermostat is used in both winter
and summer.
Other Required
Maintenance
Brake Master Cylinder
Check the master cylinder fluid
level in the reservoir every time
you check the engine oil level.
The level should be between the
MAX and ADD level line. If the
level is lower than the ADD level
line, fill to the MAX level line
with DOT-3 or DOT-4 fluid.
