Refer to the Maintenance
Schedule to determine
how often you should
check the fluid level in your
master cylinder reservoir
and for the proper
fluid. See

Checks and Services
on page 6-19
and
Part D:
Recommended Fluids
and Lubricants on
page 6-26

How to Check and Add Fluid
Check to make sure that the fluid level is at or above
the MIN mark. If the level is below the MIN mark,
see the instructions on the reservoir cap.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating on
page 5-30
.
A 50/50 mixture of clean, drinkable water and the proper
coolant will:
Give freezing protection down to 34°F ( 37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
