Clutch Adjustment
The clutch linkage in your vehicle should be checked as
recommended
in your Maintenance Schedule. To check,
push the clutch pedal down with your hand until you
feel some resistance to movement of the pedal. If the
pedal moves freely up to
1 inch (25 mm) or so before
you feel resistance
to the travel, adjustment isn’t needed.
If there is no free travel or very. little (less than 5/8 of an
inch
(1 6 mm)), see your dealer for adjustment.

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” in
the Index.
A 50/50 mixture of water and the proper coolant for
your Geo will:
Give freezing protection down to -33 “F (-36°C).
0 Give boiling protection up to 258°F (125°C).
Protect against rust and corrosion.
Help keep the proper engine temperature,
Let the warning lights and gages work as
they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets
GM
Specification 1825-M, which won’t damage aluminum
parts. You can also use a recycled coolant conforming
to
GM Specification 1825-M with a complete coolant flush
and refill. If you use this mixture, you don’t need to add
anything else.
/i CAUTTON:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix
will. Your vehicle’s coolant warning
system is set for the proper coolant
mix. With
plain water
or the wrong mix, your engine could
get too hot
but you wouldn’t get the overheat
warning. Your engine could catch
fire and you or
others could be burned. Use a 50/50 mix of clean
water and the proper antifreeze.

operating
your vehicle in an area where the temperature
may fall below freezing, use

system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings
are worn, then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work ’is
done on the brake hydraulic system.
A CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is hot
enough.
You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.
Checking Brake Fluid
You can check the
brake fluid without taking
off the cap.
Just look at the windows on the brake fluid reservoir.
The fluid levels should be above
MIN, If they aren’t,
have your brake system checked
to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the levels
are above MIN and below the top of
each window.

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(IO OOO ro 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon as
possible
and check wheel alignment. Also check for
damaged tires
or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later in this section for
more information.

Protection
Plan
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or
the wrong tire inflation can increase the level
of emissions from your vehicle.
To help protect our
environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
Have you purchased the GM Protection Plan? The Plan
supplements
your new vehicle warranties. See your
Warranty and Owner Assistance booklet, or your Geo
