2007 CHEVROLET AVEO clutch

Hydraulic Clutch
There is one reservoir for both the brake and the
hydraulic clutch fluid. SeeBrakes on page 299
for more information.
The hydraulic clutch linkage in your vehicle is
self-adjusting. The master cylinder reservoir
is filled with hydraulic fluid.
A fluid loss in this system could indicate a
problem. Have the system inspected and repaired.
When to Check and What to Use
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. SeePart B: Owner Checks and Services
on page 389andPart D: Recommended Fluids
and Lubricants on page 396.
How to Check and Add Fluid
To check the fluid level, look on the side of the
reservoir. If the fluid reaches the MAX (A) mark on
the reservoir, the fluid level is correct. If the fluid
does not reach the MIN (B) mark on the reservoir,
then fluid needs to be added. The reservoir is
located near the back of the engine compartment
on the driver’s side of the vehicle. SeeEngine
Compartment Overview on page 276for
more information on location.

Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for uid expansion if freezing
occurs, which could damage the tank if it is
completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
the vehicle’s windshield washer system
and paint.
Brakes
Brake Fluid
Your vehicle has
one reservoir for both
the brake and clutch
hydraulic systems. It is
filled with DOT-3
brake fluid. SeeEngine
Compartment
Overview on page 276
for the location of
the reservoir.
There are only two reasons why the brake fluid
level in the reservoir might go down. The first is that
the brake fluid goes down to an acceptable level
during normal brake lining wear. When new linings
are put in, the fluid level goes back up. The other
reason is that fluid is leaking out of the brake or
clutch system. If it is, you should have the brake/
clutch system fixed, since a leak means that sooner
or later the brakes will not work well.
299

So, it is not a good idea to top off the brake fluid.
Adding brake fluid will not correct a leak. If
you add fluid when the linings are worn, then you
will 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.
{CAUTION:
If your vehicle has too much brake uid, it
can spill on the engine. The uid will burn
if the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake and/or clutch
hydraulic system.
When the brake fluid falls to a low level, the brake
warning light will come on. SeeBrake System
Warning Light on page 163.
What to Add
When you do need brake fluid, use only DOT-3
brake fluid. Use new brake fluid from a sealed
container only. SeePart D: Recommended Fluids
and Lubricants on page 396.
Always clean the brake fluid reservoir cap and the
area around the cap before removing it. This
will help keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake
system, the brakes may not work well.
This could cause a crash. Always use the
proper brake uid.

Selecting the Right Schedule
First you will need to decide which of the
two schedules is right for your vehicle. Here is
how to decide which schedule to follow:
Short Trip/City Denition
Follow the Short Trip/City Scheduled Maintenance if
any one of these conditions is true for your vehicle:
•Most trips are less than 5 miles (8 km).
This is particularly important when outside
temperatures are below freezing.
•Most trips include extensive idling, such as
frequent driving in stop-and-go traffic.
•If the vehicle is used for delivery service,
police, taxi, or other commercial application.
One of the reasons you should follow this schedule
if you operate your vehicle under any of these
conditions is that these conditions cause engine oil
to break down sooner.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km):Engine Oil and
Filter Change (or 3 months, whichever occurs first).
Every 6,000 Miles (10 000 km):Tire Rotation.Every 15,000 Miles (25 000 km):Engine Air
Cleaner Filter Inspection. Passenger Compartment
Air Filter Replacement. Drive Belt(s) Inspection.
Every 30,000 Miles (50 000 km):Engine Air
Cleaner Filter Replacement. Spark Plug
Replacement. EVAP System Service. PCV System
Service. Timing Belt Inspection. Brake/Clutch Fluid
Change (or 24 months, whichever occurs first).
Every 42,000 Miles (70 000 km):Engine Oil Pan
Drain Plug Washer Replacement.
Every 60,000 Miles (100 000 km):Spark Plug
Wire Replacement. Timing Belt Replacement.
EVAP System Solenoid Valve Replacement.
Every 90,000 Miles (150 000 km):Fuel Filter
Replacement.
Every 150,000 Miles (240 000 km):Cooling
System Service.
These intervals only summarize maintenance
services. Be sure to follow the complete scheduled
maintenance on the following pages.
375

Long Trip/Highway Denition
Follow this scheduled maintenanceonlyif none of
the conditions from the Short Trip/City Scheduled
Maintenance are true. Do not use this schedule
if the vehicle is driven in a dusty area or used off
paved roads. Use the Short Trip/City schedule
for these conditions.
Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break
down slower.
Long Trip/Highway Intervals
Every 7,500 Miles (12 500 km):Engine Oil and
Filter Change (or every 12 months, whichever
occurs first). Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air
Cleaner Filter Inspection. Passenger Compartment
Air Filter Replacement. Drive Belt(s) Inspection.
Every 30,000 Miles (50 000 km):Engine Air
Cleaner Filter Replacement. Spark Plug
Replacement. EVAP System Service. PCV System
Service. Timing Belt Inspection. Brake/Clutch Fluid
Change (or 24 months, whichever occurs first).Every 60,000 Miles (100 000 km):Spark Plug
Wire Replacement. Timing Belt Replacement.
EVAP System Solenoid Valve Replacement.
Every 90,000 Miles (150 000 km):Fuel Filter
Replacement. Engine Oil Pan Drain Plug Washer
Replacement.
Every 150,000 Miles (240 000 km):Cooling
System Service.
These intervals only summarize maintenance
services. Be sure to follow the complete scheduled
maintenance on the following pages.Short Trip/City Scheduled
Maintenance
The services shown in this schedule up to
100,000 miles (166 000 km) should be repeated
after 100,000 miles (166 000 km) at the same
intervals for the life of this vehicle. The services
shown at 150,000 miles (240 000 km) should be
repeated at the same interval after 150,000 miles
(240 000 km) for the life of this vehicle.
