GMC 2004 Canyon - Manual (Page 288)

Hydraulic Clutch
(Manual Transmission)
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir is
filled with hydraulic clutch fluid.
The hydraulic clutch fluid
reservoir cap has this
symbol on it.
It is not necessary to regularly check clutch fluid unless
you suspect there is a leak in the system. Adding
fluid won’t correct a leak.
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 clutch
master cylinder reservoir and for the proper fluid.
See Owner Checks and Services on page 6-9 and
Recommended Fluids and Lubricants on page 6-13.
How to Check and Add Fluid
The proper fluid should be added if the level does not
reach the bottom of the diaphragm when it’s in place in
the reservoir. See the instructions on the reservoir cap.
