How To Check And Add Fluid - GMC 2003 GMT560 T-Series Owner's Manual

Clutch Pedal Free Travel
If you have a manual transmission, your clutch will need
adjustment when pedal free travel gets down to about
1/4 inch (32 mm), as measured at the clutch pedal pad.
You should have 1 1/2 to 2 inches (38 to 51 mm) of
clutch pedal free travel. See Scheduled Maintenance on
page 6-5 for more information.
If your clutch ever needs service, be sure to use only
GM clutch replacement parts.
Electric/Hydraulic Parking Brake Fluid
If you have an electric/hydraulic parking brake, a
good time to check the fluid level is when you check the
fluid levels under the tilt cab. The fluid reservoir is
located in the component box beneath the driver's side
of the cab on the frame rail.
If you need to add fluid, use Dexron
Transmission Fluid. See Scheduled Maintenance
on page 6-5 .

How to Check and Add Fluid

First, apply the parking brake. To check the fluid level,
look at the MAX and MIN lines on the side of the
reservoir. If the level is below the MAX line, add fluid.
To add fluid, clean away any dirt around the reservoir
cap. Remove the reservoir cap and add enough fluid to
bring it up to the MAX level.
