POWER STEERING SYSTEM
Check the fluid level in the power steering
pump reservoir at each oil change period. This
requires the removal of the engine access cover.
The reservoir is located near the Delcotron
generator. Add GM Power Steering Fluid (GM
1050017) as necessary :
If fluid is warmed up (about 150°F. or 66°C.
- hot to the touch), it should be between
"HOT" and "COLD" marks on the filler cap
indicator.
0 If cool (about 70'F. or 21'C.), fluid should
be between "ADD" and "COLD" marks .
Fluid does not need periodic changing.
STEERING LINKAGE
STEERING SYSTEM
The steering linkage (tie rods) and suspen-
sion should be lubricated, using a Lithium Soap
Multi-purpose grease that meets GM Specifica-
tion 6031-M, at every oil change . Seals should
be checked for damage (see Maintenance Sched-
ule folder) .
BRAKE SYSTEM
BRAKE MASTER CYLINDER
The master cylinder is located behind the
left front access door at the front of the vehicle .
The fluid level in the master cylinder should be
checked at each oil change. Wipe off the brake
cylinder filler cap and unsnap the retainer. A
low fluid level in the front brake master cylinder
reservoir could be an indicator that the disc
brake pads need replacing. The fluid level must
be maintained at 1/a -inch below the top of each
reservoir with Delco Supreme No. 11 or DOT-3
Brake Fluid or equivalent. When replacing the
cap be sure to fasten the retainer securely, tak-
ing care not to let dirt enter the reservoirs .
BLEEDING BRAKES
The need for bleeding brakes is generally indi-
cated by springy, spongy pedal action. Pressure
bleeding equipment must be used and a definite
bleeding sequence and procedure must be fol-
lowed. Consult your GMC Motorhome dealer .
