11.
NOTE:
Venting reservoir is necessary in this
"sealed-in" unit to equalize air pressure in
reservoir to that of the atmosphere. This
operation prevents the possibility of hydraulic
fluid being forced under pressure from dis-
connected lines and causing damage to trim or
body finish.
Disconnect hydraulic lines and cap open fittings
to prevent leakage of fluid. (Figs. 13-59 and
13-60).
Use a cloth to absorb any leaking
fluid, then remove unit from rear compartment.
Installation
1. If a replacement unit is being installed, fill
reservoir unit with specified Delco No. 11 Hy-
draulic Fluid (GM Hydraulic Brake Fluid Super
No. 11 or its equivalent). See "Filling of
Hydro-Lectric Reservoir".
2. Connect
hydraulic
hoses,
engage attaching
grommets in panel and connect wiring.
3. Connect battery and operate top through its up
and down cycles until all air has been "bled"
from hydraulic circuit. See "Filling of Hydro-
Lectric Reservoir".
4. Check connections for leaks and recheck fluid
level in reservoir.
5. Install all previously removed parts.
