1994 CHEVROLET ASTRO PASSENGER cooling

Downloaded from www.Manualslib.com manuals search engine Air Conditioning
Every now and then have your dealership check your air conditioning
system to be sure it has not
lost any cooling ability. If you think the system
is not working properly, have your dealership
check it out as soon as
possible.
The air conditioning will not work when the temperature is below
40°F
(4 O C).
Lubrication
Accelerator Control System
Refer to the Maintenance Schedule to determine how often the accelerator
linkage pivot points must be lubricated and what type of lubricant
to use.
Accelerator cables and cruise control cables should not be lubricated. Any
cables that are worn or are hard to pull should be replaced.
When cleaning the engine compartment with water or steam, avoid directing
the flow onto the throttle linkage in a manner that would cau\
se moisture
to
enter the cables.
Hood Latches and Hood Hinge
Refer to the Maintenance Schedule to determine how to lubricate the hood
latch and hood hinge assembly.
Sliding Door Tracks
Your vehicle’s sliding door has three tracks which need lubrication.
For the upper and lower tracks, open the door, wipe the track\
clean and then lubricate with Lubriplate
TM White Grease.
For the outside middle track, close
the door after you finish the upper and
lower tracks. Then, wipe
the track clean and lubricate with
Lubriplate
TM White Grease.
Body
Normal use of your vehicle will cause metal to metal wear at some points on
the cab and body
if they are not lubricated.
For exposed surfaces, such as door checks, door lock bolts, lock striker
plates, dovetail bumper wedges, etc., a thin film
of engine oil should be
applied.
Where oil holes are provided in the body or cab, a dripless oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.

Downloaded from www.Manualslib.com manuals search engine Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only with new
GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel nuts
for your
GM model.
NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim,
bumper height, vehicle ground clearance, and tire or tire chain\

clearance to the body and chassis.
