1994 CHEVROLET BLAZER cooling

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
If you use an improper coolant mix, your engine could overheat
and be badly damaged. The repair cost wouldn’t be covered by
your warranty.
Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when the engine
is cold
and follow the steps under “Adding Coolant” for
the proper way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to add extra
inhibitors or additives which claim to improve the system. These
can be harmful.
Adding Coolant
To Check Coolant
When your engine is cold, the coolant level should be at “ADD,” or a little
higher. When your engine
is warm, the level should be up to “FULL HOT,”
or a little higher.
To Add Coolant
If you need more
coolant, add the
proper mix
at the
coolant recovery tank.

windshield wiper
blade inserts, lift the
wiper
arm away from
the windshield. Pinch
the two tabs on the
wiper arm and slide
the insert out of the
blade. Slide the new
one in place. Make
sure the tabs
are
locked into position.
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°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 cause 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.
