5.7L Engine Oil Dipstick
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check
the level.

Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine
oil is changed. Change
both
the fluid and filter every 15,000 miles
(25 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
Uses such as high performance operation.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, change the fluid and filter every
100,000 miles (166 000 km).
See “Scheduled Maintenance Services”
in the Index.
How to Check

choose to have this done at your Chevrolet dealership

Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if
you have been driving:
When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180°F
to 200°F
(82°C to 93°C).
Checking Transmission Fluid Hot
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
( 10" C). If it's colder than 50°F (lO"C), drive the
vehicle in
DRIVE (D) until the engine temperature gage
moves and then remains steady for 10 minutes. Then
follow the hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine
off and is used
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are
50°F (10°C) or
more. If it's colder than
50°F (lO°C), you may have
to idle the engine longer. Should the fluid level be low
during a cold check, you
must perform a hot check
before adding fluid. This will give you
a more accurate
reading of the fluid level.

1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom of

Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind
of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.

3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir is
filled with hydraulic clutch fluid.
It isn’t a good idea
to “top off’ your clutch fluid. Adding
fluid won’t correct a leak.
A fluid loss in this system could indicate
a problem.
Have
the system inspected and repaired.

Refer to the Maintenance Schedule to determine how
often you should check the fluid level in your clutch
master cylinder reservoir and for the proper fluid. See

How to Check
The proper fluid should be added if the level is below

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often
to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler plug hole.
What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 12345977) or
SAE 8OW-90 GL-5 gear lubricant.
Limited-Slip Differential
To add lubricant when the level is low, use Axle
Lubricant (GM Part
No. 12345977). To completely refill
after draining, add 4 ounces (1 18 ml)
of Limited-Slip
Differential Lubricant Additive
(GM Part No. 1052358).
Then fill to the bottom
of the filler plug hole with Axle
Lubricant
(GM Part No. 12345977).

Downloaded from www.Manualslib.com manuals search engine Checking Coolant
5.7L Engine Only
When your engine is cold, check the dipstick on the cap
of the coolant recovery tank. The coolant level should
be at
COLD, or a little higher. When your engine is
warm, the level on the dipstick should be up to HOT,
or a little higher.
If this light comes on, it
means you’re low on
engine coolant.
Adding Coolant to the Recovery Tank
If you need more coolant, add the proper DEX-COOL’
coolant mixture at the coolant recovery tank, but only
when your engine is cool.
If the tank is very low or
empty, also add coolant to the radiator. See “Engine
Overheating” in the Index for information.
