Checking Oil Level It is the owner' s respOnsibility to keep the engine oll at the proper level. Check
the oil level at regular intervals (such as every 'o ther fuel stop) and keep it above
th e "Add" line. Rem ember, your engine may use more oil when it is new .
• The best time to check the engine oil level is when the oil is warm, such as
during a fuel stop. First, wait about 5 minutes for the oil to drain back to
the oil pan, Then, pull out the dipstick, wipe
it clean, and push it back down
all the way . Now , pull out.th e dipstick and look at the oil-level on the dipstick.
Some
dipSlicks have "Add" and "Full" lines , Others are marked "Add! Qt"
and "Operaling Range." In all cases, keep the oil level above the
"Add" line. Push· the dipstick back down all the way after taking the
reading. _ A ·dd oil , if needed.
• If you check the oil level when the oil is cold, do no t run the engine first. The cold oil wilJ not drain back to the pan fast enough to give a true oil level.
Engine Oil Additives
There are many extra engine oil additives (or helpers) for sale. Your engine should
not need these extra additives if you use SE-quality or SF·quality engine oil and
change
it as suggested. If you think your engine has .an oil-related problem, talk
to your authorized dealer.
If needed, your dealer can provide you with a tested
and approved oil additive called "GM Engine Oil Supplement."
AUTOMATIC TRANSAXLE FLUID RECOMMENDATIONS
Use the Proper Fluid Use only automatic transmission fluid labe led DEXRON-®II. You can buy this
fluid from your Chevrolet dealer or
othe~,'service outlets.
Check the Fluid Level with care Check the automatic transmission fluid level at each engine oil change. Before
checking the fluid level, set the parking brake and then start the engine. AppJy
the regular brakes and then
'mov e the shift lever through all of the gear ranges,
ending in
"P '·(Park). You must check the fluid level with the engine funning at
slow idle and the car level.

Cooling System Service
The cooling syste m should be serviced at the intervals specifi ed inSection A of
the Maintenan ce Sch edule fold er as follows:
I. W ash the radiatqr cap .and filler neck with clean water. See step J of "Coolant
Replacement" to remove rapiator cap. .
2. C hec k the coolant level in the radiator and have it tes ted for freeze proteCtion . Add·· ethylene gly col antifreeze, if needed, to· m aintain freeze protecti on at -37'C(-34'F),
3~ Have ·the coOlin-g sys tem and radiat or cap tested fo r a press ure capacity of
105 kPa (15 psi) . If a repl acement cap is needed"Hse an AC ca'p,or an
equivalent · cap, designed fOl: coolant recovery system ·s and spe cified for your model;
4. Tighten all radiator hose clamps and heater hose clamps and inspect an hose s.
R
eplace the hose s if they are swollen, "checked" or otherwise worn .
NOTICE: Take care when tightenjng·the hose clemps at tMI radiator. Overtightening COUld. bend or collapse .the radiator fittings.
5. Clean the front. of the radiator core and air condit ioning condenser to re m ove
dirt and oth er·objects. Al so clean the auxiliary engine oil andlor transmission -fluid ' cooler if the vehicle has them.
Coolant, Replacement
At the interval s specified in Section A of the Maintenance Schedule folder, flu sh

• 'Wait until any rem aining press ure (indicated by a hissing sound) is
reliev ed. then press down on the cap an d continue turning it t(j the left.
CAUTION:· To help ~lVoid the danger of being ,burned, do not remove the radiator cap while the angine and radiator are still hot s.c.lding flutd and steam can be bk)wn out under pressure if the·cap is taken off.too soon.
2. Whe n the cap is re m oved, run the eng ine until the upper radiator hose is hot.
(This shows that the thermostat is open and the coola nt is flow ing through
