Oil Level Indicator
Dipstick in oil pan or fill cap
NOTE
To check oil level on engines with the dipstick mounted in the
fill cap, remove the cap and wipe the dipstick clean. Insert the
cap back onto the oil fill tube, then remove to check level. It is
not necessary to screw the cap back into the fill tube when
checking level. DO NOT add oil if level is within the “safe”
range. If needed, add oil to bring level within the “safe” range.
Screw cap fully into fill tube after checking level.

j. Cooling System
Capacity
6 U.S. quarts (5.68 liters) -- includes 1 quart (0.95 liter) in
coolant recovery bottle. (Refer to section 4.4.5)
Anti--Freeze:
Conventional
The cooling system may be factory charged with a 50/50 mix
of ethylene glycol and water. This mixture provides protection
to --34F (--37C). For replacement, use a low silicate anti--
freeze meeting GM specifications GM 6038M or equal. Again,
a 50/50 mix is recommended.
Anti--Freeze:
Extended Life
The cooling system may be factory charged with a 50/50 mix
of extended life coolant (ELC) and deionized water. This mix-
ture provides protection to --34F (--37C). For replacement,
with extended life coolant (ELC) meeting GM specification
GM6277M and deionized water. Again, a 50/50 mix is recom-
mended. Extended life coolant is red or orange in color.
DO NOT mix with conventional coolant.
