Engine Coolant - GMC Chevrolet Tahoe 2003 Manual

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Part D:
Recommended Fluids and Lubricants on page 6-18 .
Add fluid only after checking the transmission fluid while
it is hot. (A cold check is used only as a reference.) If
the fluid level is low, add only enough of the proper fluid
to bring the level up to the HOT area for a hot check.
It doesn't take much fluid, generally less than one
pint (0.5 L). Don't overfill.
Notice: We recommend you use only fluid labeled
®
DEXRON -III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON
not covered by your new vehicle warranty.
•
After adding fluid, recheck the fluid level as
described under How to Check .
•
When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle
down to lock the dipstick in place.
