Check the fluid level on the dipstick. If
necessary, add automatic transmission
fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (40 C—80 C or 104 F—175 F). You
may also check the level when the fluid
is cold (about room temperature,
0 C—40 C or 32 F—104 F) if the engine
has not been run for about five hours.
a. Clean all dirt from outside of the reser- voir tank.
b. Remove the reservoir cap by turning it counterclockwise and wipe the dipstick
clean. c. Reinstall the reservoir cap.
d. Remove the reservoir cap again and look at the fluid level. If the fluid is
cold, the level should be in the “COLD”
range on the dipstick. Similarly, if it is
hot, the fluid level should be in the
“HOT” range. If the level is at the low
side of either range, add automatic
transmission fluid DEXRON II or III to
bring the level within the range.
e. After replacing the reservoir cap, visu- ally check the steering box case, vane
pump and hose connections for leaks
or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (60 C—80 C or 140 F—175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 C—30 C or 50 F—85 F) if the engine
has not been run for about five hours.
