CHECKING POWER STEERING
FLUID
The power steering fluid reservoir is located under the
right side engine compartment cover. Before checking
the power steering fluid, remove the cover. (For details,
see Removing the engine compart coversº on page 526.)
Check the fluid level, simply look at the see-through
reservoir. 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
(60C - 80C or 140F - 175F). You may also check the level
when the fluid is cold (about room temperature, 10C - 30C
or 50F - 85F) if the engine has not been run for about five
hours.

4If hot add
Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the COLDº range. Similarly,
if it is hot, the fluid level should be in the HOTº range. If the
level is at the low side of the appropriate range, add automatic
transmission fluid DEXRON
II or III to bring the level within
the range.
To remove the reservoir cap, turn it counterclockwise and lift
up. To reinstall it, turn it clockwise. After replacing the reservoir
cap, visually check the steering box case, vane pump and hose
connections for leaks or damage.

CAUTION
The reservoir may be hot so be careful not to burn
yourself.
NOTICE
Avoid overfilling, or the power steering could be
damaged.
When adding the power steering fluid, avoid spilling
it. The generator under the power steering reservoir
could be damaged if fluid is spilled on it.
