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

Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the ”COLD” range. Similarly,
if it is hot, the fluid level should be in the ”HOT” 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.
