CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid.
Refer to the scheduled maintenance
guide for the service interval
schedules. If adding fluid is
necessary, use only MERCON
௡ ATF.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. If your vehicle is equipped with a 3.0L V6 engine, check the fluid
level on the dipstick. It should be within the FULL HOT range. Do not
add fluid if the level is within this range.
5. If your vehicle is equipped with a 4.0L SOHC V6 or 2.3L I4
engine, check the fluid level in the reservoir. It should be between the
MIN and MAX lines. Do not add fluid if the level is within this range.
6. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL HOT range. Be sure to put the
dipstick back in the reservoir.
