Maintenance and care
• 3.8L OHV V6 engine
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 the 3.0L V6 Vulcan engine,
check the fluid level on the dipstick.
It should be between the arrows in
the FULL HOT range. Do not add
fluid if the level is within this range.
