10. REFILLING AND AIR BLEEDING HYDRAULIC SYSTEM
CAUTION: Do not deviate from instructions or damage may occur.
NOTE: The following procedure will require an assistant for steps 10 through 13.
1.
2.
3.
4.

Allow vehicle to cool to room temperature.
Verify that all power steering hydraulic connections are made and tightened to specifications.
Turn front wheels fully left, lightly touching wheel stop.
Fill power steering fluid reservoir to top just below neck and install the power steering fluid reservoir
cap.
5. Start the engine. After two seconds, stop the engine.
CAUTION:
• Do not crank and run engine for more than two seconds or new air may be drawn
into the power steering system and pump damage may occur.
• Do not turn steering wheel at this time or new air may be drawn into the power
steering system and pump damage may occur.
6. Remove power steering fluid reservoir cap and fill power steering fluid reservoir to top just below neck.
Reinstall power steering fluid reservoir cap.
7. Repeat Steps 5 and 6 until power steering fluid level stabilizes at the top of reservoir just below the
neck.
NOTE: Tank will need to be filled approximately 4 – 6 times. If power steering fluid is extremely foamy,
allow vehicle to stand for a few minutes, then repeat Steps 4, 5 and 6.
8. Remove power steering reservoir cap.
9. Verify that power steering fluid has stabilized to top of reservoir just below neck. Add power steering
fluid if necessary.
NOTE: Complete steps 10 through 13 without stopping between steps.
10. Have an assistant start the engine. The power steering fluid reservoir level will immediately begin to
drop.
11. Quickly add power steering fluid to keep the fluid level at the COLD MAX line until the fluid level has
stabilized.
12. Keep engine running and have the assistant slowly (approximately 90° [1/4 turn] per second) turn
the steering wheel completely from left to right, then back to the left, lightly contacting the steering
stops at the end of each turn, while adding power steering fluid to keep fluid level at the COLD MAX
line.
13. Reinstall the power steering reservoir cap, then have assistant stop the engine.
14. With the engine stopped, check the power steering reservoir fluid level.
15. Remove power steering reservoir cap and add or remove fluid so that the level is at the COLD MAX
line. Reinstall the power steering reservoir cap.
16. Start the engine and moderately (approximately 180° [1/2 turn] per second) turn the steering wheel
from left to right, then back to the left, lightly contacting the steering stops at the end of each turn.
Stop the engine.
17. With the engine stopped, check the power steering reservoir fluid level.
18. Remove power steering reservoir cap and add or remove fluid so that the level is at the COLD MAX
line. Reinstall the power steering reservoir cap.
19. Repeat steps 16, 17 and 18 until the power steering reservoir fluid level has stabilized to the COLD
MAX line and no air bubbles or foam exist in the fluid.
NOTE: If power steering fluid is extremely foamy, allow vehicle to stand for a few minutes, then repeat
Steps 9 through 19 until air bubbles or cloudiness do not exist.
20. Adjust final fluid level to COLD MAX line at a fluid temperature of 0° - 30°C (32° - 86°F).
21. Reinstall the power steering reservoir cap.
22. Inspect for power steering fluid leaks.

11. Install engine under cover.


Install the (4) engine under cover bolts: torque to 13.5N.m (10 ft-lb)

12. Install front under cover by model.


Standard: Install the (6) front under cover bolts: torque to 13.5N.m (10 ft-lb)



Pro-4X: Install the (3) bolts and (4) hex head bolts: torque to 13.5N.m (10 ft-lb)

13. Submit a warranty claim using the claims information for the Inspection/Repairs
completed.
14. Release the vehicle, inspection complete.
