Nissan Altima 2007-2012 Service Manual: Power steering fluid and lines

Inspection

FLUID LEVEL

• Check fluid level with engine stopped.

• Make sure that fluid level is between MIN and MAX.

• Fluid levels at HOT (A) and COLD (B) are different. Do not confuse them.

CAUTION: • The fluid level should not exceed the MAX line. Excessive fluid will cause fluid leakage from the cap.

• Do not reuse drained power steering fluid.

• Recommended fluid is Genuine Nissan PSF or equivalent.
