POWER STEERING FLUID
Inspection
FLUID LEVEL
1. Check fluid level with engine stopped.
2. Ensure that fluid level is between MIN and MAX.
3. Fluid levels at HOT and COLD are different. Do not confuse them.
HOT: Fluid temperature 50 - 80°C (122 - 176°F)
COLD: Fluid temperature 0 - 30°C (32 - 86°F)
Recommended fluid: Refer to MA-10, "Fluids and Lubricants".
Fluid capacity: Refer to ST-47, "General Specifications". See: Specifications/Mechanical Specifications/Steering/Steering Gear/General
Specifications
CAUTION:
^
The fluid level should not exceed the MAX line. Excessive fluid causes fluid leakage from the cap.
^
Never reuse drained power steering fluid.
FLUID LEAKAGE
^
Check hydraulic connections for fluid leakage, cracks, damage, looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80°C (122 to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right stop.
3. Hold steering wheel at each lock position for five seconds and carefully, check for fluid leakage.
CAUTION:
Never hold the steering wheel in a locked position for more than 10 seconds. (There is the possibility that power steering oil pump
assembly may be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten connector as this can damage O-ring, washer
and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to ST-38, "EXCEPT FOR SPORT MODELS: Inspection" (Except for sport
models), ST-43, "SPORT MODELS: Inspection" (Sport models).
