Power Assist Check

Check
1. Check the power steering fluid level and pump belt tension.
2. Start the engine, let it idle, and turn the steering wheel from lock-to-lock several times to warm up the fluid.





3. Attach a commercially available spring scale to the steering wheel. With the engine idling and the vehicle on a clean, dry floor, pull the scale as shown and read it as soon as the tires begin to turn.
^ If the scale reads no more than 28 N (2.9 kgf, 6.4 lbs) the gearbox and pump are OK.
^ If the scale reads more than 28 N (2.9 kgf, 6.4 lbs), check the gearbox and pump.
