It is generally recommended that you change the power steering fluid in your Toyota at least once every two years or every 50,000 miles. The owner's manual can tell you when you need to change the power steering fluid. There are also some specific signs that you should look out for.
The Color of the Fluid
You can check the color of the power steering fluid in your Toyota in order to determine when the power steering fluid needs to be changed. Power steering fluid is typically a bright red color. If the power steering fluid is dark, then it likely needs to be changed. You should also check for particles in the fluid. The contaminants in the power steering fluid are likely already in your vehicle's system.
Steering Problems
You should pay attention to how easy it is to steer your vehicle. If your steering wheel feels stiff, then it may be caused by the power steering fluid. Your steering wheel may also feel too loose if the fluid is low. It can be dangerous for you to drive a vehicle with steering problems. You may not be able to turn the wheel in time to avoid an accident.
Steering Pump Failure
The steering pump in your Toyota is what reduces the amount of effort that you have to put in in order to steer. If your steering fluid is in need of replacement, then the steering pump will have to work a lot harder. This can create a lot of heat and friction. The damage that is done can be extremely expensive to repair. It may also be harder for you to turn your steering wheel.
Other signs of steering pump failure include whining noise, squealing noise and a red brown fluid underneath your vehicle.
