What do I look for when checking power steering fluid?
Check levels with the engine off.
- Locate the power steering reservoir, confirm it’s the power steering fluid by looking at the label on the cap and remove the top.
- If made of clear plastic, the full and low indicators on the outside of the tank will indicate the current level of fluid.
What does the power steering analyzer measure?
Installing the Power Steering System Analyzer (PSSA) The PSSA measures flow and pressure and applies a load to the pump through the steering systems hydraulic pressure line. Depending on the model of PSSA being used, an arrow showing the direction of the oil flow is displayed.
Can you overfill your power steering fluid?
In rare instances, overfilling power steering fluid can cause a fire in your engine. Most modern power steering systems will have a way for excess pressure to leave. When the power steering fluid releases and distributes itself over the engine’s parts, it can cause a fire.
How to diagnose a power steering problem?
Depending on the particular issue, always start your diagnosis by checking for the most obvious, like low system fluid, a loose or worn drive belt or serpentine belt, and underinflated tires.
Where to find correct test number in steering diagnostics manual?
Locate correct test number in the TEST PROCEDURES section, and follow the test procedure. When you are done with the test, note the results and correct the root cause. If condition still exists, keep going through the chart (if necessary, to correct the problem). The results of some tests will need to be recorded.
What do you need to know about a steering system?
This device is a combination flow meter, shut-off valve, and pressure gauge. This tool will allow you to measure flow and pressure, and provide a load on the pump through the hydraulic lines of the steering system. This tool is required to correctly analyze a steering system.
How does the pump work in a power steering system?
In each power steering system type, the pump delivers fluid to the control valve. The control valve opens a pressurized flow to and from the hydraulic cylinder and responds directly to input from the pitman arm or steering shaft. The actuation of the control valve is based on input geared to slower vehicle speeds where assist is needed the most.
