What Is Power Steering Fluid? How To Change Power Steering Fluid?
Although power steering fluid is one of the most important components of a car’s steering system; steering hydraulic oil is often neglected and drivers do not even know how to control their vehicle’s steering fluid. By knowing basically what steering fluid is; how it works and how to maintain it; you can be sure that your vehicle’s steering system is always operating at high performance. In this publication, we offer a complete guide to steering hydraulics that will leave no question mark in your mind.
What Is Power Steering Fluid?
Steering hydraulic fluid provides hydraulic support for the power steering system. Steering hydraulic oil is mineral oil or synthetic oil reinforced with additives to prevent foaming; suppress corrosion and provide high performance lubrication of power steering pump and steering gear.
What does Power Steering Fluid do?
Without getting too technical, power steering fluid is the hydraulic fluid that transmits power in your steering system. To put it in a little more detail it helps your vehicle’s steering pump apply pressure to both sides of its piston; allowing you to turn the wheels with ease.
When to change the Power Steering Fluid?
Power steering oil works in a relatively clean environment, so it will last a long time. Some vehicle manufacturers don’t even have a recommended service interval for power steering fluid. Of course, this does not mean that the steering fluid will not be replaced; after many kilometers and years of service; particles of wear on the steering pump and steering gear can contaminate the hydraulic oil.
Corrosion inhibitors can also wear out over time; and very high temperatures and extremely cold temperatures can cause the liquid to oxidize and break down. To give a general average, changing the steering hydraulic oil every 5 years or 100,000 km will help to extend the life of the power steering system and prevent possible malfunctions.
Why is the Power Steerig Fluid low?
The most common problem in hydraulic steering systems is oil leaks. Power steering oil can leak from hoses and hose connections, power steering pump or power steering gear, and finally the steering box. Seals in the power steering box and O-ring seals in the spool valve assembly are frequent points where fluid leaks occur.
Power steering fluid is usually colorless (clear), but may be pink or red if the steering system uses ATF Fluid. The decrease in the steering hydraulic fluid reservoir is an indication of a leak or leak in the system. Taking a look at the floor where you shine your vehicle and checking if there is any oil leaking allows you to know if there is an oil leak in your vehicle.
If the steering hydraulic oil level is too low, the steering pump will run noisily or air will mix into the system and you will lose steering feel. The vented system steering hydraulic fluid is incompressible and the power steering system does not transfer pressure from the pump to the steering gear. As a result; if air enters the power steering system; there is a decrease in pressure and the softness of the power steering gradually becomes harder.
How do we know if the power steering fluid is missing?
Check the fluid level in your reservoir if your power steering is making all sorts of noises, especially when parking your vehicle or when you move slowly.
Jerky or tense power steering
Sometimes when you try to turn your steering wheel in a standard way from one direction to another, you will feel a jolt or a vibrating strain. You can feel this situation in the maneuvers you make while parked.
It becomes difficult to turn the steering wheel
As hydraulic steering systems lose fluid, they operate less efficiently. Eventually, you’ll start to feel the difference as you move the steering wheel left and right, making the wheel a lot harder than it normally would.
Screaming steering wheel
When you turn the steering wheel to the right or solo, you should immediately check your power steering oil reservoir if there is a high-pitched scream coming from your steering pump.
Oil deposits under the vehicle
If oil puddles form every time you park your vehicle, it means that your vehicle has an oil leak. This oil leak can have many causes. Possible causes include oil leaking from your steering system. By checking the type of oil, you can guess what liquid it is.
