Power Steering Fluid Service at Johnny's Automotive
Many newer vehicles have electric power steering and no fluid at all. If yours is hydraulic, we judge the fluid by its color and condition instead of by mileage.
Does my car even have power steering fluid?
Fair question, and on a lot of newer vehicles the answer is no. Electric power steering uses a motor on the column or the rack and has no hydraulic fluid at all. Nothing to check, nothing to change, nothing to sell. Plenty of drivers have paid for a power steering flush on a vehicle that does not have a drop of it in it. We will tell you which type you have, and if yours is electric, that is the end of the conversation.
If your vehicle is hydraulic, there is a pump, a reservoir, hoses, and a rack or gearbox. The pump pushes fluid under high pressure, and that fluid does the actual work of turning the wheels while you park and maneuver. It also lubricates the pump. That pump runs the entire time the engine runs, so the fluid takes a beating from heat, pressure, and thousands of hours of shear.
What we look at is condition. Fresh fluid is clear, red, or amber depending on the type. Old fluid goes brown or nearly black and smells scorched, and it carries fine metal worn off the pump and the seals. That grit is abrasive, and circulating it is how a fluid problem turns into a pump or rack problem. We check level, look at color and smell, check the reservoir screen for debris, and put the photos on your digital inspection so you are looking at the same thing we are.
Worth mentioning to us: a whine or groan that rises as you turn, especially at idle or in a parking lot, steering that feels heavy or notchy, or a shudder in the wheel at full lock. Low or degraded fluid can cause all three.
We should be straight about the limit, though. Fresh fluid does not fix a leaking rack or a worn out pump. If the fluid is dark because a component is on its way out, we will say so, and rack and pinion replacement is its own job with its own quote.

Problems we fix
Our experts diagnose and resolve any issue.
My steering whines when I turn
A whine that rises with the turn usually means the pump is working with low or aerated fluid. Sometimes that is a level and condition issue, sometimes the pump itself is going. Checking tells us which.
The wheel feels heavy at low speed
Assist falls off first where you notice it most, parking and tight turns. Degraded fluid, a low level, a slipping belt, or a failing pump can all cause it, so we check before replacing anything.
The fluid in the reservoir is dark brown
Dark, burnt smelling fluid means heat and wear, and the color often comes with fine metal suspended in it. That is the point where fresh fluid still helps, if the pump and rack are still in good shape.
The steering shudders at full lock
Holding the wheel all the way over builds pressure fast and heats the fluid quickly. A shudder or judder there can be fluid condition, but it can also be the pump relief or the rack, so it gets diagnosed.
I was told I need a power steering flush
First thing we do is confirm your vehicle even has hydraulic steering. If it does, we look at the fluid and tell you honestly whether it is worn enough to justify the service yet.
The reservoir keeps going low
This system does not use up fluid, so a dropping level means it is going somewhere. Hoses, the pump shaft seal, and the rack boots are the usual places. Finding the leak comes before adding more.

Common questions about our power steering fluid service services.
How do I know whether my vehicle has electric power steering?
The quickest way is to let us look, since it takes about a minute to spot the reservoir or confirm there is not one. Electric systems became common on newer cars and small crossovers, while trucks and older vehicles are more often hydraulic. Either way we will tell you what you have before we talk about service.
Is a power steering flush the same as a fluid change?
No. Emptying and refilling the reservoir swaps only part of what is in the system, since the rest stays in the lines, the pump, and the rack. A proper service moves the old fluid out and new fluid through. Which approach makes sense depends on your vehicle and how worn the fluid is.
Can I use any power steering fluid, or transmission fluid?
You cannot, and it is a common way to cause an expensive problem. Some vehicles specify a transmission fluid, some call for a specific power steering fluid, and the seals inside are built for one or the other. Putting in the wrong one can swell or shrink seals and start a leak.
Will new fluid quiet a whining pump?
Sometimes, if the noise is coming from low or broken down fluid and the pump is still healthy. If the pump has already worn internally, fresh fluid may quiet it briefly and the noise comes back. We would rather tell you which situation you are in than take the money and hope.
The level is low, should I just top it off?
Topping it off is fine to get you off the side of the road, but it is not the answer. A closed system that keeps dropping has a leak, and that leak is the repair. Bring it in and we will find where it is going.
