If you’re like most drivers, you probably don’t think about your car’s power steering fluid (PSF) until it starts to make noise or perform poorly. But if your car doesn’t have enough PSF, it can cause serious problems, such as a hard time turning, reduced driving range, and even a potential crash. So what is PSF, and should you be filling up your car’s reservoir regularly?
What is Power Steering Fluid
Power steering fluid is a fluid that is used in power steering systems. It helps to provide a smooth and consistent flow of power to the steering wheel, making it easier for the driver to control the car.
A power steering system includes both the power steering pump and the power steering fluid. The pump sucks air from the engine and forces it through the system, pushing the fluid along with it. The fluid helps to turn the gears inside the pump, providing the necessary force to keep the car moving in a straight line.
The power steering fluid should be replaced every 3 to 5 years, depending on how often you use your car and how much road abuse it sees. When diagnosing a power steering issue, always check for signs of an oil leak (see below) and make sure that your power steering system is properly lubricated.
Types of Power Steering Fluid
Power steering fluid is made up of many different chemicals that work together to help your car move in the right direction. It helps to keep your car moving smoothly and helps to keep the power steering system working properly.
There are three main types of power steering fluid: synthetic, mineral, and hybrid. Each type has its own particular benefits and drawbacks.
Synthetic power steering fluid is the most common type and is made up of a variety of different chemicals that work together to improve performance and durability. It is also the most expensive type of power steering fluid.
Mineral power steering fluid is made up of natural minerals like potassium phosphate. This type of power steering fluid is cheaper than synthetic power steering fluid, but it doesn’t have as many benefits. Mineral power steering fluid can cause build-up on the seals in the power steering system, which can eventually lead to a failure.
Hybrid power steering fluid combines both synthetic and mineral elements for improved performance and cost-effectiveness.
How to Check if Your Car Needs Power Steering Fluid
In case you are wondering if your car needs power steering fluid, here is a guide on how to check.
First, make sure all of the car’s fluids are full and at the correct levels. Next, start the engine and let it idle for a couple of minutes. Then, use a fluid level tester to measure the reservoir level and see if there is any need for replacement. If there is a need for power steering fluid, then you will need to replace the reservoir as well as the fluid.
How to Replace Power Steering Fluid in a Car
If your car’s power steering doesn’t seem to work as well as it used to, it might be time to replace the fluid. This is a relatively easy job that can be done by anyone with some basic mechanical skills. Here’s how to do it:
1. Park your car in a level location and turn off the engine.
2. Remove the hood and front bumper (if they’re attached).
3. Locate and remove the power steering fluid reservoir. It will likely be located behind the front of the engine near the firewall.
4. Remove the old fluid with a turkey baster or siphon tube. Be sure to discard the old fluid!
5. Pour a new batch of power steering fluid into the reservoir using a funnel or syringe, making sure to fill it to the top of the container. Replace the cover and tighten bolts with a socket wrench.
6. Reinstall the hood and front bumper, if necessary, and start your car up!
