You might be surprised to learn that there are a few different ways you can check your power steering fluid. While most people think you should do so with the engine off, some mechanics actually recommend checking it with the engine running.
What is power steering fluid?
Power steering fluid is a hydraulic fluid that helps to transmit the power from the steering wheel to the wheels of a vehicle. The fluid also helps to keep the steering components lubricated and cooled. When checking the power steering fluid, it is important to do so with the engine running. This will help to ensure that the fluid is at the correct level and temperature.
Checking the power steering fluid level
If the power steering fluid level is low, it could mean there’s a leak. To check the power steering fluid level, first find the power steering reservoir. On most cars, it’s located near the engine bay on the driver’s side. Once you’ve found it, remove the cap and look at the fluid level. If it’s low, add more power steering fluid until it reaches the “full” line on the reservoir.
How to add power steering fluid
Adding power steering fluid to your car is a pretty simple process, but there are a few things you need to keep in mind. First, make sure that you check your power steering fluid level with the engine off. The reason for this is because the fluid level will be different when the engine is running.
If you add fluid when the engine is running, you run the risk of overfilling the system and causing damage. Second, use only the type of power steering fluid specified by your car’s manufacturer. Different types of fluids can cause damage to the system.
To add power steering fluid, simply open the hood and locate the power steering reservoir. Remove the cap and slowly pour in the new fluid until it reaches the “full” line on the reservoir. Replace the cap and close the hood.
Signs of a power steering fluid leak
If you notice any of the following signs, there may be a power steering fluid leak in your car:
1. A whining noise when you turn the wheel.
2. Steering that feels stiffer than usual.
3. A dashboard warning light that comes on.
4. Fluid leaking from under the hood of your car.
Conclusion
As a general rule, you should always check your power steering fluid with the engine off. However, there are some exceptions to this rule. If you have a leak in your power steering system, it’s best to check the fluid level with the engine running so you can identify the source of the leak. Checking the fluid level with the engine running also allows you to see if there is any air in the system, which can cause problems.
