Checking your power steering fluid level is straightforward, but if you are unsure, always refer to your vehicle’s manual. The first step is locating your power steering fluid reservoir cylinder. It is usually located close to the power steering pump. In some vehicles it is located with the pump hoses, however, in either case, it should be made of either metal or plastic and have a clearly labeled cap.
Once you have located the cylinder there are two ways to check the level of the fluid. Some cylinders are translucent, meaning you can see through the material and check the fluid level against the minimum and maximum levels that are indicated on the cylinder itself. Remember that you will still need to open the cylinder to check the color and smell of the fluid, and to check for debris.
Where you cannot see through the cylinder, you will need to use a dip stick. Most vehicles have a dip stick attached to the underside of the cap to make this process easier. The dip stick will contain markings for minimum and maximum fluid levels.
However, it is important to note that to gain an accurate reading in some vehicles, you need to run the engine for a brief period, and even turn the steering several times in either direction while the car idles. If you are unsure whether this is the case for your vehicle, check the vehicle’s manual.
Other vehicles provide two sets of markings or graduations on the cylinder or on the dip stick. One set is for when the engine has been running and one for when it has been ideal. These may be marked as hot and cold. It is important to differentiate between the two sets of minimum and maximum markings to ensure you do not get a false reading. Again, if you are unsure, check your manual.
If your fluid levels are low, then check for a power steering fluid leak before going any further. If there is nothing wrong with the fluid and there are no leaks in the system, then you can top up your fluid to the correct position and replace your cylinder cap. If there are any issues with the fluid, then it should be changed to reduce the risk of damage to the pump and other elements of your power steering system,
