Power Steering Fluid Sealer: How it Helps

How a Power Steering Fluid Sealer Stops Fluid Leakage

Many vehicle owners who find that the power steering fluid is leaking are told that a Power Steering Fluid Sealer is a quick and effective way to end the leakage. However, if the user wishes to use the sealer properly, he should first understand how the sealer prevents leakages from the power steering system. The vehicle user should also be aware that the sealer is effective in only stopping certain kinds of leaks of the steering fluid, there are many other leaks which cannot be fixed using the sealer. Hence, the vehicle user should first try to diagnose the cause of the leakage.

Rubber Components

Vehicle users and owners should be aware that the Power Steering Fluid Sealer is mainly effective in stopping leaks due to rubber parts like seals, hoses, gaskets and O rings in the power steering system. In a new vehicle, these rubber parts are soft and fit perfectly, ensuring that there is no gap through which the fluid can leak. After the vehicle has been used for a few years, the fluid will often partly evaporate, and the rubber parts will shrink and become dry. This can result in gaps in the seals, hoses and gaskets, through which some of the fluid will leak, adversely affecting the power steering performance.

Effect Of Sealer

Every vehicle owner should try to understand how the Power Steering Fluid Sealer affects the various components of the power steering to end the fluid leakage. The sealer has a number of chemicals and additives which are selected mainly because of their ability to act on rubber parts like gaskets, seals, hoses, make them soft and elastic. These rubber parts will again expand to their original size, and close any gap, preventing any further leak. The sealer will undo some of the damage caused by the wear and tear. Some sealers will also form a film around the seal or rubber part to close any grooves or holes.

Usage Tips

The Power Steering Fluid Sealer will only be effective if it is used in the right way. Each vehicle has a reservoir for the power steering fluid, and additional fluid can be added, if the levels are lower than the specified levels. The reservoir usually has a cover, and the vehicle owner, should check the levels manually. The sealer fluid should be added to the reservoir just as the steering fluid is added. Most manufacturers are supplying bottles of the sealer fluid, and they claim that one bottle is enough for a standard size car, jeep, van or smaller truck.


The effectiveness of the Power Steering Fluid Sealer depends to a large extent on the brand of sealer being used and the extent of leakage. If the leakage is less, the improvement due to the addition of the sealer could be visible within one hour in some cases. However, most sealer manufacturers claim that it will take at least forty eight hours for the sealer to have the desired effect. It will take some time for the fluid to circulate through the seals and gaskets of the power steering system, to make them pliable and form a film. In some cases, adding another bottle of sealer to the power steering may help. If this does not work, it is better to contact a mechanic.
