The Best Power Steering Stop Leak Additive

Steering your car is something you probably never put a second thought to. Yet, lurking beneath the surface is a network of pipes, pumps and fluid lines working away, to take your inputs from the steering wheel to the road. Without power steering, turning the steering wheel would require you to use some serious muscle. Power steering may have been fitted to cars for decades, but even now it is by no means bullet proof.

Over the years, miles and thousands of turns the power steering components and seals will wear and loosen. This will inevitably create leaks in the system and, no matter how small, will begin to create issues with the vehicles steering components. Besides having to replace fluid and damaging the environment with hazardous chemicals, you also run the chance of getting dirt into the power steering system and causing expensive damage.

Stopping leaks is helpful for day-to-day driving while also being important for MOT tests, as a power steering leak is a guaranteed failure if spotted by the testing technician.

Noisy power steering will also become a thing of the past, as seals and O-rings become better lubricated and allow efficient function of the steering system in your vehicle once again. Any of the products below are suitable to solve power steering leaks and help prevent future problems arising.
