Additive for the care and sealing of hydraulic power steering systems – reduces noise, seals small leaks and protects the power steering pump from wear.
Power Steering Protection & Leak Stop – Smooth Steering, Reliable Sealing & Long-Term System Care
The Power Steering Protection & Leak Stop by AUTOGAR® is a high-performance hydraulic additive designed to care for, protect, and restore power steering systems. Over time, seals harden, hoses become porous, and the steering pump experiences increased friction – leading to noise, stiffness, vibrations, and in many cases, small but persistent leaks. This advanced formula addresses all these issues directly, ensuring your steering remains smooth, quiet, and responsive during every drive.
Developed specifically for hydraulic power steering systems, this additive provides immediate improvement in lubrication, reduces noise during slow or tight maneuvers, and restores lost steering comfort. At the same time, its sealing technology works from the inside out: porous or hardened seals regain elasticity, micro-cracks are sealed, and fluid loss is significantly reduced. This prevents the system from drawing in air, which is one of the main causes of jerky steering and pump wear.
How Power Steering Protection & Leak Stop Works
With powerful conditioning agents, the additive penetrates deeply into rubber and elastomer seals, revitalizing them and allowing them to seal properly again. This regeneration effect is crucial for older systems or vehicles showing the first signs of power steering leakage.
By improving lubrication within the hydraulic circuit, friction inside the steering rack and pump is reduced, resulting in a quieter and more refined steering feel.
Additionally, the formula stabilizes the hydraulic fluid by preventing foaming, a common issue that leads to inconsistent steering response and pump cavitation. With improved fluid stability, the entire system operates more efficiently, even under heavy steering loads or during extended driving.
Restore Steering Comfort & Protect Your Pump
Drivers will notice benefits quickly: less noise when turning the wheel, smoother rotation at low speeds, and a more direct steering response. In cases where stiffness appears during cold starts or after long periods of driving, the additive helps restore normal operation by improving internal lubrication and reducing mechanical resistance.
By lowering friction and preventing metal-to-metal contact, the Power Steering Protection & Leak Stop also prolongs the service life of the power steering pump – one of the most expensive components in the hydraulic system. Used regularly, it helps maintain system cleanliness, protects seals from further aging, and keeps the entire steering assembly performing at its best.
Ideal for Leak Prevention & System Maintenance
This product is suitable for both symptomatic treatment and preventative maintenance. Whether your vehicle already shows early signs of leakage or you simply want to protect the system from future wear, the additive ensures smooth, reliable steering performance for many thousands of kilometers.
