Lubegard Power Steering Flush and Protect Pack is the perfect solution for noisy or stiff power steering systems. It is used by professional technicians worldwide. It is fast and simple, with immediate results. The power steering systems are generally only noticed when something has gone wrong. This system is one of the simplest to maintain and is also the most noticeable when something goes wrong. A power steering system is generally subject to harsh temperatures leading to fluid deterioration over time. Through constant use and high operating pressures, other types of wear materials are also generated that degrade the system. The result of this pressure and heat is fluid breakdown, contamination, loss of lubricating properties, and varnish deposits. When power steering fluid circulates throughout the system of pump and gear, it picks up wear material as well as contamination from the breakdown of aging hoses and seals. The periodic maintenance of this intricate and precise system is necessary. The directions for use without flush machine: open the power steering fluid reservoir and add one bottle of Lubegard power steering flush; do not overfill; with the vehicle in the park and the brake on, start the engine; turn the steering wheel at least 4 times all the way left and right; shut off the engine and remove the old fluid. To refill: open the power steering reservoir; add 4 fluid ounces (one bottle) of Lubegard power steering fluid protectant and top off with appropriate power steering fluid to proper level. Please refer to the vehicle manual for the proper fluid type. Do not overfill. Do not use in systems that use brake fluid.
