Nulon 2 in 1 Power Steering Fluid with Stop Leak (PSFSL) has been specifically formulated to stop or minimise fluid leaks and maintain optimum performance of power steering systems. This power steering fluid contains seal swell additives that rejuvenate hardened or shrunken seals to prevent further leaks. One treatment stops most leaks.

Power steering systems are generally very reliable and failures are rare, so preventative maintenance is often neglected. Manufacturers rarely mention power steering maintenance in their service schedules. A little preventative maintenance goes a long way to ensuring trouble free operation. Inspections should be carried out at each service. Fluid level should be checked and the fluid should also be checked for cleanliness. If the fluid is dirty it should be changed, as dirt and sludge are major threats to smooth operation. Also, drive belts should be checked for condition and correct tension. Pulleys, mounting brackets and hoses should be checked for condition as well.

Power steering systems typically contain only a small volume of lubricating fluid, and that fluid is subjected to quite harsh conditions, particularly heat, moisture and contamination. Removing old, dirty and degraded power steering fluid and replacing it can extend the life of the entire power steering system. Use Nulon PSFSL for preventative maintenance. Its additional cleaning detergents maintain the durability and integrity of the power steering unit.
