Penrite Power Steering Stop Leak 375mL Penrite Power Steering Stop Leak has been specifically formulated to control leaks in the power steering system due to deteriorated or worn seals and gaskets. Power Steering Stop Leak has been designed for use in power steering systems that utilise Automatic Transmission Fluids (ATF's) as the power steering fluid. It is suitable for passenger cars, 4WD's, and light commercial vehicles Power steering is a standard fixture on all cars today and with the continued efforts of car manufacturers to cram engine bays with more and more components it usually ends with the power steering pump tucked somewhere deep and inaccessible making it difficult to change easily. This means that if your power steering pump is on the way out it can be quite the costly exercise to have it replaced. Repco stock a range of quality brand name power steering stop leaks and conditioners to ensure you can gain maximum mileage from your power steering pump and rack and have the peace of mind to continue motoring. Many of the stop leak products in this range help in reducing slack, squeals and can correct hard spots in rack and pinion steering and are designed to soften seals and gaskets that can prolong the life of your rack and pinion system.
