## Description

A special additive in the power steering fluid to prevent and eliminate leaks from the steering system. Eliminates power steering, pump, and steering rack leaks, significantly extending their service life. With regular use, it increases the service life of the system by 1.5 - 2 times. Application: Stop the engine. Drain the liquid from the hydraulic pump tank completely or partially (depending on the type of tank). Fill the tank with an equivalent amount of power steering fluid by adding MANNOL Power Steering Leak-Stop. The contents of the bottle are enough for 3 liters of liquid. The power steering fluid must be checked regularly and changed at the recommended intervals.

Review: My old Santro had a leak and I used to refill steering oil every week. This leak stop did the work and stopped the leak in 3-4 days. Good performance, value for money. Whole bottle is sufficient for 3 liters, so use appropriately as required.
Review: Alles ok!!
