Power Steering Fluid
Power steering fluid transmits pressure in hydraulic power steering systems.
What is Power Steering Fluid?
Types vary, including ATF and special fluids. The reservoir has level marks. Electric systems do not use fluid. Fluid that is dark or smells burnt has degraded and can damage seals. Some manufacturers specify a change interval while others consider it lifetime fluid. Mixing incompatible fluids, such as mineral and synthetic types, can damage seals. Foamy fluid indicates air in the system, often from a loose hose or low level.
How it works
The pump pressurises the fluid to assist steering.
Why it matters for your car
Low fluid causes whining and heavy steering. Use the specified fluid.
