Checking and topping up the power steering fluid Mercedes-Benz Vito II W639 2003 - 2014

Parts and consumables:

• Power steering fluid
• Rags
• Funnel (if necessary)

Notes:

We check the fluid level in the power steering reservoir at every maintenance, as well as when a fluid leak from the power steering hydraulic drive is detected, when the steering efficiency decreases or extraneous noise (howling) appears when the steering wheel rotates.
It is important to determine the location of the leak as accurately as possible, as this will most likely require replacement of a worn or damaged part.
