Warning
When draining the steering fluid, the engine shall be
stopped before disassembling the tube connectors in BR
the system. Since the power steering oil pump is
at work status when engine is running, high oil BW
pressures exist in the tubes that may lead splash of the
fluid, causing unnecessary troubles. EL

oil return hose of the steering fluid tank with the oil
return steel tube assembly. Pull out the oil return hose.

the steering oil from the steering fluid tank into the oil
sump tank.
