Description:
Power steering systems have two
hoses—a high-pressure hose and a low-pressure hose. The high-pressure hose
is made from a reinforced synthetic compound and the hose
fittings are usually double-flared compression fittings. The low-pressure hose is similar in
construction, but it may not use compression fittings due to the lower pressure in this hose.
Purpose: The high-pressure (supply)
hose carries high-pressure oil from
the power steering
pump to the steering gear. The low-pressure (return) hose
carries oil from the steering gear back to the pump or
its reservoir.
Maintenance Tips/Suggestions: Check the power steering fluid level at
every oil change and inspect the hoses regularly. When checking the
hoses, look for leaks, rusted or corroded fittings,
sponginess, stiffness, and cuts and abrasions. Hoses showing any of these conditions should be
replaced. Refer to your car’s owner’s manual for specific recommendations on the
type of power steering fluid to use. Fluids need to be
compatible with hoses and seals and in some cases the recommended fluid may
be automatic transmission fluids such as Type F or Dexron®.
It’s possible to check the power steering fluid level when your car
is cold, but it’s usually recommended to check the fluid with the car warmed
up. Many cars today use a semi-transparent
reservoir for power steering fluid, so look for a fluid level
mark on the outside. If the reservoir has no markings, open
the reservoir's cap. There should be a small dipstick attached that
provides the level reading. Use care not
to run the system low on fluid; insufficient fluid level
can damage the power steering pump.
