87 Toyota
Supra Turbo, Power Steering Maintenance
Q: I have read that changing the power steering fluid and installing
a filter are rather easy and affordable ways to prolong the life of a
power steering system. If this is the case how do you change the fluid?
How do you install the filter? I have a 1987 Toyota Supra Turbo and I
am very eager to find out the answers to these questions. Thank you for
your consideration.
A:You’re
right; regular changing of the power steering fluid in your vehicle will
extend the power steering assembly’s useful life. You just reminded
me that two of my own vehicles are overdue for service.
Changing
the power steering fluid is a simple procedure. There is a return hose
from the power steering rack that enters a reservoir for the power steering
system. The first step is to remove this hose and direct it into an oil
catch pan. Be sure to block the return hose fitting on the power steering
reservoir. Have an assistant start the engine and turn the steering to
the right and left. At the same time pour power steering fluid into the
reservoir to maintain its level, preventing air from entering the power
steering system.
Watch the
oil that is flowing into the oil catch pan. Once this oil appears to be
to as clear as the oil being poured in, turn the engine off and reconnect
the return hose to the reservoir. Restart the engine and check the oil
level and inspect for leaks.
As for a
filter for the power steering system, I’ve not seen any that I believe
are worth installing. Regular flushing of the power steering system with
good quality oil is all that should be needed.
Note: Not
all vehicles take the same type of power steering fluid (oil). Be sure
to check your Owner’s Manual for the correct power steering fluid
for your application. Failure in taking this step can cause very expensive
damage to the power steering system.
