the best way that i can think of is by getting a second person and get them to start the engine and turn the steering wheel slowly while you check to see where it is leaking from (make sure there is Power Steering fluid in the pump)
Look at the under carriage and check the ground where the vehicle is parked for a power steering puddle or stain.
Clean the power steering are real good check for where the leak is coming from and go from there. For example if a hose is leaking replace hose, if power steering pump seals are leaking replace pump, exc.
Power steering hoses can be replaced if they leak.
How do you troubleshoot a power steering leak on a 1993 Lexus ES300?"
Check your hoses from the power steering reservoir for cracks in them and also check the power steering rack on the firewall to see if the rubber seals on the ends of the rack are leaking, maybe the reservoir itself is leaking, have it checked out.
Check to see where leak originates could be: Leaking pump seal Leaking high or low pressure hose Could be steering rack
it is very dangerous to drive with a power steering leak. This is because steering can become almost impossible and you could have an accident.
will a power steering cap leak
No, but impossible to check anything else if it is leaking. And if the rack and pinon is leaking, then it will have to be changed anyway.
Most likely a problem with the power steering pump or a power steering fluid leak. Check the power steering fluid is at required level. (Power steering fluid dipstick check should show between the Hot and Cold marks with engine running.) HTH, Red
Yes
The cost of a power steering leak repair depends on the leak placement and the car. A filler cap replacement might be 5.00, while a leak causing a steering rack replacement could be 750.00 or more.
