hi from france
lexus ls 400 1990.
i change my power steering liquid every month. Because every month there is a noise like air in the system. It's tired to do this every month. I hope there is something else whose wrong.
thanks all guys for your answers and questions on this forum.
We love our cars.
i have answers to all these powersteering issues, first off if u r getting smoke at start up it is the valve on your pump, it has 2 vacuum lines going to it and one goes to the intake manifold
next ......if u replace one component of the power steering you need to replace hoses and the rack, contaminated fluid will kill one and cause the others to fail, if u plan on keeping your car fix it and fix it right do not do this job half assed, other wise u will be replacing components later on 2 or 3 times until u have them all fixed anyways, i have fixed just about everything on my 92 so any questions any of u have u can email me, i work for NAPA auto parts and used to be a mechanic, i have extensive knowledge and would like to help on any situation i can
