I have a ES300 - 1993 - V6 - Automatic. I have a leak on my power steering systems and it is coming from some sort of valve or sensor, which appears to be threaded into my Power Steering pump. I cannot find this part anywhere, although I have reached out to a dealership. Does anyone know if it is available online, and if so what is it called, and who has it. any help would be great!! Thanks

Are you certain the leak is coming from the hydraulic valve? There are two O-ring maybe one is leaking. Here are the part numbers.

Hydraulic valve - 16929-62020
O-ring inner - 90301-14002
O-ring outer - 90301-25005

You can get a rebuilt pump for $180, that's about the same price as the valve at the dealer.

Dealership parts guy tells me: "it looks like part 44308 is what you are needing if you can see if that looks like it and let me know. I can get you a price."

I have looked at various pumps, and do not see that part as included.

Thanks for your input . . I need to get this sorted out.
