Good day , may I request for a power steering diagram? I have a leak in one of the lines if not more then one line. Preferably pressure hose and return hose.
Thank you

I am attaching the diagrams for the pumps that are available for this vehicle. It is either the 2AZ-FE pump or the 1MZ-FE pump. I believe the 4 cylinder engine gets the 1MZ-FE but you should be able to compare the layout/diagram to what you have just to be sure.

Thanks.

Thank you, thank you.
I will figure out the correct diagram but at least I know what to look for.
By the way, the return hose, would you happen to know where that would be located?
I see the pressure hose so I'm thinking the return hose also comes out the pump, yes?

I am sorry. The 4 cylinder engine is the 2AZ-FE diagram.

As for the return line, that does not come off the pump. The flow through the system is it goes from the reservoir to the pump, from the pump to the rack and pinion as high pressure, from the rack back to the reservoir.

So in the attachments, the pump has a number 1 and 2 in red that I added. Number 1 is the pressure line going to the rack. Number 2 is from the reservoir to the pump.

The second attachment is number 1 is from the pump to the rack (pressure line). Then number 2 is from the rack back to the reservoir.
