Power steering line diagram needed?

Hello ROBERT, CLARK2,

It looks like the pressure line for the power steering runs right in that area. It is a combination of a metal line and flexible hose. It runs from the pump straight to the rack.

I will add a diagram for you.

I found a part number from Motorcraft, Fords value line, which comes with all the seals you will need as well.

Part number: 7S4Z3A719B

You can go to the dealer for it, or Rock Auto may have it as well.

In case you need it, the fluid is just Motorcraft Mercon V.

The pressure switch may not come with it (marked in green). If it doesn't you will need new O-rings for that.

Removing the battery and battery tray will help give you some room.

I will add some instructions on how to replace the pressure line and removal of the battery tray from my information.

The instructions have you remove the power steering pump pulley, but I would look and see if you can get a wrench on it without removing it to save to some time. If you need to remove it a 2-jaw puller might work but I would use a power steering pump pulley puller, say that ten times fast lol. You can rent one at an auto parts store.

I would use a little bit of new power steering fluid on each O-ring to avoid them tearing and help them slide in.

To bleed the system just fill the system up when line is replaced, and vehicle is still on jackstands.

1) With the car off, turn wheels lock to lock slowly while an assistant watches for bubbles at the pump and adds a little fluid at a time.

2) Once no more bubbles are seen, top off the fluid and start the car and turn steering wheel lock to lock slowly while an assistant watches for bubbles and add fluid as needed.

You may need to repeat this a couple times especially if the pump starts to make noise.

Make sure as you are filling you are watching for leaks.

Let me know if I can help you with any other information.

You said Mercon v. Isn't that trai fluid? Like I heard you can use it if there's no power steering fluid but shouldn't power steering fluid go in first and foremost?

Hello ROBERT CLARK2,

Some take power steering fluid others just use transmission fluid for power steering. In my opinion you should always put in what the manufacturer recommends when changing fluids. Dexron, Mercon, ATF+4, Type F and others are used by manufacturers as power steering fluid.

Sometimes a system can also take one or the other. But the 2 should never be mixed.

I added the fluid chart for you from my reference manual.

Thank you,
Brendon
