Looking for an engine layout or picture. Don't know what the square housing is above the power steering hose that I have to replace

NO ENGINE SIZE STATED so answers will be all wrong. see?
why not just read the free manual?
chapter "steering?"
FSM WJ, 1999 or near.
chapter 19? is steering .see page 7,
seen here, read that yet?

or at alldata.com

if you cant reach something
that means that the something must be removed first.
it should be obvious to you ,that.
remove pump first? (belt is first first but is obvious , no?)

use youtube and see 1000s to it.
ever do that? u tube.

OK you know the problem but is it something as simple as replacing the Power steering hose or as complicated as also needing a new power steering pump also? Look at where its leaking to determine what needs replacing. Remember it just takes a little time to determine where its leaking. If you find that its not the hose leaking but its the power steering pump then follow these easy steps and save $100s doing it yourself:
1 Remove the negative battery cable with a wrench and place it aside. Remove the upper strut housing tie bar if necessary for access. Remove the power steering serpentine drive belt and electrical plug on the TFE off as applicable. Remove the lower bolt from the mounting bracket using a socket and ratchet if necessary for access. Take off the inlet and outlet hoses from the power steering pump. Remove the reservoir hose only on the supercharged engine. You will need a flat-head screwdriver for this task.
2 Place the power steering pump pulley so the bolts can be accessed through the hole in it. Remove the mounting bolts, using a socket and ratchet, through the hole in the pulley. Take the power-steering assembly out from the bracket. If necessary transfer the pulley to the new pump with a pulley puller.
3 Replace the power steering pulley assembly before you install the pump using the pulley-install tool from your kit. Start the power steering inlet hose connection to the pump by hand. Replace the power steering pump assembly to the engine. Replace the lower bolt first, making sure the hose and heater pipe have enough clearance so they do not touch. If the two rub together they will make noise after the installation is finished. Replace the outlet hose to the pump, directing the hose under the engine harness and the heater hose. If the engine is supercharged it will be necessary to connect the hose from the reservoir.
4 Torque the power steering gear inlet hose to 20 foot-pounds and the hose clamp at the pump to 15 inch-pounds. Torque the pump mounting bolts to 20 foot-pounds. If equipped with a TFE pump, attach the connection. Replace the power steering drive belt or serpentine belt if you removed either. Replace the upper strut tie bar and torque the nuts to 18 foot-pounds. Replace the negative battery cable and fill the power steering reservoir with fluid. Bleed the steering system by starting the engine and turning the steering wheel right and left until all the air is out.

Hi Will, Look at the engine and follow the top radiator hose to the place where it enters the engine. Where it connects is the thermostat housing. The domed part is what you are looking for, but if you don't know what it is and what it looks like how do you know it needs replacement? Regards John

2004 KIA SORENTO Power Steering Pressure Hose HERE IS WHAT I FOUND LET ME KNOW HOW THIS WORKS FOR YOU.

Well don't know exactly what vehicle you are working on but it is very possible that if is a car then the inner seals on the rack-n-pinion are worn out causing the fluid to leak out. If it is the rack seals leaking then you will need to replace the rack-n-pinion. Good luck.

On 1996 VW JETTA,The thermostat is located at the engine end of the lower radiator hose (passenger side). If the car has power-steering, then power steering pump and mounting bracket are to be removed to get to the thermostat housing. The thermostat is at the end of the bottom hose, in the water pump housing. Follow the lower radiator hose to the water pump housing. There are three bolts that are very difficult to navigate around. The thermostat is located behind those bolts.
----------------- Thank you.

THE P/Steering layout is from P/S/Pump the hose goes to the Rack and pinion and then the other hose returnes to the pump .

determine this by looking to see if the coolant line leads to the transmission (bell housing made of aluminum in general) or it leads to the power steering pump (belt driven)

CYLINDER HEAD REMOVAL

2.5L Engines

1. Before servicing the vehicle, refer to the Precautions Section.
   
2. Drain cooling system and engine oil.
   
3. Relieve the fuel system pressure.
   
4. Remove or disconnect the following:
   
   • Negative battery cable

   • Timing chain
     
   • Drive belt tensioner
     
   • Camshafts
     
   • Spark plugs
     
   • Exhaust manifold
     
5. Support the engine from above and below with a suitable jack and hoist.
   
6. Remove or disconnect the following:
   
   • Power steering pump and reservoir and wire aside
     
   • Auxiliary drive belts
     
   • A/C compressor and wire aside

7. Loosen the cylinder head bolts in the sequence shown and remove the cylinder head.
   

Removing the front suspension member—Altima


Cylinder head bolt removal sequence—2.5L engine–Altima and Sentra


Cylinder head bolt tightening sequence—2.5L engine–Altima and Sentra

To install:

1. Clean the gasket surfaces.
   
2. Using new head gaskets, install the cylinder heads.
   NOTE If possible, replacement of the head bolts is suggested.
   
   
3. If replacement of the head bolts is not possible, perform the following bolt measurement:
   
   • Measure the diameter of the head bolt 0.43 in. (11mm) from the bottom of the bolt.
     
   • Measure the diameter of the head bolt 2.17 in. (55mm) from the bottom of the bolt.
     
   • Whenever the size difference between the 2 measurements exceeds 0.0091 in. (0.23mm) the head bolts must be replaced.
     
4. Apply clean engine oil to the bolt threads and seating surfaces and tighten the cylinder head bolts in sequence as follows:
   
   • Step 1: 72 ft. lbs. (98 Nm).
     
   • Step 2: Loosen all the bolts completely.
     
   • Step 2: 29 ft. lbs. (33 Nm).
     
   • Step 4: Plus 75–80 degrees clockwise.
     
   • Step 5: Plus 75–80 degrees clockwise.
     
5. Install the front suspension member and tighten the bolts to the specifications shown in the illustration.
   
6. Install or connect the following:

   • Engine undercover
     
   • Right side fuse/relay box and move aside
     
   • Upper radiator hose and heater hose
     
   • Negative battery cable
     
7. Fill the cooling system and engine oil
   
8. Start the vehicle, check for leaks and repair if necessary.
   

This is what it looks like:


THERE IS NO CAP TO FILL IT LIKE NORMAL POWER STEERING SYSTEMS. IT HAS TO BE SERVICED FROM THE INLET HOSE.

1. Fill pump with hydraulic fluid through intake line. Turn the pulley/shaft by hand until fluid comes out of pressure port.

Look underneath the car up at the driver's side of the car above your tie rods (or look at it from above). It is mounted to your steering gear.
