2007 XC90 V8 power steering pump replacement

[Pretribrapper]

Please help. I have had a power steering pump with an air leak for about two years and it is finally starting to get noisier. The leak was minimal and I would add fluid twice a year. Car used to only make noise when first started cold and occasionally while driving slow and turning there would be a chirp. Ps fluid is now leaking out by actual ps pulley and I have a replacement pump but no idea how to do. Can someone please help point me in the right direction to a video or step by step guide? I am not finding any great resources online.This is the V8 4.4l motor.

Do you have VIDA? There's a good step-by-step guide in there. The key is that you have to take off the top half of the intake manifold to get the pump out. Basically, the steps are:

1. Remove the PS reservoir, drain the fluid.
2. Remove the top part of the intake manifold. (You will need 2 new gaskets for this.)
- disconnect wires from pressure/temp sensor (back left corner)
- disconnect 2 vacuum hoses from the check valve of the distribution damper
- remove 2 coolant hoses, 1 from throttle body and 1 from coolant distribution pipe
- might need to remove PCV valve and/or hoses
3. Remove the Auxiliaries Belt
4. Remove the power steering pump
Remove:
- Bolt to the pressure pipe
- Pressure Pipe
- hose from reservoir to pump
- 3 screws from the front of the PS pump
(I recall there being screws in the back of the pump too, although the instructions don't indicate so. There may also be a bracket that goes down to the lower intake manifold to remove.)

Installation is the reverse. Get a new o-ring for the pressure line. Pressure line is torqued to 32 Nm.

You may or may not need to remove the upper motor mount. The procedure says you need to, but the procedure is for the upper and lower intake manifold. You may not need to remove the motor mount for just the upper part.

I hope this helps - let me know if you need more detailed info.

You should download VIDA if you can. Here is an online workshop manual; it's a little fiddly, but may help some; click off the pop-up on the body of the page underneath or share, donate or whatever to make it go away

Using the menu on the left, you can go to Engine>Intake manifold etc. to get started

Or look on here or the other forum classifieds for a VIDA/DiCE for sale; you just need the VIDA for the info, though.
