Whilst the photo's in this thread are taken of a 1996 E36 325tds the 6 cylinder models are all quite similar and will use the same principal.
Before you commence any work on your vehicle PLEASE compare this thread to the vehicle you will be working on and ensure everything looks correct
The first thing you will need to do is remove the ancillary belt otherwise known as the V-belt . In order to do this you will need to release the pressure from the belt tensioner.
(PLEASE DRAW A DIAGRAM OF THE ROUTE THE BELT TAKES TO AID REFITTING)
DO NOT UNDER ANY CIRCUMSTANCES REMOVE THE BOLT THAT SECURES THIS THROUGH THE HEAD!!!:jaw-dropping:jaw-dropping:jaw-dropping
In order to release the pressure you will need a ratchet and Hexagonal key. Turn your ratchet in a clockwise movement.
The belt will slacken enough for you to remove the belt from a pulley. Once the belt is free release the pressure on the tensioner.
Now that the belt has been removed you can start removing the pump.
This is where it's going to get messy
I removed the power steering reservoir cap and plug from the bottom of the power steering pump and drained all of the fluid.
PLEASE DISPOSE OF YOUR WASTE OILS IN THE CORRECT MANNER
Once the oil had drained I removed the two bolts that secure the power steering pipes into position.
I then tucked the pipes out of the way and wrapped them with paper towel so that I would not get dripped on whilst laying under the car.
There are four bolts that secure the pump to the bracket that attaches to the engine.
The two bolts on the rear of the pump are easy to remove
The two on the front are not so easy as they are behind the pulley
Now that the belt has been removed it becomes rather difficult to remove the pulley securing bolts and keep it from spinning. Unfortunately I can't remember how I stopped the pulley from spinning
You will probably find that the pulley will not just pull off. Gently tap the outer edge of the pulley with a rubber/Hyde mallet to (prevent damage) whilst rotating the pulley so that you are not hitting the same point each time and it comes off evenly.
Once the pulley has been removed you will see the two remaining bolts that secure the pump to the bracket
Undo the two bolts and the pump unit is ready to be removed. You may need to pry it out with a pry bar or screw driver
Once the pump unit is out it will look like this
REFIT IN THE REVERSE ORDER ensuring that the correct torque settings are used on each bolt
To bleed the power steering fluid through I filled the reservoir with POWER STEERING FLUID. I then started the engine and let it idle.
Looking back into the reservoir showed up loads of tiny bubbles that make the clear fluid seem cloudy.
When it looked like the bubbles were settling I rocked the steering gently from side to side for a couple of minutes. After that I did the same but turning the steering wheel more. I finally rocked the steering from lock to lock and then after a couple of minutes of doing that I rocked from lock to lock with a brief hold on the lock.
with the engine still running I checked the fluid was clear of bubbles and re-secured the reservoir cap.
Hope this helps
PS If anyone has a better method of carrying out this task, please feel free to post your comments in this thread
