Go to the back seat of the 740 and pull the ash tray out from the rear of the front center arm rest. Unscrew the two Philips head screws that are underneath. Pull the center arm rest up and then back and place it to the side so that it does not get bent. Pull the emergency brake jacket off and the center plastic bezel from around the shifter.

Work the screwdriver in the seam between the center console bezel and the rest of the dash. Pull the center console bezel straight back and then up once all the pegs are disengaged. Place the center console somewhere safe, as it too is prone to cracking.

1. Remove the lower splash guard by turning its bolts in a counterclockwise direction. There are four bolts holding it in, and removing it will give bottom access to the power steering pump.
2. Drain the fluid from the pump by uncapping it and siphoning the old fluid out with a turkey baster or similar device. Fluid can be collected in a drain pan.

7. Replace the pump with the new one, reconnecting its lines and tightening the mounting bolts.
8. Replace the drive belt and tighten the tension pulley by turning its bolt in a counterclockwise direction. The belt should have about an inch of play.
9. Fill the power steering pump with fresh fluid by cranking the car and moving the steering wheel back and forth while pouring fluid into the pump. Do not overfill the pump, as the pressures inside of it are very high.

1. Buy a timing chain that is made specifically for the BMW 525i 2.5L engine. Most auto parts store or online vendors carry the timing chain needed. Lift the hood of your vehicle and disconnect the negative battery cable. Remove the vibration damper and hub assembly to reach the upper and lower timing case covers. Remove case covers. Refer to the vehicle service or owners manual to identify vehicle parts.

Reattach camshaft sprockets and tighten bolts using a wrench to 16 foot pounds (22Nm). Reattach and tighten lower timing cover bolts to 6.5 to 8.0 foot pounds (9 to 11Nm). Reattach the vibration damper hub bolt and tighten to 17 foot pounds (23 Nm).
4. Replace the upper and lower timing case covers. Start the engine to make sure the timing chain is installed properly.

1. Open your Mercedes hood so you can access the belt. Be sure the engine is cool before operating.
2. Loosen every bolt in the series that binds the belt into place. Take special care to remember the pattern in which the fan belt is attached. This is the same pattern youll follow to route the new fan belt. Do not remove the bolts, simply loosen them so that the belt looses tension at each point.
3. Pull the belt out of each connection, making sure you leave it intact so that you can compare it to the new belt.
4. Stretch the old and new belts out completely with both hands. Compare the size of each belt to make sure the new belt will fit your Mercedes engine.
5. Route the belt along each pulley, following the pattern you took note of when loosening the tension. Press down with a free hand after connecting the belt to each pulley so that you continuously create tension in the belt.
