Fix the hood in the open position, for which, acting simultaneously on both sides, lift the locking brackets, simultaneously moving them upwards, and disconnect the dampers from the hood. Open the hood completely, install the devices "51.2.170" (Fig. 6.31) on the dampers and fix the hood with them.
Drain the coolant and remove the radiator of the cooling system and the coolant supply hoses. Remove the intake manifold. Disconnect the engine wiring harnesses from the control electronics compartment and the body, move them to the side.
Remove the power steering pump, set it aside and secure it with a wire clamp in the engine compartment. Do not disconnect the pipes. Remove the vacuum receiver from the body, leave the pipes connected.
Disconnect the fuel lines from the high-pressure pump (HP) and the vacuum line from the brake booster. Remove the protective panels of the underbody, the engine compartment screen and the front panel of the protective crankcase of the BMW X5 E53 engine.
Loosen the clamps (1, Fig. 6.32), remove the hoses (2 and 3) connecting the supercharger radiator and its pipelines.
Remove the stiffening plate by unscrewing the bolts (1 and 2, Fig. 6.33).
Attention! Driving the car without a stiffening plate is strictly prohibited. The stiffening plate is secured each time with new boots and nuts, which must be tightened in two stages, first with a torque of 56 N·m (5.6 kgf·m), then by turning it to an angle of 90°.
Disconnect the exhaust system from the exhaust manifold, remove the gearbox and front wheel drive shafts. Remove the alternator and air conditioner compressor drive belt. Remove the air conditioner compressor from the support bracket, move it to the side and secure it to the body with a wire clip. Leave the pipes connected.
Disconnect the vacuum line (2, Fig. 6.34) from the engine mount cushion and remove the jumper between the engine and the body.
Install the device "11.0.020" (Fig. 6.35) on the lifting device (hoist, crane, lift). Install the rigging (chains of equal length) and hook them onto the engine lifting eyes. Raise the engine so that the chains are slightly taut.
Attention! After replacing the ground tires, the nuts must be tightened before installing the gearbox.
Loosen the nuts of the ground bus on the engine support brackets on the left and right sides. Once again make sure that the engine is not connected to the engine compartment of the car in any way, and carefully remove the engine.
The engine installation should be carried out in the reverse order, while it is necessary.
Tighten the nuts on the engine mount brackets immediately after installing the engine, since the engine may slip off the mount cushions when installing the gearbox. Nuts (9, see Fig. 6.36) tighten the bracket fastenings to the engine with a torque of 38 N·m (3.8 kgf·m), the cushion to the side member - 56 N·m (5.6 kgf·m) and the bracket to the engine - 42 N·m (4.2 kgf·m), after completing the installation of the engine, check their tightening.
Before installing the boost air hoses, make sure they are clean and dry; if necessary, remove traces of moisture and grease with alcohol. Tighten the air duct hose mounting screws to a torque of 6.0 N·m (0.6 kgf·m).
