Removing and installing
The power unit consists of an engine and gearbox. Shoot it using the hydraulic lift or hoist, dropping from the engine compartment. Before removing the power unit, do the following: - If the car has an alarm system with security code, the code is necessary to have at itself, to turn the system on after connecting AB; - When removing the engine will need to disconnect a large number of electric wires and vacuum hoses and coolant hoses. Before removing wires and hoses tag them using tags; - Before the assembly work in the engine compartment must be closed with a thick cloth front wings of the car. Removal of the power unit in the following order: - Turn off the engine and remove the ignition key; - Disconnect terminal "-" of the AB;
A warning In order to avoid damage to the computer, you must disconnect the terminals AB only with the ignition off. And for a complete ignition is switched off wait at least 20 seconds and only then you can disable the "-" terminal of the AB. |

- Disconnect the spring clamp holders 14 fuel (see. Fig. 26) supply and discharge of fuel; - Mark the fuel hoses and disconnect the supply and removal of fuel from the fuel distributor;
A warning The fuel lines are under pressure. Before disconnecting the fuel hose from its mounting, grasp the point of attachment of the fuel hose thick cloth, and gently pulling it to the site of attachment, release pressure in the system. |
- Disconnect the plug connector with a large 42 connectors located in the vicinity of the ignition coil; - Disconnect the vacuum hose brake booster; - Disconnect the power steering pipe from the engine nozzle. Power steering pump, unscrew with the bracket and hang on a wire to the body. Do not twist the hoses and make sure the pump is hung on the hose;

- In the VR6 engine installed secondary air supply, the basic details of which are located close to the radiator. To remove the engine casing must be removed from the fan and secondary air pump motor (see. Sect. 5.2.2); - Disconnect all hoses from the engine coolant hoses and vacuum hoses of ventilation of the engine; - Disconnect from the engine and gearbox all electric wires. Among these wires: alternator, starter, gidronapornogo oil switch, various sensors. Most of the compounds is carried out by means of plug-in pads; - Remove the generator; if installed Manual Transmission: - Disconnect from the clutch slave cylinder hose; - Remove the draft of a gear with a transmission (see. Section 10.1); - Remove both drive shafts from the gearbox mountings (see. Section 11.1); a car with an automatic transmission: - Remove the thrust lever mode selection; - Remove both drive shafts from the gearbox mountings, - If the car is equipped with air conditioning, in addition to this section, be sure to read the relevant recommendations;

|
- Support the engine underneath. In SRT it uses a special device (fig. 21), which is then substituted by a car jack. Besides hedge should lift that supports the top of the loop engine. If the vehicle jack slip, the motor in this case will hold a lift; - Remove the balancer (pendulum) suspension. It is connected with the front support, so you should read the relevant section in order to learn more about its mounting;
| Fig. 22. The right engine mount 1 - bolts
|
- Turn out bolts 1 (fig. 22) securing the support of the right engine mount. Please note that for tightening nuts and bolts of an engine mount, various torques;

- Remove the mounting bolts left engine mount. Fixing support suspension left (Fig. 23) depends on the type of engine installed gearbox. At this stage of work is necessary to unscrew bolts 1 only, the location of which is the same for all types of transmission; - Together with an assistant slowly lower the powerplant from the engine compartment. Make sure the engine is not damaged while the bodywork. Installation of the power unit is carried out in reverse order of removal, and the do the following: - Check the thickness of the lining on the clutch disc. In the case of wear, replace the clutch disc; - Carefully rewound the power unit in the engine compartment. Take care not to damage the parts and components of the vehicle; - The alignment of the engine with fasteners supports suspension, tighten by hand for 5-6 turns of mounting bolts. Shake the engine back and forth (he must not be energized); - Tighten the bolts supports suspension of the power unit the following points: - Pos. 1 = 55 Nm; Pos. 2 = 110 Nm; Pos. 3 = 100 Nm; Pos. 4 = 20 N ?� m (see. Fig. 23) - for the engine with manual transmission;
| Fig. 24. The right engine mount exploded. Tightening torques of fastening of support arm: 1 = 55 Nm; 2 = 60 Nm
|
- Pos. 1 = 55 Nm; Pos. 2 = 60 Nm (fig. 24) - the right-hand engine mounting;

|
- Pos. 1 = 55 Nm; Pos. 2 = 110 Nm; Pos. 3 = 60 Nm (fig. 25) - the right-hand engine mounting on a vehicle with automatic transmission; - Set equalizer (pendulum) suspension (see. Section 13); - Set the drive shafts. Special key to tighten the multifaceted bolts specified torque. For manual and automatic gearboxes different torques (see. "Table of tightening torques"); - Depending on the type of transmission rod set and adjust the gearshift control; - Attach the hose to the clutch slave cylinder and secure with spring clip (for manual transmission); - Attach to the exhaust manifold exhaust pipe with catalytic converter. After aligning the muffler and exhaust pipe hang them on the ring suspension. Watch for correct installation. Rings suspension must have a uniform tension and should not be twisted; - Set the power steering pump; - Replace the cover with the fan and the motor secondary air pump; - Install V-belt drive system of the engine; - Set the throttle cable and check her work; - Set the air intake hose and the air filter; - Install all previously disconnected electrical wires; - Pour coolant in the cooling system when the heater tap is open. Bring the coolant level in the expansion tank to the required level, screw the expansion tank cap. Turn on the engine for a few minutes to, release all air pockets. Then, check the coolant level in the expansion tank and if necessary add coolant; - Bleed the clutch by pumping with the obligatory participation assistant; - Connect the battery and take a test drive. Check all hose connections for leaks; - Enter the code anti-theft system (if installed on the vehicle). At the first opportunity should call the service station to check the memory self-test fault recorder system.
