Attention! Detachment «–» conduct terminals from AB only with the ignition off. At the same time, the fault codes of the KSUD, the codes of the anti-theft system and the individual setting of the audio equipment are erased from the memory device.
Note. Disconnecting the wire «masses» when the ignition is on, it leads to failure of electronic devices.
Depending on the period of manufacture of the car and its model, the layout of its equipment, electrical harnesses, pipes and hoses can be routed in the engine compartment with individual features.
Note. Before undocking and removing the elements, mark them with tags or adhesive tape. Fix on the plan of the engine compartment the location of the units and parts to be removed.
Prepare your workspace before starting work (stand, workbench or shelving), fixtures «11.0.020», «13.5.281», «13.5.282», garage jack, supports (coasters) and lifting device type crane (hoist). Prepare a protective cover or dense fabric material to cover the surface of the wings of the body during work. The engine should be removed from the car upwards, with the gearbox disconnected and the hood fixed. Removing the engine must be carried out in the following order.
Place the vehicle on a ramp or level ground using stands. Apply the parking brake. Record the readings from the SR for diagnosing KSUD.
Note.
- Both exhaust manifolds remain on the engine.
- Do not disconnect the oil lines from the automatic transmission to the heat exchanger. There is a risk of damage to the oil line on the steering gear.
- When installing, observe the tightening torques of the connections.
All work should be carried out with an assistant. Switch off the ignition and disconnect «–» terminal AB. Remove the front crankcase protection panel and stiffening plate.
Take measures to prevent the engine from tipping forward. Remove the exhaust system, automatic transmission / manual transmission, front drive shaft. Attach the rear drive shaft to the body.
Drain and dispose of coolant. Unscrew the mounting of the air conditioning compressor, move it to the side and secure it to the body with a wire clip, do not disconnect the hoses.
Remove the alternator drive belt and air filter housing together with the air flow meter (IRS). Unbolt the automatic transmission heat exchanger from the engine cooling system radiator. Remove the engine cooling radiator and disconnect the oil lines. Remove the washer fluid reservoir and heater baffle.
Fix starter (1, fig. 5.29) with a bolt (2) gearbox to prevent it from falling out.
Unscrew the threaded connection of the power steering oil supply line, place it forward in the engine compartment and take measures to prevent the oil line from falling. Remove the power steering pump. To prevent the pump from falling, secure it to the anti-roll bar with a brace or wire shackle.
Remove the fuel supply line from the distribution line and plug the hoses using tools «13.5.281» And «13.5.282». Collect leaked fuel. Loosen the clamp and remove the fluid outlet hose from the heater.
Loosen clamp (1, fig. 5.30), disconnect the vacuum line (2) from the vacuum pump. Remove from holder (3) vacuum pipeline.
Release the vacuum line (1, fig. 5.31) from the holder (2) and take him aside. Unlock and remove the valve (3) fuel tank ventilation.
Disconnect the engine wiring harness from the electronics box, disconnect «+» wire from outlet «+» AB. Disconnect the wiring harness branch from the gearbox and remove the oxygen sensors in the exhaust gas, fix them on the engine.
Remove baffle (3, fig. 5.32), for which it is necessary to release the hoses and wires from the clamps, disconnect the loop (1), separate the tourniquet (2) wires, unscrew the nut and unscrew the bolts.
Install fixture «11.0.020» for engine and hoist (pic. 5.33). Unscrew the top nuts of the engine mounts on the left and right front side members of the body. Remove the motor connection jumper from «weight» body.
Verify that all hoses, lines and wiring harnesses connecting the engine to its compartment are disconnected, paying particular attention to:
- fuel lines near the cylinder head;
- air conditioning compressor;
- air conditioning compressor pipelines;
- air conditioner condenser;
- an exhaust manifold;
- front axle gearbox;
- steering shaft.
Gently raise the engine with a hoist (crane) and remove it from the compartment, being careful not to damage adjacent structures if they are accidentally touched. For further work with the engine, it must be moved and installed on a special workbench.
The installation of the engine on the vehicle should be carried out in the reverse order, while it is necessary to check the engine mounts, coolant, oil and fuel hoses for the absence of porosity, the absence of delaminations and cracks. Check the presence of centering bushings for connecting the engine to the gearbox. If defects are found, replace the parts with new ones.
Attention! There is a risk of damage to automatic transmission lines and hydraulic oil lines.
When installing the stiffening plate, be sure to track the presence of spacer washers. The process of tightening the new bolts of its fastening consists of two methods - tighten with a torque of 56 N·m (5.6 kgf·m) + Tighten by 90°.
