Removal
- Disconnect the wires from the battery terminals.
- To remove the engine, perform the following operations sequentially.
- Relieve the fuel pressure in the fuel system. See chapter "Reducing pressure in the fuel system", attached in the section "Multi-Point Fuel Injection (MPI)".
- Remove the hood.
- Remove the radiator.
- Remove the gearbox.
- Remove the lower engine splash shield.
- Remove the air filter.
- Remove the exhaust pipe.
- Unscrew the bolts and remove the accelerator cable mounting clamp (Fig. 3.44).
Fig. 3.44. Connection points of connectors and hoses to the engine: 1 - accelerator cable fastening clamp; 2 - vacuum hose; 3 - Boost pressure sensor and bracket; 4 - brake booster vacuum hose; 5 - knock sensor connector; 6 - injector connector; 7 - connector for the temperature sensor of the air entering the engine; 8 - connector of the electromagnetic valve for cleaning the adsorber; 9 - EGR solenoid valve connector; 10 - ignition distributor connector; 11 - coolant temperature sensor connector; 12 - coolant temperature gauge sensor connector; 13 - throttle position sensor connector; 14 - Throttle control servo connector; 15-Wire harness mounting clamp; 16 - wire connecting the engine cylinder block to the "ground"; 17 - heater hose; 18 - High pressure fuel hose; 19 - fuel return hose
- Disconnect the vacuum hose.
- Remove the bolts and the boost reduction sensor and bracket.
- Loosen the clamp and disconnect the brake booster vacuum hose.
- Disconnect the connectors from the knock sensor, injectors, engine intake air temperature sensor, adsorber cleaning solenoid valve, exhaust gas recirculation solenoid valve, ignition distributor, throttle position sensor, throttle control servo, coolant temperature sensor, and coolant temperature indicator sensor.
- Remove the clamp and move the wiring harness away from the engine.
- Remove the bolts and disconnect the wires connecting the engine cylinder block to the ground.
- Loosen the clamps and disconnect the engine cooling and heater hoses.
- Remove the bolts, disconnect the high pressure fuel hose and remove the O-ring seal.
- Loosen the clamp and disconnect the fuel return hose.
- Loosen the tension and remove the power steering pump and air conditioning compressor drive belt (Fig. 3.45).
Fig. 3.45. Removable elements and engine mounting elements: 1 - Power steering pump and air conditioning compressor drive belt; 2 - Power steering pump and bracket; 3 - air conditioning compressor; 4 - wires for connection to the battery terminals; 5 - bolt for fastening the hydraulic hose of the power steering pump, 12-14 N·m; 6 - engine bracket; 7 - engine
- Remove the bolts and remove the power steering pump along with the attached hose and bracket.
Note: Use a cord or soft wire to secure the removed power steering pump to the engine compartment so that it does not interfere with engine removal.
- Disconnect the connector, unscrew the bolts and remove the air conditioning compressor from the bracket along with the connected hoses.
Note: Use a cord or soft wire to secure the removed compressor in the engine compartment so that it does not interfere with engine removal.
- Remove the power steering pump hydraulic drive hose mounting bolt.
- Place a hydraulic jack under the engine.
- Remove the special tool used to remove the gearbox from the engine.
- Secure the engine to the crossbar and hang it on a hoist or similar device (Fig. 3.46).
Fig. 3.46. Using a crossbeam to lift the engine from the engine compartment
- Place a block of wood between the jack base and the engine oil pan and lift the engine slightly to relieve the jack from the weight of the engine, then remove the engine mount bracket.
- Make sure all wires (electrical connectors), hoses, etc. are disconnected from the engine, and then slowly lift the engine up out of the engine compartment.
Installation.
- Installation is carried out in the reverse order of removal, taking into account the following.
- When installing the motor, make sure that no wires, hoses or wire connectors are pinched.
- Place a trolley under the engine; hydraulic jack (inserting a wooden block between the jack support foot and the engine oil pan) and install the engine support bracket, adjusting the position of the engine using the jack.
- Support the engine with a jack and disconnect the hoist.
- When installing the high pressure fuel hose, lubricate the O-ring with a small amount of clean engine oil (fig. 3.36). Do not allow oil to enter the fuel line.
- Slightly turning the flange of the fuel hose to the right and left, carefully insert it into the fuel line so as not to damage the O-ring seal. After installation, check that the hose rotates smoothly in the fuel line.
- If the hose flange jams when turning, damage to the O-ring gasket may occur. Disconnect the flange (complete with hose) from the fuel line and check the gasket for any damage, then insert it back and check that it turns smoothly.
- Install the high pressure fuel hose mounting bolts and tighten them to 5 Nm.
- Connect and adjust the accelerator cable.
