Removal and installation of the engine

Depending on year of release and the equipment of the car electric wires, vacuum hoses and hoses of the cooling system can have various laying and accessions in a motive compartment. There is no opportunity to describe laying of all connections. Therefore before dismantling it is recommended to mark wires and hoses for a possibility of their correct assembly. Below removal of the 6-cylinder engine is described.
Before removal of the engine it is necessary to remove the manual box of gear shifting (MBGS). The engine without RKPP is taken out upward. The final collector and the generator from the engine will not be washed away, inlet pipeline is removed. Removal of the engine requires the crane.
Besides, for dismantling of connections from below of the car the corresponding supports and the garage elevator are required. Before installation of the engine in a compartment wings have to be protected by the corresponding guards.

 REMOVAL

1. Disconnect a weight cable from the rechargeable battery. The battery is in a luggage carrier behind the right side facing.

At a detachment of the battery the memories given in electronic blocks, for example, memories of malfunctions of the engine are erased.

2. Remove a cowl, address the Section Removal and installation of a cowl.
3. Remove RKPP, address the Section Removal and the RKPP and AT installation.
4. Lower the car on wheels.
5. Remove the air filter with the measuring instrument of mass of air, address the Section Removal and installation of the case of the air filter and measuring instrument of mass of air.
6. Remove the fan, address the Section Removal and installation of the fan and coupling of the fan.
7. Take off maple a belt, address the Section Removal, installation and a tension of a maple belt.
8. Merge cooling liquid, address the Section Cooling System Liquid Replacement. Check of frost resistance of a cooler. Visual check of the cooling system.
9. Remove a radiator, address the Section Removal and installation of a radiator.

If hoses of cooling liquid are fixed by tape collars, cut off their bokorezam and at installation fix screw collars.

10. Remove spark plugs, address appropriate section Check and replacement of spark plugs.

11. Remove hoses of cooling liquid from the crane of a heater and a heater, having opened previously collars. Address an accompanying illustration.

12. Rasstykuyte shtekerny connection, having pressed wire clips. Address an accompanying illustration. 1 - temperature sensor, 2 - the remote thermometer, 3 - the oil pressure relay sensor, 4 - the idling adjustment valve.

13. Rasstykuyte shtekerny connection under the inlet pipeline. An arrangement of plugs, looking in front, following (address an accompanying illustration): the plug 1 - the sensor of a detonation (is closed), 2 - the pulse sensor of a bent shaft, 3 - the sensor of recognition of the cylinder.

14. Disconnect a cable from the generator and a starter, address also the Sections Removal and installation of the generator and Removal and installation of a starter.

15. Disconnect a cable plait at the block of cylinders, having turned off bolts, and take him aside. (address an accompanying illustration)

16. Turn off bolts of fastening and remove the pump of the power steering and take him aside, without disconnecting hoses. Address an accompanying illustration.

If gidroprovoda open, then after installation it is necessary to remove air from system, address the Section Check of Level of Liquid of System of Hydrostrengthening of a Wheel.

17. Turn off 2 bolts of fastening of the tank of the hydraulic booster and fix it aside by a wire. Address an accompanying illustration.

18. Cars with the conditioner: Turn off bolts of fastening of the compressor of cooling and take him aside with the attached hoses.

It is not necessary to open at all a contour of cooling of the conditioner since cooling liquid is poisonous and at hit on skin the burn can cause it. Address an accompanying illustration.

19. Zastropte engine. For this purpose fix a cable or a chain for load-lifting eyes of the engine. Slightly raise the engine the shop crane. Address an accompanying illustration.

20. Turn off nuts of fastening of the left and right support of the engine, and also disconnect from the engine a weight cable (right arrow on an accompanying illustration) at the right support.

21. Check whether all hoses and wires going from the engine to a body are disconnected. After that take out the engine the shop crane.

When raising the engine you watch its direction to exclude damages at a contact with adjacent designs.

22. It is not necessary to hold more than 10 min. removed engine turned since in this case oil follows from compensators of gaps of valves that can lead to an exit them out of operation. If it is necessary to turn the engine, remove compensators.


 INSTALLATION

1. Check engine support, hoses of cooling liquid and oil for existence of a time and damages. If it is necessary, replace them.
2. Check ease of the course of radial ball-bearings in cranked to a shaft and the coupling switching off bearing, and also the coupling switching off lever.
3. Check whether thickness of overlays of the conducted clutch plate, and also a condition of slips is sufficient. At the big term of operation of coupling it is expedient to replace it.
4. Carefully enter the engine into a motive compartment. When lowering you watch the direction of the engine to exclude damages of a main shaft of the check point, coupling and a body.
5. Screw nuts of fastening of support of the engine, without tightening them.
6. Lift and install the car on supports.
7. Establish RKPP, address the Section Removal and the RKPP and AT installation.
8. Lower the car on wheels.
9. Shake the engine for its self-installation. After that tighten nuts of fastening of support the moment of 45 Nanometers. Fix a weight cable on the right beam.

Fastening of support and holders of the engine is carried out by the next moments: M8 carving moment of 25 Nanometers, M10 carving moment of 45 Nanometers.

10. If the cooling compressor was removed, fix it.
11. Fix the power steering pump, address the Section Fastening of a Hydraulic Pump.
12. Put on and pull maple a belt, address the Section Removal, installation and a tension of a maple belt.
13. Join shtekerny connections of the sensor of recognition of the cylinder and pulse DME sensor of a flywheel. Join shtekerny connections of the sensor of temperature, remote thermometer, sensor of the index of pressure of oil and the valve of adjustment of idling, address the subsection "Removal".
14. Install the inlet pipeline, address the Section Removal and installation of the inlet pipeline.
15. Attach to a head of cylinders all electric wires, vacuum hoses and hoses of cooling liquid and fuel hoses according to markings. Fix hoses and electric wires by collars.
16. Establish a shtekerny level on a head of cylinders and fix it.
17. Establish spark plugs.
18. Establish a cover of air intake and fix it by screws, address the Section Removal and installation of the drive of a screen wiper/cover.
19. Fix electric wires on the generator, address the Section Removal and installation of the generator.
20. Fix a generator cover.
21. Check the filtering element of the air filter. If necessary beat out it or replace, address the Section Removal and installation of the case of the air filter and measuring instrument of mass of air.
22. Put on hoses of cooling liquid the crane of a heater and fix them by collars.
23. Establish a radiator, address the Section Removal and installation of a radiator.
24. Install the fan, address the Section Removal and installation of the fan and coupling of the fan.
