Removal and engine installation

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

 REMOVAL

1. Disconnect a weight cable from the storage battery. The battery is in a luggage carrier behind the right lateral 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 to the Section Removal and cowl installation.
3. Remove RKPP, address to the Section Removal and RKPP and AT installation.
4. Lower the car on wheels.
5. Remove the air filter with a measuring instrument of weight of air, address to the Section Removal and installation of the case of the air filter and a measuring instrument of weight of air.
6. Remove the fan, address to the Section Removal and installation of the fan and the fan coupling.
7. Remove maple a belt, address to the Section Removal, installation and a tension of a maple belt.
8. Merge cooling liquid, address to the Section Replacement of liquid of system of cooling. Check of frost resistance of a cooler. Visual check of system of cooling.
9. Remove a radiator, address to the Section Removal and radiator installation.

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

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

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

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

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

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

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

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

If open гидропроводы, after installation it is necessary to remove air from system, address to the Section Check of level of liquid of system of hydrostrengthening of a wheel.

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

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

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

19. To Zastropta engine. For this purpose a cable or a chain assign load-lifting eyes of the engine. Slightly raise the engine the shop crane. Address to an accompanying illustration.

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

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

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

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


 INSTALLATION

1. Check engine support, hoses of cooling liquid and oil on existence of a time and damages. If it is necessary, replace them.
2. Check ease of a course of radial ball-bearings in cranked to a shaft and the bearing of switching off of coupling, and also the lever of switching off of coupling.
3. Check, whether the thickness of overlays of a conducted disk of coupling, and also a condition of slips is sufficient. At big term of operation of coupling it is expedient to replace it.
4. Carefully enter the engine into an impellent compartment. When lowering watch the engine direction to exclude damages of primary shaft of a check point, couplings and bodies.
5. Screw nuts of fastening of support of the engine, without tightening them.
6. Lift and establish the car on supports.
7. Establish RKPP, address to the Section Removal and 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: Carving М8 moment of 25 Nanometers, carving М10 moment of 45 Nanometers.

10. If the cooling compressor acted in film, fix it.
11. Fix the power steering pump, address to the Section hydropump Fastening.
12. Put on and pull maple a belt, address to the Section Removal, installation and a tension of a maple belt. 13. Join shtekerny connections of the sensor of recognition of the cylinder and the pulse DME sensor of a flywheel. Join shtekerny connections of the sensor of temperature, the remote thermometer, the sensor of the index of pressure of oil and the valve of adjustment of idling, address to the subsection "Removal".
14. Establish the inlet pipeline, address to 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 collars.
16. Establish on a head of cylinders a shtekerny level and fix it.
17. Establish spark plugs.
18. Establish a cover of air intake and fix it screws, address to the Section Removal and installation of a drive of a screen wiper/cover.
19. Fix on the generator electric wires, address to the Section Removal and generator installation.
