Removal and engine OHC installation



The engine is taken out from the car without a transmission. The mechanism of corresponding load-carrying capacity is for this purpose used. It is recommended to take advantage for this purpose of the help of the assistant. If you do not possess sufficient experience for carrying out of considered operation, it is recommended to carry out it with participation of the skilled mechanic. Before engine removal it is necessary: to prepare the corresponding tool, capacity for plum of impellent oil and a cooling liquid, cables, the load-lifting mechanism and a hook. For carrying out of considered work the platform where the car can be left with the removed engine should be chosen. Besides, it is necessary will familiarise with the maintenance of the present section.

1. Disconnect a cable of weight from the storage battery and remove the storage battery to exclude short circuit occurrence at performance of works. Removal of the storage battery will allow to release also working space for performance of the further works.
2. Remove a cowl. Preliminary establish a cowl in vertical position and disconnect a hose of giving of a liquid to nozzles стеклоомывателя. Lead round a pencil hinges on a surface of a steel sheet of a cowl later to establish a cowl in former position. Turn away screws of fastening of hinges. Thus the assistant should keep a cowl. Remove a cowl and put it on well protected place. Enclose under cowl edges a thick rag.
3. If the engine understands, it is necessary to merge impellent oil.
4. Merge a liquid from cooling system (Section Refuelling of a cooler of system of cooling of the Head Current leaving and service) and stop up hoses заглушками. Completely remove a radiator as it is described in cooling and heating Systems.
5. Remove a hose всасывания air.
6. Remove приводной a belt of the pump of the hydraulic booster of a steering, remove from the engine the pump or take him aside.
7. Disconnect from the engine all cables, hoses and pipelines. Mark their position.
8. Disconnect from the inlet pipeline a cable of management of gas. Its fastening is shown on an illustration "Connection of a drive of management by gas with the lever throttle заслонки and a support".
9. Turn away bolts of connection of a final collector and a reception pipe of system of release of the fulfilled gases and take a pipe aside.
10. Turn away bolts of fastening of a transmission to the block of cylinders. For this purpose at first turn away the bottom six bolts. Disconnect the working hydrocylinder of a drive of coupling and hang up it on a hose. After that turn away four bolts from the top party of a transmission.
11. A kind on the right and left support of the engine. Turn away bolts of support of the engine from the left and right party and completely remove the left support of the engine.
12. Disconnect a vacuum hose of the amplifier of a brake from the inlet pipeline. For this purpose ослабьте collars also remove hoses in their junctions with a fuel distributive highway. It is necessary to mean that fuel is under some pressure, and hoses should be disconnected cautiously. After a detachment of fuel hoses close their ends заглушками in the form of a bolt of the corresponding diameter for prevention вытекания fuel.


At opening of the pipeline being under pressure, there is a fuel emission. At all have no close a control lamp. At отворачивании connections it is recommended to put on it a wrench and to cover it from above with a rag. After that slowly turn away a hollow bolt.

13. Disconnect and расстыкуйте all cables of system of injection of fuel.
14. Disconnect hoses of heating from an underside of the block of cylinders.
15. Расстыкуйте following electric connections: the distributor of ignition or the ignition module (pay attention for a way of joining with an ignition cable), the gauge of the index of pressure of oil, the gauge of the index of temperature of oil, the gauge of position ВМТ of the piston, the index of level of oil, (if it is established), the gauge of the index of temperature of a cooling liquid, the gauge of the remote thermometer. Not all listed devices are available on each engine. It is important to find and disunite all cable connections, and also accurately to take them aside, having provided possibility unobstructed вынимания the engine from a compartment.
16. Disconnect the bottom protective sheet if it is available.
17. Hook on cables or chains of the load-lifting mechanism for eyes on the top party of a head of cylinders and lift the engine, having torn off it from a suspension bracket so that from has been hung out.
18. Now lift the engine upwards. Watch to damaging any cable connection or the pipeline, and also behind to striking the engine about any elements in an impellent compartment. At performance of described operation it is recommended to take advantage of the help of the assistant.


Engine installation is made in sequence, to return its removal. Thus it is necessary to observe the following instructions concerning first of all of the moments of an inhaling of carving connections.

1. Reliably fix the engine on chains or cables of the elevating mechanism, and cautiously lower it in an impellent compartment. Watch to damaging any elements in an impellent compartment. After engine installation into place tighten bolts of fastening of the engine to a transmission the moment of 76 Nanometers. The left engine mount fix to a longitudinal beam the moment of an inhaling of 52 Nanometers, and both support of the engine will fix to beams of a suspension bracket the moment of 85 Nanometers. After that it is possible to disconnect the engine from the load-lifting mechanism.
2. Establish into place system of release of the fulfilled gases. If necessary replace linings. Bolts of fastening of elements of system grease with greasing. The moment of an inhaling of carving connections of 25 Nanometers.
3. Establish new sealing rings топливопроводов.
4. A vacuum hose of the amplifier of a brake fix the moment of 20 Nanometers.
- At installation of the hydraulic booster of a steering a bolt from outside a pulley tighten the moment of 18 Nanometers, other bolts the moment of 25 Nanometers.
5. Put on клиновой a belt (the arrow on a belt should specify a former direction). Pull a belt as it will be described more low.
6. Fill system of cooling with a liquid (look the Head Current leaving and service). Be convinced that the drain crane on a radiator is closed.
7. After cowl installation check up, whether freely it opens and closed and whether is correct it is established.
8. Join electric connections, watching closely correctness of interface. The error in joining can lead to short circuit.
