Removal and engine installation

Air central air constantly is under pressure! Before to disunite refrigerator lines or to remove any components of system, make its discharge on a car repair shop of dealer branch or in a specialised workshop.

Removal

 PERFORMANCE ORDER

  1. Dump pressure in the power supply system (the Head of the Power supply system and release of the fulfilled gases), then disconnect a negative wire from the battery.

The given models of cars are equipped by safety pillows. The pillow constantly is in readiness and can work to (be inflated) at any moment at the connected battery. In order to avoid casual operation of system (and receptions as a result of a trauma) each time at work with components of a pillow of safety (including gauges of blow which can be located near to a forward lattice/bumper) disconnect from the battery a negative wire. After battery switching-off before starting to work it is necessary to wait not less than 2 minutes (the system is equipped by the condenser of a delay which should be discharged completely). The Head the System of an onboard electric equipment more in detail see.

  1. Cover wings of the car and forward обтекатель and remove a cowl (the Head the Body). For protection of wings specially formed covers are issued, however also old blankets not is worse will approach.
  2. Remove air cleaner assemblage (the Head of the Power supply system and release of the fulfilled gases).
  3. Empty cooling system (the Head of Adjustment and routine maintenance).
  4. Mark vacuum lines, hoses of systems of decrease in toxicity of the fulfilled gases, electric sockets, tyres of grounding and fuel lines (for the purpose of a guarantee of their correct connection at assemblage) and disconnect them. Just in case make also the scheme of a lining of lines, hoses and wires in an impellent compartment.
  5. Mark and disconnect from the engine hoses of system of cooling.
  6. Remove the fan of system of cooling with a casing and a radiator (the Head of System of cooling, heating and an air conditioning).
  7. Remove приводной a belt () (the Head of Adjustment and routine maintenance).

Gasoline is an inflammable liquid in the higher measure, therefore at work with components of the power supply system of the car it is necessary to observe some special safety measures. Work should be made in well ventilated premise in which should not be working on natural gas and the heating devices equipped with a control torch (such as водогреи and dryers for clothes and footwear) approach to a place of work with the lighted cigarette, open fire or the redurable not protected by a lamp shade Is inadmissible. In view of aggression of gasoline, there where there is a danger of its spillage in the course of performance of any procedure, put on protective латексные gloves. Got on open sites of a body gasoline immediately wash off a plentiful quantity of water with soap. Near at hand always there should be a fire extinguisher of a class of V.Otsoedinite from the engine the fuel lines going the chassis of the car (the Head of the Power supply system and release of the fulfilled gases). Закупорьте the open ends of lines and connecting unions.

  1. Disconnect draught of gas (and also draught of a drive throttle заслонки in a mode kik-daun (TV-draught) and a drive cable темпостата if those are provided) from the engine (the Head of the Power supply system and release of the fulfilled gases).
  2. On the cars equipped with system of hydrostrengthening of a wheel отболтите the pump of the hydraulic booster (the Head the Suspension bracket and a steering). Will put the pump aside, without disconnecting from it lines/hoses and so that the hydraulic liquid did not follow from it (downwards a bottom). Tie up the pump a wire.
  1. Tie up the pump of system of hydrostrengthening of a wheel with the lines connected to it aside - track that the pump has been located downwards by a bottom.
  1. On the models equipped with the conditioner of air отболтите the compressor (the Head of System of cooling, heating and an air conditioning) and also shift it aside. Do not disconnect from the compressor hoses.
  1. Отболтите the compressor of the conditioner of air also will put it aside (without disconnecting hoses).
  1. Merge impellent oil (the Head of Adjustment and routine maintenance) and remove the oil filter.
  2. Remove a starter (the Head System of an electric equipment of the engine).
  3. Remove the generator (the Head System of an electric equipment of the engine).
  4. Отболтите from the engine a reception pipe () systems of release of the fulfilled gases (the Head of the Power supply system and release of the fulfilled gases).
  5. If works are made on the model equipped АТ, give fixture of the converter of rotation to приводному to a disk (the Head Automatic transmission).
  6. Prop up transmission by a jack. Between a head of a jack and картером transmissions for loading distribution lay wooden брусок. Are issued special трансмиссионные the jacks equipped with safety chains - whenever possible take advantage of one of the such.
  7. Connect to engine eyes an elevating rigging (slings or chains).
  8. Deduce on a working point лебедку тельфера and connect a rigging to its hook. Choose a weak point of a sling (chain), however do not lift while the engine.

Do not stand and do not perform any works under the engine, hung out only by means of лебедки or other elevating equipment.


  1. Connect the elevating rigging fixed on the engine to a hook лебедки and choose a weak point.
  1. Give bolts of fastening of transmission to the engine.
  2. Give bolts of fastening of support of the engine to a frame.
  3. Once again make sure that the engine is completely disconnected from transmission and a car frame. Disconnect everything that have forgotten.
  4. Slightly raise the engine. Cautiously advance it forward, disconnecting from transmission. If works are made on the car equipped АТ, take measures that the rotation converter has not dropped out of transmission (fix on aperture walls картера pair of a manual vice). On models with РКПП the primary shaft should leave coupling completely. Then slowly lift the engine and take it from an impellent compartment.
  5. Remove a flywheel/privodnoj a disk and establish the engine on the assembly stand.

Installation

 PERFORMANCE ORDER

  1. Check up a condition of support of the power unit. If rubber pillows are worn out or damaged, replace them.
  2. On models with РКПП establish a coupling basket (the Head the Manual box of a gear change). Now it will be a high time to replace a conducted disk.
  3. Cautiously lower the engine in an impellent compartment - track correctness of combination of components of support.
  4. On cars with АТ make a joint of the converter of rotation and a cranked shaft (the Head Automatic transmission).
  5. At РКПП slightly grease a pin of a primary shaft with high-temperature greasing and enter it into directing bearing of a cranked shaft so that the dome картера has appeared заподлицо with the engine block.
  6. Establish bolts of fastening of the engine to transmission and strongly tighten them.

Do not try to use AT ALL fixing bolts for engine pressing to transmission.

  1. Installation of the remained components make in an order, the return to an order of their removal.
  2. Necessarily fill in a cooler, impellent oil, a liquid of system of hydrostrengthening of a wheel and трансмиссионную a liquid.
  3. Start the engine and check up it on leaks and serviceability of functioning of all units and accessories, then establish a cowl and spend trial runs.
  4. Make a recharge and check on leaks of a central air of air.
