Cleaning of an impellent compartment and the engine before the beginning of removal will help to preserve tools in purity and an order.

Also the winch for the engine or And-shaped is required..... Be convinced that the equipment will sustain engine weight with hinged components. Safety has paramount value, considering potential danger at engine extraction from the car.

Plan work in advance. Before the beginning of work prepare or get all necessary tools and the equipment. To number of the equipment necessary for safe and rather simple removal and installation of the engine (in addition to the winch), the powerful roller jack, full sets of rozhkovy keys and face heads as it is specified at the beginning of the management, wooden whetstones and rags and detergent enough for removal of the spilled oil, a cooler and fuel belong. If the winch for the engine is necessary for hiring, be convinced that you are ready to it and performed all works which can be made without it. It will save time and money.

These enterprises are often busy, therefore it is expedient to consult with them before engine removal precisely to define time necessary for restoration or repair of components which will demand it.

Always at removal and installation of the engine be extremely careful. Careless actions can lead to traumas. Plan forward, do not feel sorry for time and this work, though big, it can be successfully executed.

Central air of air is under a high pressure. Do not weaken any connections and do not remove any components while the system will not be discharged by the qualified expert. Always at a detachment of connectors of central air of air use goggles.
