It is extremely important to mark the place where the work will be carried out. Undoubtedly, the best place is a workshop. It is very important to have an equipped work area, as well as a place to store the car. If there is no workshop or garage, then at least a flat and clean concrete or asphalt area will be required.
Washing the engine compartment and power unit before dismantling will keep the tool clean and in constant working order.
You will also need a floor lift or hoist. Make sure these devices have the capacity to lift the engine and transmission. Safety is of the utmost importance here, as lifting the engine from the vehicle is a potentially dangerous operation.
If the engine dismantling work is carried out by an inexperienced person, then an assistant is needed. Consult and ask for help from people who have experience in such work. There are many examples of how attempts to dismantle the engine by lifting it from the engine compartment alone ended in failure.
Plan your actions in advance. Before you begin work, rent or purchase all the necessary tools and equipment. Some devices that ensure safety during engine dismantling and installation, as well as reducing labor costs include: (besides the lift) a trolley jack of sufficient lifting capacity, a full set of wrenches and mandrels, wooden blocks, rags and solvent for cleaning up the inevitable puddles from spilled engine fluids. If you are renting a lift, agree on this in advance, having completed all the work that does not require this mechanism. This will save money and time.
Keep in mind that you will not be able to use your car for a significant period of time. To perform some work that is not possible at home due to the lack of special equipment, you will have to contact a car service workshop. These companies work on a schedule and it would be advisable to consult there before dismantling the engine in order to accurately estimate the time costs for repair and restoration of parts.
Always be very careful when dismantling and assembling the power unit. Unconsidered actions can cause serious injuries. Think about your actions in advance. Do not spare time for this, because the main thing is to work without injuries.
