It is extremely important to choose a suitable place to work. You will need an appropriate workplace and a place to store the car. If a workshop or garage is not available, then in a pinch, a flat, clean asphalt or concrete site will do.
Cleaning the engine compartment and engine before starting removal will help keep the tools clean and tidy.
You will also need a winch for the engine or an A-frame. Make sure the equipment can support the weight of the engine with attachments. Safety is paramount given the potential hazard when removing an engine from a vehicle.
Plan your work ahead of time. Before starting work, prepare or purchase all the necessary tools and equipment. Among the equipment necessary for the safe and relatively uncomplicated removal and installation of the engine (in addition to the winch), include a heavy duty roller jack, a complete set of open end wrenches and sockets as listed at the start of this manual, blocks of wood, and sufficient rags and detergent to clean up spilled oil, coolant, and fuel. If an engine winch needs to be hired, make sure you are prepared and have done all the work that can be done without it. This will save time and money.
Get ready that the car will be idle for a while. Some work that cannot be done independently without special equipment will need to be entrusted to a mechanical workshop. These businesses are often busy with work, so it is wise to consult with them prior to engine removal to determine exactly how long it will take to rebuild or repair components that will require it.
Always be extremely careful when removing and installing the engine. Careless actions can lead to injury. Plan ahead, take your time, and this work, although large, can be successfully completed.
The air conditioning system is under high pressure. Do not loosen any connections or remove any components until the system has been discharged by a qualified person. Always use safety goggles when disconnecting air conditioning connectors.
When removing the M40 engine, it is important not to hold it upside down for more than 10 minutes, as oil may leak from the hydraulic pushers. This will make the hydraulic pushers inoperable and the engine may fail during start-up.
