2. If it is not possible to use a stand, disassemble the engine by placing it on a sturdy workbench or by placing it securely on a hard garage floor. When working without a stand, make sure that the engine does not accidentally tip over.
3. If you plan to replace the engine with a remanufactured one, remove all attachments and external components from the old one and transfer them to the replacement unit. The components to be replaced include:
- a) Generator with brackets;
- b) Components of emission control systems;
- c) Distributor/coil assembly and spark plugs with high voltage wires;
- d) Thermostat with casing cover;
- e) Water pump;
- f) Components of the injection system (EFI);
- g) Intake manifold and exhaust manifold(s);
- h) Oil filter;
- i) Powertrain suspension supports;
- j) Clutch assembly (manual transmission);
- k) Flywheel/drive disk;
- l) Engine back plate.
Note: When removing external components from an old engine, try to remember the characteristic features of their installation. Record in a notebook the mounting positions of gaskets, seals, spacers and bushings, pins, brackets, washers, bolts and other small parts.
4. When selecting a scheme using a reduced block kit consisting of a cylinder block with a crankshaft and connecting rod and piston groups installed in it, also remove the cylinder head(s), oil pan and oil pump from the old unit (see Section Alternative options for engine repair schemes).
5. When performing a complete overhaul of the old unit, disassemble it and remove all internal components. The optimal order of removing components when performing the engine disassembly procedure is given below:
