It is preferable to dismantle and work on the engine with it mounted on a portable engine stand. These stands can generally be hired from a tool hire shop. Before the engine of Fiat Punto is mounted on a stand, the flywheel/driveplate should be removed, so that the stand bolts can be tightened into the end of the cylinder block.
If a stand is not available, it is possible to dismantle the engine with it blocked up on a sturdy workbench, or on the floor. Be extra careful not to tip or drop the engine when working without 3 stand.
If a reconditioned engine of Fiat Punto is to be obtained, or if the original engine is to be overhauled, the external components in the following list must be removed first. These components can then be transferred to the reconditioned engine, or refitted to the existing engine after overhaul.
