Before reassembly begins, ensure that all new parts have been obtained, and that all necessary tools are available. Read through the entire procedure to familiarise yourself with the work involved, and to ensure that all items necessary for reassembly of the engine are at hand. In addition to all normal tools and materials, thread-locking compound will be needed. A suitable tube of sealant will also be required for the joint faces that are fitted without gaskets. It is recommended that Fiat's own products are used, which are specially formulated for this purpose.
In order to save time and avoid problems, engine reassembly can be earned out in the following order:
a) Crankshaft.
b) Piston/connecting rod assemblies.
c) Oil pump of Fiat Punto.
d) Sump.
e) Flywheel/driveplate.
f) Cylinder head.
g) Coolant pump.
h) Timing belt tensioner and sprockets, and timing belt.
i) Engine external components of Fiat Punto. At this stage, all engine components should be absolutely clean and dry, with all faults repaired. The components should be laid out on a completely clean work surface.
