Cinquecento/Seicento 1.4 engine into a cinq (useful info and links)

Right first off you need to have your new engine in front of you.
If you have the wiring loom attached go around and undo it all.
There is a sensor on the back of the engine, this can just be left alone as it will no longer be required.
Cut off the old alternator belt and throw away
Unbolt the power steering pump, but beware that there may still be fluid inside and is an irritant, will strip paint, etc
Remove the remaining alternator bolts, one of which goes through the engine mount, then withdraw alternator
Put the powersteering pump and alternator in a box marked (for sale on ebay)
Unbolt the 3 engine mounts (1 is attached to the alternator and 2 on the gearbox if you bought it with the engine. May have been removed already.



The alternator actually covers one of the new mounting holes for the cinquecento engine mount, so don't panic when you cant see the 3 in a triangle.

If you have all the airfilter box, remove this and add it to the ebay box
Unbolt the 4 bolts that hold the throttlebody on and add the throttle body to the 'box'

You now have your decision to make regarding the inlet manifolds. You have 3+ options:

Option 1
Leave the stilo inlet manifold and run with the stilo injectors. If you wih to
do this you will need a fiat punto 1.2 16v MAP sensor. With this sensor in front of you, the problem with it is it is slightly too wide to fit in the stilo inlet. So what you do is take the 2 rubber rings from the sensor. Then carefully sand a little bit of the edge off. I also sanded a tiny bit from where the rings sit, so they sit can push in a little further when mounted.
The mounting hole for this sensor lines up nicely on the stilo inlet

Option 2
Use the punto 1.2 16v inlet manifold with the 1.2 16v injectors and fuel rail.
You then use the 1.2 16v MAP sensor

Option 3
Use the punto 1.2 16v inlet manifold with the fiat brava/o 1.6 fuel rail and fiat stilo injectors. You need this fuel rail to allow the injectors to mount correctly.

Another option
use a bravo inlet manifold and mess around trying to wire up a suitable MAP sensor etc. Not recommended.


Make sure all of the oil is out of the engine and gearbox before going any further. Drain into suitable sealed container and dispose of in an environmentally friendly way.

Remove the 4 coils from the tops of the spark plugs. These can be added to the 'box'



Undo the spark plugs. This stops pressure build up inside the engine while timing. Make sure nothing drops into these holes by putting some tape over the tops.

You can now unbolt the bracket that holds the coil packs to the head. Now using the punto bracket and coil packs bolt them in its place with a thin layer of sealant.

The new thermostat can now be fitted.
