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

Getting around the coolant pipe problem:

As you can see the stilo has a 2 way pipe coming from the water pump. The problem with this is that it hits the radiator nicely when left like this.



Soo....
If you still have your cento engine brilliant as you can remove the coolant pipe from this rather than buy one. I would still advise you buy a new sealing ring just in case however. Here is the difference:



To replace this, simply undo the 2 bolts holding it in place and twist out. To remove the rubber seal use a small flat screwdriver, being careful not to scratch the housing surface.
Clean where the seal locates and insert the new seal
Push the cinquecento pipe into place and put the 2 bolts back in to hold it in place.
