Default Cambelt change on Fiat Punto

Hi guys

Realised this weekend that the cambelt is due for renewal on my 53 plate
Punto 1.2 8v. It's 5 years or 72k miles. Although I have only done a
little over 30k the 5 years is this month. The garage who performed the MOT
said the 8v is relatively quite easy to change.

Are any specialised tools required in replacing the cambelt? Thinking of
maybe giving it a go myself?

they are a pleasure to do as they are so simple and access is good. The
only problem is that in theory a tensioning tool is needed to set the right
belt tension. I have never used one and I don't actually know anyone that
does. I would set the tension by feel, allowing a new belt to be twisted
nearly a quarter turn on the long run using two fingers to twist with. run
the engine for a while, listen to make sure it is not too tight (will whine)
or loose (flaps about) , turn off and double check and bolt the covers back
on.

The engine is a freewheeling type, so unless you are very unlucky a belt
failure will NOT damage the engine, so you don't need to be in too much of a
hurry to change it.

In broad terms:

take off the wheel, take off the splash guard, remove the alternator belt,
move or remove the coolant tank, undo the crank pulley, remove the cam belt
cover, turn the engine to line up the marks on crank pulley and cam wheel.
slacken tensioner, replace belt, retension, recheck marks, replace crank
pulley, start and run, recheck, reassemble the rest.

If you are not too confident then at least get a manual to read up and see
the the pictures.

It really is the simplest and safest one to do that I can think of.

Just one further question. I have seen references to cambelt and cambelt
kit? Is the only difference that the 'kit' also contains the tensioner? Is
it also best to replace the tensioner whilst you have the belt off?

On a difficult engine or one known to be problematic then change the
tensioner every time, on a low mileage, easy one like yours I would not
bother unless it feels rough or is noisy. The kits generally have a belt,
one or more tensioners plus bolts etc. if needed.

Replacing the water pump is worth considering, but probably not at your
mileage, maybe next time.

Seconded. The only reason the belt is being changed is due to chances
of the rubber perishing with age.

What's a freewheeling engine?
