Punto (Mk2/2b) Changing a Fiat Punto 1.2 8v Mk2 Alternator

Start with making sure the handbrake is on - and popping the bonnet
With a 10mm Socket or Spanner Disconnect the battery, you don’t need to remove
just Simply Disconnect the terminals and push away from the battery

Next if you are using a new alternator, it won’t need any prep work, but like me the old wires have to be removed from the scrappy cars alternator
Using a 8mm Socket I simply undid the Nut and pulled the wires off
And the larger Red Wire uses a 13mm nuts, with a socket undid and pulled the wire off

with the car now Discharging, Spray a little WD40 onto the 3 Bolt as mentioned earlier

Using the 17mm socket or spanner Start my Loosening all the Bolts that retain the alternator in place
Don’t Fully remove as you don’t want it to just drop off
Once loose I Removed them by hand holding the alternator to prevent it dropped
The sliding points should now allow you to remove belt tension and just slide it off
Once free - lay the Unit down - I rested it on the Steering Arm, won’t do it any harm

Undo the 2 wires from the back and Retain the nuts

Once Free From Bolts wires and Belts
Remove unit from the car

Collect your replacement unit and fit it into the same position as you did when removing the wires
Make sure you refit the wires in the correct poles and correct way - so not to strain the cables
Once cables are fitted - slide the unit up into place on the bolt holes and sliders

Loose fit the bolts - so that the sliders remain free to rock back and forth

Slip the Belt back over the top of the Pulley

Push the Alternator Away from the Engine towards the Firewall/Scuttle panel off the car
The belt will now become tight, simple Nip the 2 Bolts up nice and tight to prevent it loosening its tension
Once tight, refit the Bolt and Nut as well - making sure its tight

If the belt is tensioned okay, it shouldn’t squeal
Too loose and it'll squeal like a pig

Once your alternator is secure and belt tensioned
Double check all your bolts are tight You really don’t want to loose them on the motorway and for the belt to slip off and stop charging when you need it most

If your happy its secure - Reconnect the battery.
