Fiesta Mk5 2001

[fosh100]

Hi,

I have a 2001 1.25 fiesta zetec.

I was looking at changing the cam belt on it.

I know that the aux belt is of the stretch type and so has to be renewed.

I also know that there are special locking tools required to lock up the cams,

WHAT I CANT WORK OUT IS THIS ?

It says to loosen the camshaft Sprockets ??

I dont see a reason for doing this.

I know your are supposed to time the engine to get cylinder 1 to tdc usin the timing pin and then to fit the locking bar to the cams and to remove the crank pulley, but why the cams, the car has no vvt to be set

Can anyone shed a little light on this, anyone who has actually changed a belt perhaps ???????

Thanks nick
