I'm fitting a new auxiliary belt to my 3.2, the one I've removed is 2025mm long and the replacement is 1900mm long. Will the new belt fit to my car as if it doesn't I don't want to damage it.
Thanks.

Think you've been given the wrong belt. From memory that sounds like the non-air con version for the 2.5 V6 calibra/cavalier belt. Basically you want a 6PK2020, from any motorfactors.
Mine was from Vx (which failed 6 months later) - now on a Gates, using the above specs. :)
I believe there may be another fractionally different belt length, to account to a slightly large pulley on some models (someone will be along to confirm this) however, by all accounts you don't need to worry too much about this, as the tensioner makes up the slight difference in slack, with no maladies reported. He says, awaiting contradicton... :D
Where did you get it/ask for?

That's 5 inches shorter ... not a chance of it fitting ..... the correct belt can be hard enough to fit sometimes. ;)ï

When you get the right belt my 'top tip' is to get as breaker bar on the pulley. Sounds overkill, but a breaker bar isn't there for 'wusses' it's there for controlled movement. With very little pressure/effort, you can then (after making sure the belt is on the right side of the breaker bar, of course!) ease the pulley over, then slip it on the wheel/pulley. Turns a bit of a two-man job into an easy one man, almost one-handed one.
You can walk to the motorfactors, purchase one, and fit it in your dinner hour and still leave time for a sit down and cuppa, I have! :y

+1 on DBGs breaker bar advice.
Aux belt replacement is really a 5-10 min job when doing like that.
And, 1900mm long belt is for non-air con (I have that one on my car, as I've removed all the aircon bits).

Just to add to DBG's breaker bar(extra long 15mm spanner in my case) tip: route the belt around the grooved pulleys, release the tensioner, and slip the smooth side of the belt onto the water pump pulley.

And while it's off, re-pack idler bearing with grease.

There are two slightly different sized alternator pulleys out there.
Just make sure that there is a bit of spring movement available in the tensioner arm. If it comes up against the stop then something else will have to give - my guess is that the plastic tensioner pulley will be the weakest link..

And a +1 on Nick's time-saver. Perfectly easy if you slip the 'last' bit on the ribbed adjuster pulley, however, once you've done it you realise there's this lovely smooth pulley just sitting there. Like I say, did it in a car park across work in my dinner hour.. :y

OP hasn't been back on since just after asking! :y

Fair dos! :D Well, at least we all know, anyway :y
