Transit de-aircon effects

[Andrewbg86]

Basically my question is this. Does totally removing air con save fuel?
So I've got a 2.0 diesel with air conditioning. I very never use the air con so it's not really worth having.
On my engine, the auxiliary belt goes round the alternator, a/c pump, crank pulley, tensioner pulley and two idler pulleys. On the model with no a/c it has a stretchy belt which just goes round the crank pulley and alterntor.
As my aux belt and needs changing, and the tensioner is on its way out, I was considering removing the AC, tensioner and idler pulleys and just fitting the belt for a non AC model, which will save about £60 in parts (not having to buy new tensioners and idlers), and I may be able to make a few quid selling the AC components as well.
But will the tiny bit of weight saved, and the aux belt going round two pulleys insead of 6 save any fuel?

Negligible, it will be 0.05% tops.

most a/c pumps has an electric clutch - if the a/c is off, the pulley just idles around the outside.
If you turn the a/c on and watch the pulley you should be able to see it clicking on and off.

You would probably save more fuel by removing the spare wheel and any other weight you don't need.

However, if you can save money by using the smaller belt and it will have no other effect, I see no reason not to.
