Working on the restoration of a Jaguar MK2 at the moment, and I have a =
question for my healey friends.

I am air conditioning this car. My first configuration of pulleys and =
belts can be seen in Image 1. All on one 1/2=E2=80=9D =E2=80=9CV=E2=80=9D =
belt. This approach continues to use the original =E2=80=9Cjockey=E2=80=9D=
 pulley (to the left and above the crank pulley) for tensioning the belt =
although I suppose that it is not really needed since in this approach =
the tension can be adjusted by rotating the alternator.

However, I wonder about having the alternator and the compressor on one =
=E2=80=9CV=E2=80=9D belt as in image 2, and then have the crank pulley, =
water pump pulley, compressor and idler pulley (not tensioned) on a =
second =E2=80=9CV=E2=80=9D belt. I could accomplish this easily as the =
compressor has two =E2=80=9CV=E2=80=9D belt pulleys (one double) and I =
could shift the alternator to the rear to get the proper alignment.

Do I gain much of anything by moving to the two belts?

I have seen several Healeys with the stacked alternator and compressor =
on their own belt. Unlike in the Healey configuration, in my case the =
compressor would be on top and the alternator below.

What are your thoughts? I would appreciate hearing your views about =
this.
