I’m hoping that someone here might be able to help with this issue:

I’m looking for the actual size of the MkIII unit, or the size of the space behind the dashboard that the heater / AC unit occupies.
Has anyone had experience with replacing the AC unit in their XJS?

The summary is that my Delanair has developed a host of problems and I’m researching a completely new aftermarket install, but need the dimensions to proceed. Ideally before removing the entire interior of the car.

Thanks in advance!

 

l would suggest a measurement of the area in which the unit is installed might be an easier approach. It's not going to be an easy conversion l expect.
l would ordinarily go measure one of my shells for you but away for another few days.

 

I have a spare Mk III in my garage. I will get the dimensions.

It is 16 " across, 16' tall, 12' front to rear, and 45" across the top mounting bar.

This is with the blower motors detached

 

Fantastic, thank you so much for this!!
You’ve saved me a LOT of trouble.

 

Somewhere in this thread there is an example of fitting an aftermarket system to an XJ-S.

Edit: Looks like it starts on page 10.

 

I have a feeling that Old Air make something that might fit the 16" width.

Yes indeed. Taking the Delenaire III out is a MJOR undertaking.

 

This has been exceedingly helpful, I really appreciate the link!! (Also Thorsen for the work & documentation!)

 

Thank you Greg, I’m seeing several that might fit! Have you had any experience with Old Air products?

 

I have not, I am afraid; but they have been widely used in the aftermarket. When my Delanair packs up I thought theirs might fit in the space available. If you find one that does, please let us know.

 

Today I ordered a Hurricane 1100 kit from Old Air, the complete system from condenser to compressor to the in dash system.
I’ll follow Thorsen’s example and document everything for a full writeup in a new thread.

 

Good for you! That will be a very useful and important resource. Do please document particularly how you fit the unit into the body framework under the dash, which I see as the most difficult aspect of fitting any aftermarket aircon system to the XJS.
