@@RDjax78 Hey man! The Patreon page was mainly created as a simple way for people to donate to the ongoing 944 restoration, as a number of subscribers proactively expressed interest in doing so. There are about 25 posts/articles there that provide some behind-the-scenes insight on the restoration process over the years, but it’s mainly pictures and write-ups, no additional video content. All the payment tiers have access to the same posts and about 20% of the content is duplicated somewhere on the KZread channel. So the channel here is really the main technical resource with the Patreon just acting as a donation conduit, but I didn’t want it to be void of information. The higher tiers include a decal and coffee mug after so many months activity, but that’s the only difference. That said, I’m happy to provide you some additional advice or answer questions about the AC job, feel free to email me, my gmail address is listed in the “About” section of the channel. Thanks!

Great instructions but if I may add a few tips on 134a conversions on the 944. A new parallel flow condenser (I saw you installed a new tube and fin style) will help massively as most oe condensers have 30+ years of crud in them. The second thing is that the mineral oil should be flushed with an ac flush tool and solvent. Other than those 2 additional items your work here is a great benefit to the community.

Great points, thanks for sharing your insights! In a perfect world of optimally performing AC systems, I totally agree. 😂 AC system repair is a fairly specific topic that can get deep pretty quickly, so I elected to demonstrate what I could in a reasonable amount of time. I also figured the average DIY owner wouldn’t take the steps to replace the condenser (given the cost) or remove the expansion valve for a flush of the evaporator (given its inaccessible location), so I stuck to the basics that most people will follow. Not shown here, but performed during the front end rebuild of the car was a removal and liquid flush of the barrier hoses. They were surprisingly clean and dry, my guess is the system was empty and exposed for more than a decade, pretty wild. Out of curiosity, do you have a good lead on an aftermarket partial flow condenser that doesn’t require modification to fit? The only thing I was seeing at the time were the OEM units. Cheers man!

Brilliant video, out of curiosity is it possible to install the whole air conditioning system into a car that didn’t have it installed originally? My 1982 n/a didn’t have it installed and was hoping maybe in future to gather all the parts in putting the system in

@NC944er

Жыл бұрын

Thanks! Yes, it would be a bit of work, but is possible. First step would be to assess what pieces your car has installed and determine what you would need to track down. Does it have an expansion valve installed on the evaporator assembly? If not, the assembly can be removed without removing the dash, just some cramped conditions. Does you car have the correct alternator/compressor bracket to mount an A/C compressor? If not, you’d need to install the correct bracket. Routing for the lines is tightly placed behind the engine, which may require pulling all the wiring harness back to make space, etc.

Another great video. Question: where did you source your AC condenser? I need to do this as well, but I am dragging my feet at the high cost of the OEM condenser unit. Thanks!

I am currently doing this conversion and had a leak at those damn firewall o-rings while doing a pressure/soapy water test. It is possible to replace them... The magic tool is using a flex head ratcheting wrench with those box end socket adapters, so it converts your wrench to a super low profile socket while having any angle you need. Putting the new o-rings on is even more of a pain in the ass - I had a helper hold an extendo flexible grabber that was holding onto tweezers that had an elastic band around it to hold the o-ring; I had them hover the o-ring in place while I did the reach around the cam tower to push it on the hose. Also visibility is awful and most of it is done by feel. Took me a couple hours - never want to do it again

Hey, its sounds like you have a 944 that was factory delivered without AC? If so, it will require quite a lot of work to add the entire AC system, specifically the modifications to the HVAC unit to add the expansion valve, etc. That said, most of the AC components are the same across the base NA cars and the Turbo cars, but the refrigerant hard line from the evaporator to the compressor is a slightly different part on the Turbo. The hard lines would be challenging to install as they route behind the engine, but it can be done, you'd just have to shift a bunch of things around to make space, like the wiring harness that runs along the back of the firewall.
