A/c diy

[witt]

Hi, the A/C on my 1988 Carrera Cabriolet is working without getting sufficiently cold. Just watched a video refilling the freon with ACPRO products.
Question one: Has anyone done this work and how happy are you with it.
Question two: Where is the "low pressure port" located on my car ?
Any advise would be greatly appreciated.

CHEERS !
WITT !

PS: Where in Canada is that product available ?

On the lower right-side of the picture, the red cap is the high pressure port, the blue cap behind and below the red is the lower pressure port (points towards the front of the car). If your AC has been converted to 134 this is what you should see, and by the way if your ports have not been converted to 134 style you won't be able to connect using the adapters from C Tire.
C Tire carries a similar AC refrigerant under the brand Red Tek, none of the aftermarket refrigerants are recommended by the OEMs or AC professionals. In other words use at your own risk, some have had good luck with them and others won't touch them.

most of these A/C products are propane based. Propane is a much more efficient refrigerant than 134 so you need less.

Licensed shops won't touch it because by state law they have to use and dispose 134 properly. Propane is a natural gas and can be vented to the atmosphere.

Use a vacuum pump and a set of gauges when you install this stuff. I did it on our Chevy trucks and it worked very well.

there were some posts here on this site about these gases so do a search and you will find lots of discussion.

They do work well in older 911 A/C installations. Do some Google searches and you will find lots of sources.
