how did you come out? Having a clean radiator and the original fan and a pusher fan in front has worked well for me. now that it's only in the 80'-90's the ac is super cold

The passenger seat is 15 miles an hour faster than the drivers seat.

Gigem, what type of condenser cooling fan are you using? I am working on an AC in my 71 GTV and it doesn't look like I have room in front of the condenser for a fan, under 2.5". Is that the Nostalgic air condenser?

Thanks TD

I used a low profile fan from Classic Auto Air, the company that makes the rear unit kit. I can't remember right off the bat the part # but it fits in the 2 1/2 inch space in front of the radiator.

Trav,

I managed to get a condenser and 10" fan into my '74 105 GTV without too much difficulty. The fan attaches to the front of the condenser as a pusher fan. The fan has a 254 mm diameter (10") and is 57.15 mm thick.

...see the following post for details:

Hi, can anyone offer advice on assembling beadlock connectors? I am having great difficulty getting the hose to bottom out in the fitting. I have tried lubing with AC oil, a little heat and stretching the hose with a cone.

The only instructions I found on-line said to "assemble with a forceful twisting motion".

Thanks!

mine went in easy with a touch of silicone spray. Make sure your clock the positions of the hose in relation to the fitting before you make your crimp. You probably already knew that but didn't want to assume. Is the OD of the hose close to the ID of the fitting barrel? No burs or anything like that for the hose to catch on?

Quantity of R134a

Hello,

I've changed my old big heavy original borletti serpentine condenser for the Nostalgic Air Parts superflow one. perfect mount, I've made 4 parts to fix it on the original hole. It seems to be original one ! I've put a SPAL 10" 830CFM or 1410m3/h ref is VA11-AP7/C-57s (it's a real turbina) in front and let the original fan mounted on the water pump because I've tried to replace it with a SPAL before changing my condenser and the temp was badly higher when the car was running on highway for a long time in summer. For this the original fan with the shroud is better at 3000rpm or higher than a electric one but the electric one was better when I was in the traffic jam. So I've decided to mix both. The front SPAL is coupled with a thermocontact switch 77-82C down the radiator and there is switch inside the car (I've recuperate the lighting tacho switch for this) in case.

I let a binary pressostat with high pressure cut at 28bar

But I wonder how many R134a you've put inside the circuit. The original Alfa Romeo documentation recommend 1kg of R12 freon. We've put 700gr of R134a with the old condenser in brass but now we only put 500gr...

Thanks !

go by what the guages show is your best bet to keep from overpressuring it.
