My advice still the same; Grand Marquis

Maybe apples and oranges, but drove my 2012 mustang today and realized it has one of the best AC systems of all of my cars; at least it feels that way. Small cabin area helps I guess. Anyhow I had to check it's AC temps. Thermometer on the back porch was showing 86F. Max AC and fan at mid...

Reply from Vintage Air Bill, 44°F is great, this will provide a very comfortable cabin when in the heat of the summer. Let me provide one small trick to squeeze a few more degrees Directly below the blower motor you will see a small copper tube that goes into the evap. case. Grab the...

Thermometer on my back porch was showing 92F about 3 hours ago.

I agree, but I used my Grand Marquis as a reference and at MAX AC High FAN it too blows around 44F.

Not really. There is a calibration routine that you activate with a jumper to ground off the Heater Box ECU. You can tell the doors and actuators are moving through the ranges as you slide the controls. That's about it when it comes to blend door operation.

I agree and the Vintage Air instructions say the same. The guy who is doing this for me is a retired Ford Master Mechanic and he also says that overcharging is a big NO NO. Having said that I have two other friends who have installed Vintage Air in several Tri 5 Chevys and they claim there is a...

Okay for whatever reason my mechanic friend is gun shy about possibly overcharging the system. From advice I received from a few other AC guys I asked him to add a few more ounces. So we put around 6 ounces more in which is about half a can of R134. We had the fan blowing high speed on the grill...

I remember @threewood did this conversion.

Below is the reply from Vintage Air. Not an expert or even an amateur on charging AC. We didn't have a fan blowing into the condenser. I do know he raised the idle slight while charging. Not sure what to do next. Most shops around me just don't want to look at it. The one shop that is willing to...

I consider you an expert and I would appreciate any advice from you.

Check for pings. The technique I was taught was find max vacuum and then dial back slightly. Distributor curve also needs to be considered. Dead dodge garage on YouTube has excellent videos on timing advance and distributor curves, although the tweaking he does is sort of beyond my ability.

Okay guys (and @Kern Dog vintage air expert) here is where I'm at on this project. Friend's brother who retired after 31 years as a Ford master mechanic came over to vacuum and charge. We watched the gauge at 28 inches of vacuum for a little over a half hour and he called it good. Using a scale...

I've never had any luck with the hammer technique. I've witnessed guys do it and it works, but not for me. I just can't figure out the technique I guess. I've actually used a pitman arm removal tool to separate the steering knuckle from the upper ball joint.

So what was the final verdict here? Did you use the CH-181? I'm looking to go Pertronix in my Coronet which currently has Mopar Electronic ignition.

Was going through all of vintage air boxes in the garage to make certain I didn't miss anything and got a panic attack when I came across a refrigerant line in the bottom of the evaporator packing material. Looks like someone with a Tri 5 Chevy maybe missing a refrigerant line.

Found this in a drawer in the garage today. Picture taken spring 1979.
