I saved that. Are you able to source the fittings I'll need or do you need me to send them?
A little solenoid on the throttle linkage on my 84 Oldsmobile.When vehicles were carbureted, what adjusted idle speed for the A/C compressor surge?
Was there a device on the carb that would slightly open the throttle?
Also, I am assuming that without a engine computer managing anything, the A/C system at that point would rely solely on pressure sensors to engage its clutch to compress?
I'm guessing from inside the vehicle, when turning on the A/C, you'd be (A) sending power to your low speed fan relay to turn on the engine cooling fans/ or engaging the clutch fan, (B) be turning on some sort of idle controlling solenoid on the carb and (C) sending power to the A/C clutch circuit (with a pressure sensor inline?)...
Exactly. People remember driving $300 rust buckets back when they were young and poor and state it like fact that that is the way they all were.My ‘77 Oldsmobile was an icebox in any weather. 100 degrees, humid, idling in NYC traffic, it would still freeze you. The engine never overheated.
When cars like that (a luxury car, not a cheapie) were new, and when they were maintained, they worked great.
Most people’s experience with cars that had carburetors and AC are with 20+ year old heaps. Worn out fan clutches, poorly maintained cooling systems, undercharged AC, etc. That’s what I’m seeing here.
Not a fair assessment. That’s not how they were when new.
Thats good to know. I am thinking about different plans for a car. Car may very well be carb and def. want A/C for those hot days.Exactly. People remember driving $300 rust buckets back when they were young and poor and state it like fact that that is the way they all were.
I would need them sent. I would mark them, cut the rubber off. If the barbs under are ok I can crimps a new hose on. If not I'll weld on new barbs. Then send them backI saved that. Are you able to source the fittings I'll need or do you need me to send them?
I recall a rental, full size car without many miles on the odometer we were driving out of NYC one time. 90 something, stop and go traffic. Had to kill the A/C when the temp idiot light came on.My ‘77 Oldsmobile was an icebox in any weather. 100 degrees, humid, idling in NYC traffic, it would still freeze you.

Idle was too low or a bad fan clutch. Those fail more than most people realizeI recall a rental, full size car without many miles on the odometer we were driving out of NYC one time. 90 something, stop and go traffic. Had to kill the A/C when the temp idiot light came on.
I've had a bad fan clutch on almost every old car I've owned over the years. Sometimes they don't engage enough others completely engage and sound like a jet engine taking off. I much prefer electric fans now even on an old car.Idle was too low or a bad fan clutch. Those fail more than most people realize
Going back to my original post about the very common failures of A/C systems on cars back in the day: they were not made well at all. Be it compressor, fan clutch, idle speed, gremlins or whatever, they very often failed when it got very hot.I've had a bad fan clutch on almost every old car I've owned over the years.

In my experience clutch fans failed at higher mileage. I had one compressor fail at high mileage. My condenser and current compressor are original 1987 parts.Going back to my original post about the very common failures of A/C systems on cars back in the day: they were not made well at all.

Oh and your one broken rental car doesn't represent all the other cars that had working AC back then.Going back to my original post about the very common failures of A/C systems on cars back in the day: they were not made well at all.

I didn't ride in many cars with A/C back in the day, but the majority did not work well. We are all glad that you never had any problems with those antique systems back then.Oh and your one broken rental car doesn't represent all the other cars that had working AC back then.
