Great cars, those late 80s Accords. Built to exacting standards.This is so right. Those A6 GM units (Frigidaire?) with R12 and POA (Pilot operated absolute) were fantastic. Those large 4 core Harrison radiators (copper?) helped keep it cool.
I still have a 87 Accord with R12 in it and working great. Haven't recharged it for at least 20 years. Don't drive it much but still......
I forgot the model #'s but Ford and Mopar also had great systems also back in the day.
GM did as well during the '84 model year (at least some car lines). The hoses that were "Goodyear Galaxy" were barrier hoses. My early '84 did not have them. The crimps were greatly improved as well.Ford switched over to barrier hoses sometime in the late 80s. Barrier hoses go a long way towards stopping R12 (and R134a) leakage.
Or there was a solenoid valve that applied vacuum to a diaphragm that " lightly bumped up the idle." That's what my Mazda had (or would've, if it had had air conditioning). They used the same device for both that purpose and to open the throttle slightly when coasting above certain engine speed when coasting for emissions reasons.... As engines got smaller and less powerful, there were small electronic solenoids that lightly bumped up the idle. When the A/C clutch came on, so did the carb balance solenoid.

That would not surprise me, as the old fittings (50s-60s GM) with A/C gear clamps are not recommended with R134a either.My 1984 Cavalier has non-barrier hoses. I have read that you cannot or should not use fittings designed for non-barrier hose with barrier hose because the barbs will damage the nylon liner in the barrier hose.

The fittings and crimps were completely different from the original (10/83 build) on the GM (Goodyear Galaxy) hose set for my '84 Caprice.
Those always leaked!

Barrier hoses with the correct crimpsGreat, what can I replace them with?

Won't the barbs designed for regular non-barrier hose damage the inner liner? Which means I need to replace the fittings too.
Makes sense. My mechanical injection diesel had a cpu controled air pump that was in turn "sucking" on a small bladder which was pulling a lever on the injection pump to bump up the idle when cold and AC on, and also a sensor to disengage the AC compressor at WOT (well, pump lever maxed out) in some temperature conditions. Timing was controled by yet another solenoid on the pump.I think some had a WOT switch that would disengage the compressor at full throttle so it wouldn't zap power from the engine. I've never owned or worked on a carbureted car so take that for what it's worth.
Speaking of refrigerant, how much is a pound of R-12 today?...... And it still has to be "available" if cocaine and Fentanyl are.
You cut off the old barbs & weld on new barbs made for barrier hose.
If you're building a system from scratch.....You can usually buy fittings & manifolds made with barrier hose barbs/crimps.
Doesn't seem to. I've been making ac hoses for decades that way. That's how the supplier set me up.Won't the barbs designed for regular non-barrier hose damage the inner liner? Which means I need to replace the fittings too.
Someone can. I can't. The closest place I found that does work like that is all the way in Richmond, VA, a good 90 miles away. On the other hand, if I want to go bribe a congressman, that's only a 20 mile drive.
No AC hoses are listed as replacements for this car anywhere I've looked, as far as I can tell none were ever available, and GM's solution for hose replacement was to cut the crimp off and use hose clamps with a new hose.
