Replacing the vacuum lines is a good place to start. I can't find anywhere to buy it other than from some redneck in his back yard on craigslist. I did so with my car. I can't find anywhere to buy it other than from some redneck in his back yard on craigslist. Max cooling is selected with recirculation on.
In fact if you do not follow the recommended procedure your air-conditioning system will probably not blow cold for long. I can buy R-12 all day any day. The vacuum storage tanks started to leak and would not store vacuum. R-12 is not illegal to use or own at all for those with proper certification. If the relative humidity is 70% on a 95° day the temperature output could be as high as 70°. On this auto repair information blog I have written a lot about my that were needed.
This is one problem I experienced with my Z as well. In this year 300zx, the problem was on the vacuum lines, check the whole vacuum system for some air leaks on the hoses. When I got this car it had r12 Freon in the system as you would expect from an older vehicle such as this. Re: Fixing an air-conditioner in a '88 Z31. I didn't even change out the receiver drier on the last one I did although it's probably a good idea cost of fittings, o-rings, ester oil, and r134a. I have also written many air-conditioning articles and you can head back to the main page and see the latest posts. I have done conversions by simply evacuating the R-12, replacing all easily accessed o-ring, draining as much old oil as possible, adding ester conversion oil, and then pulling system into vacuum for 15 minutes.
Every once in a while I get some traffic that is related to this particular automobile. At idle there was plenty to hold the air direction control doors in their proper position but as you step on the gas pedal you start to lose manifold vacuum and that is where the storage tank comes in. There is a heat sink radiating plate mounted on the amplifier assembly and it is placed in the airflow of the blower motor to provide cooling to the transistors to prevent electrical heat failure. To retrofit wont cost that much. I have done conversions by simply evacuating the R-12, replacing all easily accessed o-ring, draining as much old oil as possible, adding ester conversion oil, and then pulling system into vacuum for 15 minutes. Its going to be 95F today with 63% humidity. Connect center charging hose refrigerant can, break seal of refrigerant can purge air, both valves of gauge stop vacuum pump, and confirm that the reading does not rise.
The picture on the left is what a sight glass looks like. They recommend indoors exhaust vented outside or in a shaded area. If I was back home I would agree with your statement but the heat and humidity kills me here. This can cause a problem if you need a recharge. Its going to be 95F today with 63% humidity.
At 50% humidity on a 95° day the air temperature coming out on Max blower is 62 to 65. Gas evaporates quickly and breathing may become difficult due t o lack oxygen, keep refrigerant away from open flamer because poisonous gas will be produced it, compressed air must never be used clean, slowly open the valves to discharge only refrigerant. I have put a page together on my you fix cars website that has more tips and directions for people that want to to 134a. The first box in chart 1 says check refrigerant level. R-12 is not illegal to use or own at all for those with proper certification.
This also opens a whole can of worms because now instead of a simple charge you need to do a major conversion. Blower motor pushing air through evaporator This allowed for a selection of infinitely variable airflow rates. It stores up extra negative pressure for when the car is not producing it. Charge it while running compressor ease, when low-pressure gauge reading 98 kPa, with can in upright position, monitor sight. Its going to be 95F today with 63% humidity. Then they refer you to a page that has a picture of the sight glass. Re: Fixing an air-conditioner in a '88 Z31.
When the evaporator temperature rises above the specification power is restored to the compressor. I haven't played around with it yet, but that's what the seller informed me of. Throw it in the trash and enjoy the t-tops. Valve, located inside evaporator case, the compressor cycles on and off t o maintain the evaporator temperature within specified range, the evaporator coil temperature falls below a specified point, the thermo control amplifier interrupts, the refrigerant system is protected against excessively high pressure by a pressure relief valve located. My car had 3 open lines, I replaced those and the whole system is working again and stoped shutting hot air inside the vehicle trough the defrost vents.
R-12 is not illegal to use or own at all for those with proper certification. That is not an icy cold output temperature. If the Z blows all air out the defroster you need to check the vacuum system first. Also check to see if your compressor is even running Re: Fixing an air-conditioner in a '88 Z31. To my surprise I did have problems with the air-conditioning system, but never had a refrigerant problem so I never converted the system. If its working one of them should be ice cold. I'm not informed enough to do my own repairs for stuff like that.
