Zcurves, what else did you upgrade to be able to us R134?

Zcurves, your the man,, yes, we talked about it last year but didn't finish it up and this year i'm going at it again, im going to install a new drier, condensor and high pressure sensor to get the ac going. Thanks

Leon, i'm searching and every where I have searched has said the same thing you have, and also what fifthhorsemann said is scarring me from trying an electric fan. The reason i'm trying to replace it is because my ac cools when i'm driving but when i come to a stop it doesn't cool as much, i was thinking that if I could more air to the condensor the problem should go away, but now im looking at changing the condensor and changing out the fan clutch. Thanks

Yes, i'm doing some search, I have seen some kits that they sell that comes with a relay just don't know how it is run or where its run. Thanks

Has some one installed an electric fan on their 280z? I'm going to be replacing all of the ac components this summer on my 280z and was also wanting to replace the fan because I beleive that my clutch fan is going out and I would like to upgrade it to an electric fan. If some one here has done this before could you guide me thrue the process? Thanks

hr369, you nailed it, im talking about the fine filter that goes inside the high pressure line. Does some know the part # of it?

no, im talking about the filter or screen that goes in the hose that comes from the ac drier, that same hose goes in the fire wall, inside that hose the filter goes in there. Thanks,

People I want to get my ac working on car again. Lost summer I tried to get it up and running but didn't have much luck, and summer is comming back and I would like to get it up and working, I read several post here and read one that said to buy a drier from autozone part #3318, a high pressure switch part #35758 and a harness connector part # 37219. I called autozone and order all 3 parts, now I just need to order the strainer (orfice)but don't know where to get one. If some one could give me the info I would appreciate it. Thanks

Guys, im stuck with a flat tire, I have a 1978 280z with 14 all around, My back tire got a big slash on the sidewall and i'm stuck becaus no one in town sells 215/60r14. I found some tire shops that can get it for $105 each, but I looked at discount tire and the have the rim and tire packages and I was wondering if I could go with (P195/65R-15). I would like to go wider on the back but just don't know what size of tire I can put on the back. My car was lowered 1 1/5 inch and it has the illumina shocks. Everything else is original. Could some one please tell me what they are running with a lower z, I know that this has been brought up several times but, I just don't have the time to look because I'm getting the car tow as we speak and need to make a decision pretty quick. Thanks

Guys, i'm still confuse about the ac on my 1978 280z, My 280z seems to have 2 switches, one is on the drier and the second is on the line that connects to the drier. Is one of the switches the low pressure and the other the high pressure switch? TTACH] Heres some pictures. Thanks

sblake, thanks for the quick response, well my pressure switch isn't connected to anything, the ac did blow a bit cold but I tried to add some more r-12 and made it worst, now it won't blow cold at all. sblake if the pressure swithc aint working or isn't connected can I still charge the system? Thanks

Guys, I have a 1978 280z that i'm having trouble charging with r-12, It has all the original components but it won't charge up. The low side won't go pass 15 psi and the high side starts to climb all the way up. Last night I was checking out the system and noticed that the ac drier has a some type of sensor. I don't know what this sensor is and where it should connect to, my drier has the sensor on it but the cables seem to be broken off, Can some one please tell me what this sensor is? Thanks

sblake01 and Andrew, thanks a lot for your help, I really appreciate it, I got it now and will be taking on this project tomorrow, hopefully it will be cold enough, but now im starting to believe that it isn't much that I might need r12 but that the blower needs to blow more? I hope this makes sense, i'm going to charge it up and if its cold in the vents but not cooling than I might just change out the condensor and the blower and the dryer. Thanks again for all your help.

sblake01, when you say to check my readings with both valves close do you mean the quick connects or the valves at the actual manifold? Thanks

Thanks sblake01 for all your help, would you happen to know why my ac gauge on the low side goes to retard when I open both the low side and high side on the quick connects but it will read fine if I close the high side from the ac gauge? Maybe i'm doing something wrong? Well what i'm doing is first I connected the adapters to the compressor and yes I had the low side and high side correct then I connected the ac gauge quick connects to the compressor and I open them up from the quick connects and then I open up the valves from the gauge to read the readings. I know that when I try to charge it I should close the high side from the ac gauge. Well sblake01 if i'm doing something wrong please let me know, I just have to get it working because its hot here in texas.
