ok my 85 2.8 mpfi origionally came with ac. i live in south louisiana and reallly want to repair restore the ac system. i know it is missing some hard lines but do not know what all else is there or needed. HELP... what are all the components and how does it work. im sure i can figure out the rest i am a equipment mechanic by trade.... please help the temp outside is 93 with a heat index of 100+. it is miserable to drive

 

if you are going to replace it go with the new system that does not use freeon. you will find that it is easier to get now since it is outlawed in Cal and most of the US.
pm me your e-m ail address and i will shoot you the parts of a chiltons that talks about it.

 

it isnt that hot yet..i live in alexanderia...take a pic and put it up so i can see what is missing.i have everything except the compressor

 

also got a 2.8 sittin here if you want it for parts got pulled last month..to put my 350 in

 

i took a closer look at it the only t hing missing is the low pressure hard line from the accumalator to the condensor. the compressor clutch does not spin... is it crap now??. where can i get the low pressure line. i think i will keep it r12( heard it blows colder and i have the cert needed to buy it). also since that hardline is missing does that mean the accumalator is junk because of outside things getting to it or should it be fine???i know it gets alot hotter here later i live in lake charles, but the wife is pregnant and this heat is killing her this summer

 

what would have to be changed to use r134a

 

Since you are missing hoses, the system has been open to the atmosphere for a long time. To start, you need to replace the A/C Compressor, since it is apparently siezed, the accumulator/drier(the silver can by the blower motor), the orifice tube, ad ALL of the seals. The system will have to be back flushed prior to sealing to make sure that you have no junk in it. Do this before you install the new parts.

Since the system is basically new, all you'll need to do is install the correct amount of PAG oil instead of mineral oil. Vacuum the system down with the proper pump to remove any leftover moisture and impurities, then fill with the correct amount of R134a. remember that you'll have to convert all the fittings over to the new quick connects.

 

well i got all of it if you need it..just no compressor only 45 min from me

 

Some good budget tips on this page.

snowman is your system all sealed up? if so how much would u be asking for the accumalator and the low pressure hard line....
to change to 134 how do i change the fittings and the only other difference is to use pag oil? does it hold the same amount of 134 as r12. how much pag oil??? thanks for all the help
