Well, i have to try to revive the old A/C today..... doctor says i may have had a heart attack last weekend, @28... wife has grounded the truck until i get the a/c fixed... i'm trying to unground it something about the texas heat or whatnot

 

i been to texas with not ac i lost 10pounds in 5 days but in keep alot of watter in the truck

 

I took my AC system apart and it was really simple. Just make sure you add the oil to the system if it looks dry and evacuate for 30 min at least. A new accumulator doesn't hurt either.

 

Real texans don't drink water. .......................BEER....................... ...

 

iam form kansas star

 

new compressor, drier, and new blue oriface tube

 

BUT then, i lost my clutch in the middle of the highway across 2 lanes and turning lane.... 5 hours later i got a clutch again

 

dude ur storys allways but a smile on my face

 

well, glad someone gets a kick out of My Life of Murphys Law

 

First of all, what went wrong with the system in the first place? if the compressor failed on you, I would strongly advise inspecting all the lines and parts for any signs of depris in the system. Doesn't take much crap to kill the system.

When I rebuilt my AC, I blew acetone through all the metal parts until it came through completely clean. Let it sit overhight for all the solvent to evacuate, then start reassembling the system. After its all back in the truck, I added the oil and sealed up all the connections. Evacuate as close to 30Hg as possible for a minimum of 1 hour.

Something you can try before adding the oil is to pressurise the system with compressed air for a few days (do not let it actually cycle!!!!!!) and see if it will hold pressure. Its cheaper than having to refill the system twice. Ideally you should also replace all of the seals, but I only did the ones that leaked.

I also used a hydrocarbon refrigerant in mine (duracool) which is a blend of isobutane, butane and propane gas. It works very well but is not legal in most states. If you are using an R134a drop in conversion, then replacing all the seals is more critical and you have to use PAG oil instead of the mineral oil that is used in the original R12.

 

The clutch was locked up and it looked like the pervious owner used it as a punchin block. i have changed out the seals, blown the system out with air, but had a dr appmnt so i didnt have time to get it charged today. 2 uncles are mechanics with the proper equipment to charge the system. also about 6 months ago i put a 30 inch pull on the system, and it held it for 6 hours while we delivered concrete. it still was at 30 when we got off that afternoon. when i blew out the system i got a little bit of dust out of the condenser, and the oriface tube was a little dirty, but it wasnt clogged or anything.

 

As long as the previous compressor didn't internally grenade, then it should be OK. This is one of those things where you can't be too clean and how clean it is will have a direct affect on your success.

In reality the orifice tube should have practically nothing on it, but hopefully all the stuff that was in the system got caught there. Not ideal, but you might get away with it.

 

i probably ran air through it for about 15 mins, got dust for 2-3 and the rest was just for good measure

 

hope u got it fix best of luck hope r wife ungrounds it lol

 

me 2 joe, me 2, doc says he sees something wrong on ekg, now must do a stress test, have to stay cool, rest, little stress, i think i am fixing to start learning gunsmithing
