Whatever you do wind up doing.... wear goggles when dealing with this stuff...

tyl604, I wish I lived near you, Id end all this nonsense and have you back going again in no time.... Ive probably repaired over 500 A/C systems in my career, somedays in the summer, ill fix 2-3 systems in one day.

its a shame some guys have to over complicate simplicity. I've dealt with this alot in this business. I have customers from other cities come specifically for me to work on their vehicle. because I've shown them with multiple visits, I fix it right, am honest, and don't pull out lexicons, dictionaries, and FSMs spending wasted hours on diagnosis. I use mechanical experience I gained from the military, and running my own shop, that have gotten me through so many messes. you don't know how many times I've come to the same conclusion as fellow techs in the shop, faster, while they plug away in some novel of a manual.

anyhow, I hope you get it fixed.

by the way.... that thread of tylerh860 manual trans conversion...... thats me, my work. he specifically requested my doing the job.

Are you Donald Trump ? Don't need no stinking instructions... will fix it quick without those misleading manuals.... what we do not have is feedback from your customers... how likely are they to come back to a personality like yours if your ' fast ' fix does not last ?

Manual Transmission Conversion for my 1984 300SD

check out my work. no instructions.
I didn't earn Tyler's trust from failed longevity and low intelligence
nor any other of my 1000+ customer base

Unless you are intentionally trolling... you have already said many things which indicate that you do not understand that there is a need for cleanliness inside the refrigeration system.. AND that the physics of moving the correct oil around the system has certain rules which , for instance, do not allow mixing R12 and R134a in the system at the same time... and you did not say if you were correctly using FREON to mean R12... at which time your procedure for checking for a leak is violating the EPA rules...

#51 09-03-2016, 12:24 AM

every system I open for major work gets flushed with denatured alcohol for cleanliness. then reassembled and filled with proper oil, then r134, or 12.
The EPA allows a denimonous amount of leak for leak testing and gauge connect\disconnect

deninomous does not specify an amount, but clarifies it to be kept to a minimum
therefore not a violation to fill for test if intended to repair a leak.

this is hammered into us each year at Kansas city global Vision conference for top tier techs. I never did see you there

#52 09-03-2016, 12:34 AM

I also never said to mix r12 and r134 if his system is empty, then there will be no mix. I also did not tell him to buy freeze12 I just mentioned some products out there. I've never used it, only plain old r12 for r12 systems.
mineral oil in r12, pag in r134

or BG universal that is good for either

You said ''
If you have R12, or a replacement for it... IE Freeze 12 cans, you can fill the system without gauges. Add 1 can to get system going, inspection window will be cloudy white. Keep adding Freon until window turns crystal clear... presto, thats it. DONT add any more. Buy a can of UV dye, usually pressurized in 4 ounce can at parts store. Add to system. Buy a cheap black light. Find the leak yourself easy.... '''

I have asked you repeatedly if you were correctly using the name FREON... which is the Dupont name for R12... you have ignored that question..

You said, as I just copied above ... that if he had Freeze 12 cans he could keep adding FREON until the window turns crystal clear...'''' that is mixing R12 and R134a ... in addition to being incorrect as to the correct way to determine the correct charge in the system.
ALSO , since he said it was an R12 system.. telling him that it was ok to put a primarily R134a blend into the system without evacuating the oil which was used with the R12 was wrong.
AC is simple ...but requires careful attention to the physics details... and associated theory...

LG, it is tiring your insistence that the FSM, EPA and your way is the only way to do AC work. If I have this right, you learned what you know from a lot of reading and research 5 plus years ago, you do not work in HVAC/ MVAC. Things change and some of what you learned is outdated or not applicable anymore. This is a DIY forum and most of us are not mechanics or trained professionals. He is Tyler's mechanic with 30 years experience. I would like to hear what he has to say instead of you constantly bashing people down who has a different way/ idea than what you think is right. Guess who I will trust to work on my AC if I have a choice between you and him?

Again your critical reading skills combined with your contrarian attitude fail you. I have always said that what a person does with or to THEIR car is their business . Recommending non standard or even possibly illegal actions to OTHERS in a thread on the forum is totally different...

I do not care and would not know if a person PM's an OP and suggests those kinds of things...

How is it that you are not able to hear what he has to say ? I am not keeping him from posting and you do not mention the fact that I keep my comments , until he called me a name , to the physics of the situation .

All the things I post are easily cross referenced by consulting other sources. I do my best to only recommend industry standard practices and to warn when other methods are posted... it is only fair to raise a FLAG on those things for people interested in DIY .

I always assume that a person DIY has more interest in doing the job to where the positive effects will last as long as possible... a shop does not have that incentive or the time to execute a job in that fashion most of the time... most AC work is warranted for ONE YEAR..... and many people do not realize that is unnecessarily ( due to short cuts shops are forced to take ) short service out of an AC repair and have no way to do anything about it.

You should have , instead of repeating your predictable opposition to ME... as you have a history of doing... posted YOUR argument/s FOR whatever he said. But you didn't because you know, as much as it pains you , that those manuals and physics rules are valuable assets.... but , being you, I am sure you feel better having attacked me personally this morning...

If I was in the market for AC work as a customer, I would not be going to you leathermang. You can quote all the scriptures from memory that you can, and at the end of the day, if a guy doesnt get his wallet out to pay you because of your staunch, airy, uppety attitude, then your business will fail.... and the "stupid uneducated, non FSM quoting guy" rolls in the cash.
Besides I dont think you even have real world daily experience in ac work, just book knowledge. Ive seen bookworms in this field quote out some bodacious mouth work, but you give them wrenches and say DO IT, they end up stripping out aluminum AC fittings, scrapping out parts, rounding off bolt heads, and running the customers bill sky high. Then they say "oh....the FSM says your supposed to do it this way.. but it didnt quite work out, there must be a quadratic equation somewhere to support my error"

I guarantee you, when you have to explain yourself to the customer, he/she will wear your ass for a hat and give a damn less about your book smarts.

He/She says "FIX MY AC NOW!" They could give 2 craps about EPA compliance, hence your attempts to comply would take excessive time, resources, and loss of customers who go to "Dave the non book guy" because they are tired of your crap.

WOW, take cover. Truth hurts.

I have had 3 comebacks for AC work, count them...3.... for factory defects in parts. There are multiple vehicles that I see over and over for service, and newly arised problems.... guess what... most of them have an AC system that I installed, and they are ALL still working great. One is a Chrysler minivan that I put an AC system in 15 yrs ago, it still cools and holds it charge to this day.

I am friends with several shop owners across Kansas, they all do AC work the same as I do. NONE of them are 100% EPA compliant, 2 of these are dealerships.

tyl604 wants his leak found. He is not interested in complicated processes, nor is he, or any DIY'er so concerned with EPA compliance. I didnt say he should vent his system to the atmosphere.

Since when did ANY DIY guy consult the local Department of Health office or EPA agency to check if they are compliant?

He is a good guy, looking for a hand, not an EPA Nazi shooting FSM directives from his mouth.

As no insult to any member here, most people on here wont even comprehend your complicated advice. They will ignore it and wait for the next guy to chime in. Scaring them doesnt help either.

When I was in the military.... when a Tank broke down, even Uncle Sam himself could give a damn about EPA compliance, we had to have it going ASAP, however we deemed it to happen.

Your methods are over complicated and cannot be instilled within a shop enviornment, much less a DIY scenario.

Leave us alone, go read your books, so we can help tyl604.

Do you not understand that he is making MY argument that DIY have more potential interest in taking the time to do the little stuff having to do with cleanliness , etc ?
A shop does not have that luxury...
that does not mean we should keep that information from DIY owners.
So , Funola and ah-kay attack ME ( and the FSM and EPA rules , really ? ) instead of explaining how the physics supports his statements..... surprise surprise...

Thx.

I see it that your system is probably empty. Go ahead and connect your fill valve and shoot in a small amount. then close off the valve. Listen for any large leak. If nothing heard, then perform visual inspection with soapy water in a spray bottle. Spray all fittings, rubber portions of lines, condenser, and compressor main shaft for leaks.

Your car holds 2.86 lbs, or aprox. 46 oz. r12 . You will have to determine your can size and what not to get the right amount. Fill the system, when you get close to the right amount, your inspection window will go from cloudy white, to clear(with AC running) Combining the window observation, with proper track of how much youve put in, you wont over charge it this way.

Now it should cool. If it leaks fast, soapy water will find it.

If you are worried about EPA violations, you might want to have your system converted over to r134a, as it is commonly bought at most stores.

If the EPA was worried about leaks, then over the counter r134a would be ILLEGAL

Because what does the common consumer do when they have a slow leak... refill, refill, and refill, leaking it all to the atmosphere. Yet you can still buy can after can after can....

EPA and what not is your business. If I were a DIY, I would care less about it. They arent going to spend $15k dollars to send a team out to investigate one car being filled with refridgerant.

I am not advocating breaking the law. I am simply saying, your business is your business. Do what you feel is needed on your car. it is YOUR car, and YOUR choices
