I just came back from a 1200 miles trip to North California on Memorial W/E and I do not expect so much toxic stuffs on this respectable forum.

I was driving one of my luxury 300SDL for the trip. Before the trip, I top up the p/s with 99 cents p/s fluid. Change the oil and filter with 99 cents engine oil. Running on converted R134a A/C along the way. I did 1200 miles on WVO without a hitch and at $0. My engine, p/s and A/C were fine and I returned home in good shape and relaxed. I stayed in Marriot Hotel and ate out every meal with the money I saved. I have done 20K hassle-free WVO miles on this 300SDL since I had it 1 1/2 year ago, with converted A/C running of course.

I do not sweat at small things now. You can deride me on using cheap stuffs or not knowing anything about A/C. The fact of the matter is that I have converted at least 4 cars to R134a successfully for less than $50 and they are cold. I used R12 before when I changed out the compressor on a Lexus LS400 and the evap on a Chrysler minivan. I use R134a nowadays as they are readily available. I use Harbor Freight vacuum gauge to do my measurements and it serves me well. I would not spend my hard earned $$ on frivolous stuffs, definitely not on auto stuffs. The profit margin on auto accessories are at least 300% if not more on most accessories. I know for a fact that price does not equate to quality in most consumables.

Last by not least, may be I do not understand the members around this forum. They always ask questions like 'My AC is blowing hot air, what can I do?', 'How much oil should be put in the compressor?', 'Can I adjust the pressure switch?' etc. The way I read it is that they want to fix it themself and fix it at minimal costs. If they can afford to take it to the professional then why would anyone post such questions in this forum. I do not know everything but I offered some of my experience and they were my GOOD experience.

Thank you for making answering this post so easy.

In some high stress situations... like the inside of the AC system .. SMALL THINGS DO COUNT...why? because some of the orifices are small... like the TXvalve...and if it gets clogged your ac does not work.

You do not understand the members of this forum who are interested in protecting newer members to any particular mechanical problems from overly simplified statements which can get them into money or physical trouble by believing what they read from someone claiming ' fast easy cheap' solutions which do not exist for long term viability.

I am going to paraphrase Einstein on for the last answer... the ' at minimal costs' part...

He said ' everything should be made as simple as possible...but not simpler'...

'Things should be fixed as cheaply as possible but not more so'...

meaning you have to know where ' cheap' crosses the line to ' cutting corners' which will in fact COST YOU MORE in the long run than you saved initially. If you understand the trade off... that is ONE thing..but to sing out a solution to those who may not know the tradeoffs... without warning them... gets people who do recognize the difference up in arms...

Obviously it didn't, but the following statement in post #1 should have clued you in to the fact that this thread was not about a $50 low-budget, penny-pinching repair job.

I spent $50 NOT because I wanted to. It is because I had to to buy the conversion kit. If I could do it for $0, I would have done it. It is no point to over spent on a 25+ old car, no car is immortal.

If you want to spend as little as possible on your car that is fine. I'm happy it has worked out for you. Don't assume that just because someone is posting here, they are looking for the cheap way out. Sometimes that is the case, sometimes it isn't. The reason people get worked up over your posts is that they come across as saying: "this is the cheapest way to do it and its fine to do it that way." That is not always the case. Let someone make an informed decision. If they want to go the cheap way, that is their choice. If they want to go the more expensive, proper way, that is fine too. The goal is to let the person know the proper way to do something and the risks associated with not going that route.

You just proved his point, without even knowing it.

300% or more profit margin on most auto parts? That's a laugh. Perhaps you are confused with a adult bookstore or head shop, as California has no shortage of those.

I used to own an independent import autoparts store(anyone remember Lazorlite or Bap/Geon

), and I can tell you that the profit margin was closer to 40% on average for retail. Wholsale was less due to more favorable pricing and discount for payin accounts in full every month, not to mention the costs of delivery. Anyways....

The guys that drive the Matco/Snap On/Mac tooltruck will also laugh at your comment, if you meant tools instead of parts. Since you spoke of tools and consumable shop supplies in the same post, it's hard to know exactly what you meant.

Do whatever you want to your own cars, but please stop dipensing advice here as if you are some kind of guru. Some people might get hurt or spend way more than they should because they took your "green engineer" qualifications to be legitimate.

Some of us have forgotten more about the nuances of the auto repair industry than you will ever learn from the internet or interdicknamics.

KrautWagonGTI · #39 06-08-2009, 09:56 PM

Just wanted to let you guys know that my a/c is working amazing!!! Had the system vacuumed down and charged with 134a, the friend that helped me put a thermometer in one of the vents and it was blowing 36 deg F

) My car is so much more comfortable now

) I've never had a car with a/c that worked so well.

rrgrassi · #40 06-09-2009, 12:14 PM

Do not forget that you need barrier type hoses for the 134a stuff. I used the 134a before, and will not again. Higher pressures make more resistance in the turning of the compressor, sapping the already low powered engines. Turbo boost for me it shutting off the compressor while accelerating. Keep in mind this is on the OM617.952. Plus, in Texas, the 134a in the MB cooled well with ambient temps below 85 or at night. It was torture during 100 degree days with 134a in a system not designed for 134a.

The temps here in Florida have been in the high 90's during the day and I have no window tint, This a/c system is kicking ass

The "national chain" store I used to work wholesale at would often easily pull 3x-4x what they got the product for. I couldn't believe how much they used to charge for some of the stuff, though I assume employees and store management were quite a large chunk of the difference. I used to get such good discounts (still do if the old guys are working there). I do commend you for running an honest non-rip-off business like many of the other (now beginning to struggle) indie parts stores.

KrautWagonGTI · #44 06-12-2009, 10:55 PM

My a/c is still working great but I just noticed that the a/c cooling fan is not switching on, I jumped it and the fan itself works. What would cause this?

compress ignite · #45 06-13-2009, 01:42 AM

If you're gonna run R134a in an R12 system you need a Parallel Flow condenser,
it will make up for the 134's lack of heat transfer ability with it's 30% better
transfer performance.IT WILL NOT BE A "Drop In" replacement.

Spend some time "Plundering Around" on Arizona Mobil Air's website:

I'm running BG's FrigiQuiet for an AC lubricant with a reconversion back to R12.
