[diesel_mercedes] AC Fun

 


R134 also has a lower working vpressure than does R12 so don't just go tossing cans of R134a in there willy nilly .

When my 240 works it does work good up till about 95 degrees, then its better than outside but not cold anymore just cooler. Hot summer coming. Max

30-years ago, before yards were required to remove the refrigerants, it was not uncommon to come across then 15-, 20-year-old-cars with a full charge of R-12 still in their systems.  If you loosened a connection, or broke or cut a hose, you were in for a surprise...!

When you guys pull a vacuum on the ac system, how long is needed to see the system seems OK?  My neighbor has all that stuff Nate just mentioned, he has taken ac classes, ect.,ect.We have been tru my whole system, the vacuum reads good for as long as we can wait. Fill it up with ac juice, works good for 1 summer. Blah. Leaks out somewhere, old cars . Max P.S. does anyones ac system work year after year with no recharge?

He also damaged the body a bit and didn't install the new Condensor properly so it was rubbing on the body and one bracket was detached.....


I have much work to do , I am now looking at buying an AC vacuum pump to properly evacuate the system , maybe even a pressure pump to better test it before charging .


There's a whole lot more bad news , let your imagination run wild .

On they went after a very small amount of cleaning , this is the good news : in spite of the recent fuel leaks I've had , I am very pleased to see almost ZERO engine oil leaks under neath the car ! this is a happy thing as I've been replacing gaskets and grommets etc. for a while now .


The intake tract had very little oil in it , only on the bottom part , not lightly coated as is common .


I decided to replace the engine shock absorber mounts , the one below the IP was disintegrating (I have a 'photo but my computer suddenly doesn't see it)  , The Classic Center now has the kits very affordably and this includes the hardware , nice as the over sized 6 MM hole flat washersd make dandy problem solvers .


Still no HAVC =8-( , lots more other works to do .

[diesel_mercedes] Freon

 


Just so Mark ;

For a while there they were salvaging the oil R12 and selling it , I wonder how they filtered and de contaminated it ? .

I've been studying up on AC Service since I've not done any since 1986 or so and there's a lot of comments that 20 + year old AC hoses simply degrade and become slightly porous , they recommend either new hoses complete or re using your old ends with new modern typ hose....

We'll see .

I still have to work out what and how the two switches on the receiver-dryer are _supposed_ to work and be connected , fix whatever is wrong there , before I begin to think about flushing the system , new compressor , new hoses and so on .

I no longer remember how to purge the AC Gauges , for example and I know this is very important for satisfactory long term results .

That's a very good idea Brian ~

I've just been connected to a better printer @ work and can now print on both  sides of the paper .

Maybe I should do that too when I get back .

Buy some _decent_ paper too ~ the crap they buy is like 250 % recycled and doesn't print well , falls apart , causes printer jams ,on and on and...

[diesel_mercedes] Phoenix In April

 



I arrived just fine .

It rained quite a bit , the temp. never passed 8* F and there was a stiff breeze all day long .

When I was in my Teens and Twenties , the Az. heat didn't bother me much , now it's bad and I worry about needing to change a tire , we'll see .

I went up the Chiriaco grade @ 102 MPH , 10" of boost and 82* C on the temperature gauge .

The vent hose on the rocker box keeps popping off , not a lot of oil spits out but it bugs me so I ordered up another rubber elbow ~ I already have the special spring clamp .

I left late this morning , got to Bloomington , Ca. before running completely out of fuel @ 573 miles , this returned  27.4 MPG ~ I think that's the best MPG's I've ever gotten out of this Coupe ~ I wasn't on the throttle much , no additives at all .

I cleaned the clear plastic intake screen three times , each time it had those tiny black chunks than when you touch them , *instantly* dissolve into fine jet black paste , no grit to be felt .

I tanked it up and added almost two pints of Startron , I can already see the black chunks collecting dammit .

I may have to remove the fuel sender again to see if fungus has started back growing in there .

I've been running it hard since I filled it up , swerving a lot left and right too , trying to get the cud in the fuel tank to get sucked into the tank screen....

It's *SO* beautiful out here in the Desert . smells nice too because of all the rain .

Diesel here in HOTazona is $1.99 ~ $2.17 .

All I can say is this - maybe 5 or 6 years ago I had to take my wifes car (Martha) to Phoenix at the end of July. My wifes A/C was non-functioning. We left Phoenix and the road temps were 110-115. Blew one tire in AZ, and a 2nd tire outside Blythe. I sweated like a stuck pig changing the tires, my wife thought I was going to die, she got heat stroke outside of Blythe and the ambulance took her back to Blythe Hospital where we spent the next 8 hours. Going to Phoenix in April will be a piece of cake - enjoy the cool breezes.

Re: [diesel_mercedes] Mixing Diesel & Gasoline For Extreme Cold

 

I cant find any mention of adding gas in the 123 manual but on page 84 it has a chart for winterizing diesel by adding kerosene, which is what the fuel companies used to do up here in the frozen north, with a 50/50 mix. I was told several years ago there is some new process they use now, but dont know for sure. max
