First ones I ever did on one of these engines. I was scared to do them, but the 
few that gave me difficulty came out well with some very careful “back and 
forth” work on them as well as soaking with Kroil in advance for about a week.

Re: [MBZ] AC work this past weekend

[Scott Ritchey via Mercedes]

As I recall, I used Cliplight on my home heat pump when I had a leaky 
evaporator.  Then it ran fine during summer but the leak gradually grew worse 
during heating season (much higher pressure).  I was impressed by how well it 
worked.  If my 126 evaporator leaked I'd use that as long as possible vs 
pulling the evaporator.  I plan to get that SD back on the road soon, meaning 
AC will be required.

Say what you will, but I’ve had ClipLight Super Seal fix leaks in AC systems on 
cars here in Florida, and they’ve lasted 2-4 years or more. Only stuff I would 
consider using. That’s even for nasty ones like W140 evaporator leaks.

The other thing you have to deal with is the porosity of the original hoses, as 
they weren’t barrier style hoses. That’s the cause for the annual “top off” 
that many older systems often need.

I had a 1982 300SD I put almost 200k on over a four year period. When I got it 
I put barrier style hoses on it and completely rebuilt the system, everything 
but a new evaporator. In the four years I owned it I put exactly six ounces of 
refrigerant (R-134a) into the system, and that was more as a precaution than a 
need. It made ice cubes in the hottest weather.

Re: [MBZ] AC work this past weekend

[Allan Streib via Mercedes]

Yes as long as you aren't expecting miracles. I had my home HVAC guy use some 
leak sealer on my system that required a recharge every other summer. It worked 
for a few more years but eventually I had to replace the evaporator which was 
20 years old.

I don't know the brand names. Dan mentioned ClipLight also so I would go with 
that.

Ah, well there's been at least two glow plug jobs recently then, so that's 
good, probably won't have any stuck glow plugs.

Agree, but if you can get through another season or two without pulling the

Re: [MBZ] AC work this past weekend

[Max Dillon via Mercedes]

I think Pierre has an opinion on that, you can probably guess.

His advice was too make sure you got the proper manifold o-rings for the GM 
compressor, they have some metal in them.

I think you can get standard GM compressor and flip the rear cap around to make 
the oil flow correct for the upside down install in the Benz, save a few 
bennies?  There is some trick to using those old compressors.

Re: [MBZ] AC work this past weekend

[dan penoff.com via Mercedes]

Say what you will, but I’ve had ClipLight Super Seal fix leaks in AC systems on 
cars here in Florida, and they’ve lasted 2-4 years or more. Only stuff I would 
consider using. That’s even for nasty ones like W140 evaporator leaks.

The other thing you have to deal with is the porosity of the original hoses, as 
they weren’t barrier style hoses. That’s the cause for the annual “top off” 
that many older systems often need.

I had a 1982 300SD I put almost 200k on over a four year period. When I got it 
I put barrier style hoses on it and completely rebuilt the system, everything 
but a new evaporator. In the four years I owned it I put exactly six ounces of 
refrigerant (R-134a) into the system, and that was more as a precaution than a 
need. It made ice cubes in the hottest weather.

The AC was not working and I knew that going into the deal.  

But now that you mention it, one of the glow plugs has died, so I need to do 
that job now.  Dan's son or the previous owner had just paid for that job, 
there was a receipt with the car, but I'll bet the garage that did that used 
some cheap brand of plugs.

That would be the "KlimaKit" conversion? Are there any others?

Anyone have any experience with the Nissens compressors?

Re: [MBZ] AC work this past weekend

[Allan Streib via Mercedes]

I've always been told they are a bandaid at best. Permanent repair of a leak 
will require replacing the leaking part(s) (and even that is not really 
permanent. All AC systems eventually leak).

That said, some products are probably better than others, and may slow or stop 
a small leak for a while.

Only weird thing is that the recirculation function doesn't work.  Press
the button and the light comes on while you hold the button down, but as

could be a bad switch I suppose or might be the PBU.

I’m thinking we put a can of sealant into that system a while back. The good 
stuff, too.

Yeah, last summer I put some test refrigerant in and got out the sniffer,
and no sign at all of leakage from the evap.  I should probably test it
again now, just to be sure.

[MBZ] AC work this past weekend

[Meade Dillon via Mercedes]

Finally got hot enough for me to decide to fix the AC in the '95 E300 I
bought from Dan a couple years ago.  Took all of an hour, if that, to get
the compressor out (front seal was leaking).  After removing the wiper
washer fluid tank and loosening the serpentine belt, I had easy access from
above to get all four bolts loose, remove the manifold connection, and also
the electrical connection on top of the compressor.

And then OCD takes over, and I spent about 5 hours cleaning off the
compressor, carefully opening it up, carefully taking it completely apart
and replacing every seal and o-ring, and using the proper PAG-46 oil
filling it back up with oil. There was some nastiness on the valve plates,
kind of burned looking, like maybe the compressor was run low on oil or
something.  If this thing dies, I'll have to spring for a new compressor I
guess.  Rebuilt two other compressors and never saw anything like this.

The nice thing about these Denso compressors, 10PA-15, is the only special
tool required is a belt wrench or a chain wrench to hold the clutch while
you loosen the front nut, and then a shaft seal sleave to cover the
compressor shaft splines as you press the front case back on with the new
shaft seal.

Popped that back in, replaced the filter/dryer, then vacuum and fill the
system up.  Took me about 8 hours all together, but ICE COLD AC is now back.

Only weird thing is that the recirculation function doesn't work.  Press
the button and the light comes on while you hold the button down, but as
soon as you let go, the light goes out.  Not able to troubleshoot that yet,
could be a bad switch I suppose or might be the PBU.
