A/C

Happened to be at www.blackforestllc.com tonight to review progress on my 190 SL.  Was able to observe the finished product of a completely rebuilt A/C system by them on a 113.  This 280 SL had all the guts of the dealer add on A/C system removed and the new owner, wanted the system rebuilt.  Black Forest sourced the very hard to find hoses.  Had them made in the more modern, smaller diameter, superior construction materials (SAE).  The clamps are a double system, virtually guaranteeing no leaks and service ports were added to provide ease in future charging and maintenance.  Fortunately, the condensers were still on the car as well as the underdash evaporator and fan unit.  Tonight was particularly hot and muggy, 80 or so and the system with the car only at idle was blowing less than 50 degree air on full cold and medium fan.  Worked beautifully.  Thought I'd let the community know there is a solution to the black hole of 113 dealer added A/C unit restoration.

Did they keep the original compressor and what coolant did they use?  This would be a good discussion for the proposed Tech Session at Black Forest in October.?
John is this the car we see in pictures at your garage?

The only thing left of the A/C in this car were the condensers and evaporator/fan unit inside the car.  Everything else is new, compressor, hoses, drier, refrigerant.  Can't tell you at the moment the type of refrigerant. Drove the car yesterday in 85+ degree heat and the A/C worked great (for a vintage A/C).


Yes, this is the car you've been seeing in my garage that I'm detailing for my friend.

Concerning Sat./Oct. tech session.  We need to round up some more people and set a date.

If your car has the double belt pulley on the crank or has a York style compressor currently installed, a Sanden 508 rotary compressor is a great choice for replacement.  They are available for about $230 at many A/C suppliers.  

Most local A/C shops can manufacture the hoses necessary.  The trick is matching the fittings on the existing condenser.  I'd suggest finding an old guy who's been at it a while.

You always want a new drier if the system has been open for any significant period of time.  There is a company in Ft. Worth Texas called Old Air Products that rebuilt my drier for $90.  They can supply the compressor and good advice.
