Acc Servo

Can a 450 SEL run properly without an ACC SERVO (Can it be bypassed?)

The ACC servo handles all aspects of A/C control, but has no part in the running of the car except to contain the coolant. Other than being a huge coolant leak without it, it won't change to way the car runs.

What's going on, is the servo cracked and leaking?

You could use some kind of connector to splice together the main coolant lines going into and out of the servo, and that will bypass the whole servo/heat system of the car. Of course you'll get pretty darn cold this winter!

See if you can get in touch with CTaylor738. He knows of a guy that is a guru on these things. You should find him surfing the forum often.

Best deal on servos is the rebuilt OEM unit for $295 from George Murphy (Performance Analysis Co.) at 865.482.9175. You should also pop the $50 for a rebuilt amplifier. I put these in my 380SL this week and they brought the system back to life.

You can bypass the servo with a 5/8" hose coupling from Home Despot, connecting the coolant feed and return lines.

George will also send you an excellent guide to troubleshooting the system with the rebuilt servo, or for $5 by itself.

Trivia - this system was developed by Chrysler and licensed by Mrecedes. Chrysler bailed in 1978, but MB kept using them until 1981. You read the description and marvel at how it ever worked.
