[W126 Coupe] Repairs

[Dick Spellman]

Sir Guy:

Motor Mounts:  if the engine is rocking in the cradle at idle or if you get 
a vibration on accelerating and it is obvious that the mounts have collapsed 
it's worthwhile to get them done.  But, you can drive with poor mounts (the 
engine will not fall through to the earth) for an extended period of time.

Linkage bushing:  need a specific linkage or bushing by name or location to 
answer this

Hydraulic fluid:  Brakes.  car on a lift, brake fluid reservoir drained off 
to a couple mm, pressurized vessel with new Dot 4 Plus attached and then 
just bleed until new fluid flows off each caliper in this order.  Passenger 
rear, driver rear, passenger front, driver front.  Total time less than an 
hour and typically done once a year (MB suggests Spring as best time) I'd do 
it now if you are not sure when and if it was ever done to prevent premature 
failure of costly brake components.

Fuel injection cleaning:  sure, why not if it smoothes out a rough idle or 
improves acceleration performance great.  Drop a can of BG-44 in the fuel 
tank and go.  If you are going for a more sophisticated injector cleaning 
where they check spray pattern and the whole nine yards, I'd ask how much 
and see if it equates to the replacement costs of new injectors, seals and 
whatnot first.

My parting thoughts, are you using a MB dealership or a reputable 
independent MB mechanic?
