See reply #4 to your "Other" post about W124 Evaporator R+R feasibility.
BUT,maybe with a SawsAll you can get it out through the Engine compartment ?
HINT: Look over just to the right of the Brake Booster
(Between the Two firewalls)
You'll see the Expansion Valve [Connected to the Evaporator's Pipes]
It is POSSIBLE to R+R the Expansion Valve by itself (BUT it's a WITCH!)
There's a guy at an independent shop in Broward county on a 'Net Video and
it takes him 10+ hours to R+R the EVAP.(and he's done a couple of hundred)
Nate,
GSXR has pictures of one of his W124s with the Blower fan removed and he's
sprayed "No Rinse" Condensor/Evaporator cleaner on his Evaporator fins.
(It just drains out the two tubes at the bottom of the Evaporator Case.)
