My electric auxiliary fan had been making more noise than usual this year, so I finally got around to changing it (sure is nice to have a parts car to swipe this stuff from, lol... and, uh, sorry Rusty!) Anyway, I found the mother of all dust bunnies hiding behind the fan:
http://www.w124performance.com/images/W124_stuff/condenser_crud.jpg There was a decent amount of bug parts everywhere else too. I picked out all the big stuff, brushed the fins with a toothbrush, un-bent the fins with a small screwdriver, and then blew things clean with compressed air (sorry, forgot to take an "after" photo.) I had the radiator out this past winter when the engine was pulled so I know things were clean betwixt that and the condenser, but if you have never pulled your radiator, TRUST ME, there is a pile of crap hidden that will shock you. This affects both cooling system performance as well as A/C performance, so it's worth a look! :-) Best regards, -- Dave M. Boise, ID 1994 E500 - 94kmi (Q-ship) 1987 300D - 258kmi (Sportline)
