DATE: January 1986 (supersedes 82/37, March 1985) REF. NO. 82/40
SUBJECT: NEW MB WINDSHIELD WASHER CONCENTRATE WITH IMPROVED CLEANING PROPERTIES
NOTE: S.I. 82/37, March 1985 was revised to include the part number of the summer ("S") concentrate. Please discard your copy of 82/37.
New M-B windshield washer concentrates are now available containing an improved cleaner additive. Complaints of windshield wiper smearing should be resolved through the use of the new concentrates (mixed with water according to the directions). When smearing occurs, it is very important to advise the owner to use the windshield washer as often as necessary. A window cleaner should also be used periodically to clean a dirty or oil filmed windshield.
Due to the aerodynamic slope of the windshield, models 124, 126 and 201 exhibit a greater tendency to accumulate road film on the glass. Therefore, we recommend that only the new concentrates be used on these models, depending on the season. On other models, the old fluid may be used up, except in case of smearing complaints.
The part number of the new washer concentrate remains unchanged, but is marked with an additional "W", designating winter or year-round use. The summer concentrate is marked with an "S", designating warm climate and summer use only (no protection against freeze up).
The label on the "W" concentrate lists mixtures only to -14 °C (7 °F). Mixing ratios for colder temperatures are as follows:
1 part concentrate to 2 parts water protects to -20 °C (-4 °F)
1 part concentrate to 1.5 parts water protects to -25 °C (-13 °F)
NOTE: MB windshield washer concentrates "W" and "S" may be mixed. The new washer concentrates should not be mixed with other washer fluids, concentrates, or the previous MB washer concentrate. Remove the old washer fluid from the windshield washer bottle before using the new concentrate.
