Campaign No. 2005060017
August 2005
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT:
MODEL 203, MODEL YEAR 2004
INSPECT LATCHING OF LOWER RADIATOR HOSE, REPLACE RADIATOR IF NECESSARY
This Service Campaign has been initiated because DCAG has determined that on the affected vehicles (see VIN range below) the coolant hose at the bottom right of the radiator must be checked to determine whether the two catches of the coolant hose are latched correctly.
Please review the Effective Serial Number chart shown and if necessary repair the subject vehicles during the vehicle's next service.
Prior to performing this Service Campaign:
^ Please check VMI to insure the vehicle is involved and to determine if the vehicle has been previously repaired.
^ Please review the entire Service Campaign bulletin.
Approximately 26 vehicles are affected.
Procedure
WARNING!
Risk of injury to skin and eyes from contact with hot coolant spray. Ensure safety goggles and gloves are worn. Ensure engine is cold prior to inspecting engine cooling system. (refer to WIS document AS20.00-Z-0001-01A)
1. Place vehicle on lift (refer to WIS: AR00.60-P-1000P).
2. Remove lower (front) engine compartment paneling.
3. Visually inspect radiator to determine if the 2 tabs (arrow, Figure 1) on the lower radiator hose (Figure 2) are completely locked into the lower radiator neck (Figure 3):
^ If lower radiator hose tabs (arrow, Figure 3) are completely seated into the lower radiator hose neck; radiator does not require replacement. Reinstall lower (front) engine compartment panel in reverse order. No further work is required; campaign is complete.
^ If radiator hose tabs (arrow, Figure 4) are not completely seated into the lower radiator hose neck; replace radiator (proceed to step 6).
^ If visual inspection is inconclusive, continue with procedure.
