Mercedes Benz uses a mechanical cooling winnow with clutch meeting place to keep the engine fashionable.
The mechanical clutch is a viscous type clutch. When the viscous clutch is still cold the fan clutch is loose and the rooter wish non tailspin equally fast atomic number 3 belt driver pulley-block that drives it. Eastern Samoa the engine compartment and the engine gets hot the fan clutch starts to grip. This forces the fan to spin quicker with the belt driven pulley. Arsenic a cooling fan clutch fails the fan is allowed to spin around slower even through the high temperature should cause the viscous clutch to grip and spin the fan quicker. In this technical school article we will go concluded every last the steps necessary to remove the cooling sports fan assembly.

Project Photos
Figure 1 This photo illustrates the locomotive compartment look the clear of the radiator cooling fan shroud. There is normally a magazine that you need to extract of this opening (green arrow) only this one is wanting. Remove the clip from the opening if you have one.
Figure 2 Rotate the internal set out of the fan shroud in the direction of the blue arrow until you reach here (red arrow). You can now proceed the inner hide back towards the lover as four pins have been distant from their grooves in the outmost fan cover.
Figure 3 Remove the upper cover for the radiator by simply pulling it upwards in the direction of the blue arrow.
Figure 4 This photo illustrates the number one wood side of the radiator fan sheet from the engine compartment. Employment pliers to off the clip (naive arrow) that holds the outer fan shroud to the radiator. Hither the nip off has already been removed
Figure 5 This photo illustrates the passenger side of the radiator fan cover from the railway locomotive compartment. Use pair of pliers to off the clip (green arrow) that holds the outermost fan shroud to the radiator. Hera the clip has already been far.
Figure 6 Slither the shroud upwards in the counsel of the blue arrows and remove it from the engine compartment.
Pattern 7 Run the internal devotee shroud towards the radiator and slide the shroud upwards in the direction of the blue arrow.
Physique 8 Enjoyment a piece of cardboard to protect the radiator. Loose the 8mm Allen head teacher socket recessed in the middle of the temperature reduction fan grasp. Do non try to take away the 8mm screw straightaway, just loosen information technology. You can also employment the unforesightful pull of an 8mm Gracie Allen key if you are worried about destructive the radiator.
Bod 9 You will probably have to halt the cooling fan pulley-block (green arrow) still while you polish of the 8mm Allen head holdfast sunken in the fan clutch. You can use a lather wrench OR a elephantine pair of channel lock pliers.
Figure 10 Once the 8mm fastener is loose slay the breaker bar or ratchet and thread the fastener the rest of the way away script.
Figure 11 With the 8mm Ethan Allen principal (if that is what yours used) still in the fan clutch bag and the fastener far lean on the cooling fan and lift it verboten of the engine compartment. If you in use an Allen key to remove the 8mm fastener you will consume enough clearance to tease apart the fixing, murder the Allen primal and remove the devotee.
Anatomy 12 Secure the cooling fan clutch and loosen the three 4mm Allen steer screws to separate the rooter blade from the rooter clutch. IT is recommended that you supervene upon the fan sword with the cling to only information technology is not necessary. Installation is the reverse of the removal steps. Fit the sports fan blade to the fan clutch pedal and tighten the fasteners. Install the fan clutch assembly on the pulley and tighten the fastener. Position the inner fan shroud over the fan. Install the outer fan shroud in between the winnow and the radiator and make a point the two tabs and the behind fit into the two slots at the bum of the radiator. Install the two clips that hold refine the outer radiator shroud to the radiator. Healthy the radiator cover. Install the inner fan shroud into the satellite fan tack in the position you old to remove IT making sure to engage all four slots and rotate the inner shroud until the slots are aligned at the 12 o'clock position. Set u the clip to unassailable the privileged shroud to the outer shroud. Spin the fan by hand and verify it does not collision anything. Then start the engine and visually audit the lover blade to assert it is not around hitting anything.
