- Change Serpentine Belt 2011 e350 Mercedes 2011 e350 4Matic Mercedes Serpentine Belt. 17mm socket & Rachet.
Below is a detailed guide on the process, including the necessary tools and descriptions.
### Tools Required
– **Socket Set**:
– Includes various sizes (metric) for removing bolts and nuts. Common sizes for suspension components are typically 10mm, 13mm, and 17mm.
– **Torque Wrench**:
– Used to ensure that all bolts are tightened to the manufacturer’s specified torque settings, which is crucial for safety and performance.
– **Pry Bar**:
– Useful for levering components apart when there is tension in the suspension system.
– **Spring Compressor**:
– A device that safely compresses the coil spring to prevent it from flying off when removing the strut assembly.
– **Impact Wrench (optional)**:
– Speeds up the removal of stubborn bolts and nuts but requires care to avoid over-torquing.
– **Jack and Jack Stands**:
– A hydraulic floor jack is necessary to lift the vehicle, and jack stands are required for safety to support the vehicle securely.
– **Wheel Chocks**:
– To prevent the vehicle from rolling when lifted.
– **Clean Rags**:
– For cleaning parts and wiping down surfaces.
– **Lubricant or Anti-Seize Compound**:
– Helps in loosening bolts and prevents rusting.
### Replacement Procedure
– **Preparation**:
– Park the vehicle on a flat surface and engage the parking brake. Place wheel chocks behind the rear wheels to prevent rolling.
– **Lifting the Vehicle**:
– Use the hydraulic jack to lift the front or rear end of the vehicle (depending on which dampers are being replaced) and place jack stands under the vehicle for safety.
– **Removing the Wheels**:
– Use a socket wrench to remove the lug nuts and take off the wheels to access the suspension components.
– **Removing the Damper**:
– Locate the top and bottom mounting points of the damper (shock absorber).
– Remove the top mounting bolt(s) using the socket set. Depending on the design, you may need to hold the damper shaft with an additional tool to prevent it from spinning.
– At the bottom, remove the bolts securing the damper to the lower control arm or axle housing. Use a pry bar if necessary to create space.
– **Compressing the Coil Spring** (if applicable):
– If you’re replacing the front dampers, you’ll likely need to remove the strut assembly. Use a spring compressor to safely compress the coil spring before proceeding. Follow the compressor’s instructions to avoid accidents.
– **Separating the Strut Assembly**:
– Once the spring is compressed, remove the top nut holding the strut to the mount. Carefully remove the strut assembly from the vehicle.
– **Installing the New Damper**:
– If you removed a strut, replace the old damper with the new one by reversing the steps used for removal. Ensure that the new damper is properly seated in the strut assembly.
– If just replacing the damper, install the new damper in the reverse order of removal, ensuring it is aligned correctly.
– **Reinstalling the Strut Assembly**:
– Position the strut assembly back into its location, securing it with the top
and bottom bolts. Use the torque wrench to tighten all fasteners to the manufacturer’s specified torque settings.
– **Reinstalling the Wheels**:
– Place the wheels back on and hand-tighten the lug nuts. Once the vehicle is lowered, use the torque wrench to tighten the lug nuts to the specified torque.
– **Lowering the Vehicle**:
– Carefully remove the jack stands and lower the vehicle back to the ground using the hydraulic jack.
– **Final Inspection**:
– Check all connections, bolts, and ensure everything is secure. Test the suspension by pressing down on each corner of the vehicle to ensure proper damping.
– **Test Drive**:
– Take the vehicle for a short test drive to check for any unusual noises or handling issues. Inspect the work done after the drive to ensure everything is functioning correctly.
### Safety Precautions
– Always wear safety glasses and gloves when working on vehicles.
– Ensure that the vehicle is properly supported on jack stands before working underneath.
– Be cautious with compressed springs; they can be dangerous if not handled correctly.
Following these steps and using the appropriate tools will help ensure a successful suspension damper replacement on your Mercedes Benz E-Class E350 W212 BlueTEC.
The brake pedal switch is a crucial component in a vehicle’s braking system, designed to enhance both safety and functionality. Located near the brake pedal, this switch is activated when the driver presses down on the brake pedal. Its primary role is to signal various systems within the vehicle that the brakes are engaged, enabling crucial functions such as the activation of brake lights. When the brake pedal is depressed, the switch closes the electrical circuit, illuminating the rear brake lights to alert following drivers that the vehicle is slowing down or stopping. This visibility is vital for preventing rear-end collisions.
In addition to lighting up the brake lights, the brake pedal switch plays a significant role in the operation of other systems. For example, in many modern vehicles, it is integrated with the cruise control system, disabling cruise control when the brake is applied to ensure that the vehicle slows down appropriately when needed. Moreover, it may also interact with the vehicle’s anti-lock braking system (ABS), ensuring that the system can respond effectively during emergency braking situations.
The brake pedal switch is typically a simple mechanical or electronic device, but its reliability is paramount. A malfunctioning switch can lead to brake lights that fail to illuminate, potentially creating hazardous driving conditions. Regular inspection and maintenance of the brake pedal switch are essential for ensuring optimal safety and performance of the vehicle.
