W210 E320 Wagon SLS Fluid Flush Procedures

Introduction

Welcome to Grafco Electric, your go-to resource for all things related to your W210 E320 Wagon. In this guide, we will provide you with comprehensive instructions on how to perform SLS fluid flush procedures for your vehicle's suspension system. By following these steps, you can ensure the optimal performance and longevity of your SLS system.

What is SLS?

The Self-Leveling Suspension (SLS) is a unique feature in the W210 E320 Wagon that helps maintain a constant ride height regardless of load or road conditions. It utilizes a hydraulic system, consisting of several components, to adjust the height of the vehicle automatically.

Why is SLS Fluid Flush Important?

Over time, the SLS fluid in your W210 E320 Wagon can become contaminated with debris and show signs of degradation. This can lead to a decline in the system's performance and even cause potential damage to other suspension components. Performing regular SLS fluid flush procedures is crucial to maintaining the integrity of your SLS system.

Step-by-Step SLS Fluid Flush Procedures

Before starting the SLS fluid flush, ensure you have the necessary tools and supplies:

• Jack or lift for vehicle support
• Fluid catch basin
• New SLS fluid
• Wrench or socket set
• Litmus paper

Here are the step-by-step procedures:

Step 1: Preparing the Vehicle

Park your W210 E320 Wagon on a level surface and engage the parking brake. Lift the vehicle using a jack or lift to gain access to the SLS reservoir and hydraulic lines.

Step 2: Draining the Old Fluid

Place a fluid catch basin underneath the SLS fluid reservoir. Locate the drain plug on the reservoir and remove it using a wrench or socket set. Allow the old fluid to drain completely into the catch basin.

Step 3: Refilling with New Fluid

After draining the old fluid, clean the drain plug and reinsert it into the reservoir. Proceed to refill the reservoir with new SLS fluid until it reaches the recommended level. Use the litmus paper to check the fluid's acidity level, ensuring it falls within the manufacturer's specifications.

Step 4: Bleeding the System

To remove any air bubbles from the SLS system, start the engine and let it idle for a few minutes. Turn the steering wheel from lock to lock to assist in bleeding the system. Check for any leaks or abnormal noises during this process.
