Compatibility and Applications

The Bosch 3397011238 is engineered for a wide range of heavy‑duty vehicles. It is commonly used on:

• Scania trucks (models ranging from the G, L, P, R, SPRINT series to the T and T R P lines)
• Chevrolet commercial vehicles
• Mazda and Mercedes‑Benz heavy‑duty chassis that require a twin N71 blade configuration
• Other commercial trucks equipped with a standard wiper arm compatible with the Twin N71 mounting system

Its length of 700 mm (28") makes it suitable for large windshields, ensuring full coverage and optimal wiping performance.

Installation Guide

1. Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and turn off the engine. Open the windshield wiper arm to its maximum extension.
2. Remove the Old Blade: Locate the release latch or pin at the base of the blade. Depress the latch while gently pulling the blade away from the arm. If a spray nozzle is present, disconnect it before removal.
3. Attach the New Blade: Align the mounting flange of the Bosch blade with the wiper arm’s attachment point. Slide the blade into place until you hear a click indicating secure locking.
4. Check Alignment: Ensure that the blade sits flush against the windshield and that the spray nozzle (if applicable) is correctly positioned to deliver fluid along the wiping path.
5. Test Functionality: Activate the wiper system to confirm smooth operation. Observe for any wobbling or uneven contact; adjust as necessary.

Maintenance Tips

• Inspect the silicone strip regularly for signs of wear, such as cracks or loss of elasticity. Replace the blade if any damage is observed.
• Clean the windshield and wiper blades with a mild detergent to remove road grime and prevent streaking.
• Store spare blades in a dry, cool environment to preserve rubber integrity between installations.
