What It Helps Fix

• Missing washer fluid reservoir cap
• Cracked or brittle cap that no longer seals properly
• Washer fluid loss from the reservoir opening
• Contamination entering the washer tank
• Incorrect cap fit on a 75mm Mercedes-Benz reservoir

Installation Notes

Verify the reservoir opening diameter before ordering; this part is for 75mm filler neck applications. Check whether your Mercedes-Benz uses a heated windshield washer system and confirm any chassis breakpoints or original reservoir numbers listed in the fitment notes. Part number 3126 should be matched to the vehicle’s reservoir style for proper fit.

Quality Assurance

MTC Ronak part 3126 is cataloged as a replacement washer fluid reservoir cap for Mercedes-Benz applications with detailed OE-style interchange references. Use the fitment notes to confirm the correct reservoir configuration before installation.
