Purpose and Specifications

The FEBI BILSTEIN 22268 is a premium G11 antifreeze concentrate designed to protect your engine's cooling system year-round. This blue concentrate provides three-layer protection: prevents freezing in winter, stops corrosion of metal engine parts, and protects against overheating during summer driving.

This is OE (Original Equipment) quality coolant, meeting the exact standards of major manufacturers including Mercedes-Benz, BMW, Audi, Ford, and Volkswagen. The 5-liter concentrate can be mixed with distilled water in ratios of 50/50, 40/60, or 60/40 depending on your climate.

Key Features

• Freeze Protection: Protects down to -38°C when mixed 50/50 with water
• Corrosion Prevention: Guards against rust and deposits in aluminum and cast iron engine components
• Long Service Life: Typically lasts 3-5 years between replacements
• Foam Resistance: Prevents air bubbles that reduce cooling efficiency
• Universal Compatibility: Approved for Mercedes (MB 325.0, MB 325.2), MAN (324 NF), and Volkswagen/Audi (TL 774-C) vehicles

When to Use / Replace?

Replace your coolant every 3-5 years or according to your vehicle manufacturer's service schedule. Most modern vehicles require coolant replacement between 40,000-80,000 km. Signs you need a coolant change include: discolored or cloudy fluid, visible rust particles, or a sweet smell from the engine bay.

This concentrate is ideal for spring maintenance when preparing for summer driving, or in autumn when preparing for winter conditions. Always use distilled or de-ionized water when mixing—tap water contains minerals that reduce cooling efficiency.

Frequently Asked Questions

Q: Can I mix this with my existing coolant?
A: No. Always drain the old coolant completely before adding this product. Mixing different coolant types can cause chemical reactions that damage your engine.

Q: How do I know if this fits my car?
A: Check your owner's manual for the coolant specification (G11, G12, etc.). This product is G11 and approved for Mercedes, BMW, Audi, Ford, Volkswagen, and other major brands. Verify your vehicle's OE number against the compatibility list.

Q: What's the difference between concentrate and pre-mixed coolant?
A: This concentrate is cheaper and lighter to ship, but requires mixing with water. Pre-mixed versions are ready to use but cost more. Both provide identical protection once properly prepared.
