Purpose and Specifications

FEBI BILSTEIN Antifreeze Glaceol RX Type D is a premium coolant formulated for Renault vehicles and other aluminum-engine cars. This 1.5-liter concentrate provides reliable engine protection across a wide temperature range from -35°C to +100°C, ensuring your cooling system stays protected in both freezing winters and hot summers.

This coolant meets Renault Type D specifications, which means it's specifically engineered to protect aluminum engine components from corrosion and rust buildup. The green color makes it easy to identify and monitor coolant levels in your radiator.

When to Use and Replace?

Initial Use: Use this coolant during regular maintenance or when replacing your vehicle's cooling system fluid. Always dilute the concentrate with distilled water in a 50/50 ratio before adding to your radiator.

Replacement Schedule: For Renault vehicles using Type D coolant, plan to change your coolant every 2 to 3 years or around 60,000 kilometers, whichever comes first. If you're switching from factory coolant to this aftermarket option, follow a 5-year replacement interval unless your vehicle's manual specifies otherwise. Check your coolant strength each autumn before cold weather arrives to ensure adequate freeze protection.

When to Replace Immediately: If your coolant appears cloudy, discolored, or rusty, change it right away—these signs indicate the protective additives have degraded and corrosion is occurring inside your engine.

Key Benefits

• Prevents rust and corrosion in aluminum engines
• Maintains consistent engine temperature in extreme conditions

Frequently Asked Questions

Q: Can I mix this with other coolant brands?
A: No. Always use the same coolant type throughout your system. Mixing different brands or types can reduce protection and damage seals. If you must substitute, plan to change the coolant sooner than normal.

Q: How do I know if my coolant needs changing?
A: Check your owner's manual for the recommended interval. If you can't remember when it was last changed, or if it looks cloudy or discolored instead of bright green, change it immediately. Neglecting this can lead to expensive engine damage.

Q: Is this concentrate or ready-to-use?
A: This is a concentrate that must be mixed 50/50 with distilled water before use. One 1.5-liter bottle will make 3 liters of ready-to-use coolant.
