Flush Interval

Maintaining your Metris's cooling system is crucial for longevity and performance. Mercedes-Benz generally recommends the following flush intervals:

• Normal Duty: Replace coolant every 15 years or 150,000 miles, whichever comes first.
• Severe Duty (e.g., heavy towing, extreme climates, frequent short trips): Consider replacing coolant more frequently, possibly every 5 years or 50,000 miles, in line with general severe service recommendations for cooling systems, though Mercedes-Benz's long-life coolants aim to extend this significantly.

Always consult your owner's manual for the most accurate and up-to-date service schedule specific to your vehicle.

How to Refill & Bleed

Refilling and bleeding the cooling system on your Mercedes-Benz Metris is important to prevent air pockets that can cause overheating. While a professional job is always recommended, here are the general steps:

1. Drain: With the engine cool, remove the radiator drain plug (if equipped) and/or disconnect the lower radiator hose to drain the old coolant into a suitable container.
2. Flush (Optional but Recommended): Flush the system with distilled water until it runs clear. Some prefer to use a specialized cooling system flush product according to product instructions.
3. Reconnect & Refill: Reconnect hoses and close the drain plug. Slowly pour the correct Mercedes-Benz approved 50/50 coolant mix into the expansion tank.
4. Bleed: Start the engine with the heater set to full hot and the fan on low. Leave the expansion tank cap off. As the engine warms up, the thermostat will open, and air will be purged from the system. You may see the coolant level drop; continue to top it off to the
