Arrow Radiator Flush

Restore your cooling system's efficiency and prevent overheating with ARROW Radiator Flush. Designed for instant car care maintenance, this specialized cleaner safely removes harmful rust, scale, and deposits that build up over time. By thoroughly clearing out the cooling system, it improves heat transfer, boosts overall engine performance, and ensures your new coolant can protect your engine effectively.

• Deep System Cleaning: Actively cleans rust, scale, and stubborn deposits from the radiator and internal cooling passages.
• Restores Efficiency: Improves heat transfer capabilities, enhancing overall cooling system efficiency to help prevent engine overheating.
• Corrosion Protection: Aids in mitigating further corrosion by providing a clean baseline for fresh antifreeze/coolant.
• Optimal Preparation: Perfectly prepares the cooling system for a fresh coolant application, ensuring maximum lifespan for the new fluid.

For best results, use immediately before a scheduled coolant change:

1. Ensure the engine is **cool** before removing the radiator cap and adding the flush.
2. Pour the entire 300ml contents directly into the radiator.
3. Start the vehicle and run the engine for **10 to 15 minutes** to thoroughly circulate the cleaner through the system.
4. Turn off the engine, let it safely cool, drain the cooling system completely, and refill with fresh coolant.

• DO NOT DRIVE the vehicle while the flush is in the cooling system.
• Use only immediately before a coolant change. (Note: The printed label contains a misprint referencing an oil change; this product must be used in the cooling system, not the engine oil).
• Keep out of reach of children and avoid contact with skin and eyes.
