Bar’s Leaks Liquid Aluminum is part of our next-generation stop leak lineup that not only seals leaks， but also conditions the system. With this formula， you’re getting a solution to your immediate problem plus a preventive tool for avoiding future issues with heater core leaks and coolant leaks. This product also contains Xtreme Cool™， which stops overheating and significantly decreases water temperature. The combination of these two elements are guaranteed to safely and easily seal leaks in plastic， aluminum and metal radiators， heater cores， gaskets and freeze plugs.

Product Features:

• Safely Seals Leaks in Plastic， Aluminum， and Metal Radiators
• Safely Seals Leaks in Heater Cores， Gaskets， and Freeze Plugs
• Contains Xtreme Cool

Directions:

1. Allow engine to cool. Make sure engine is cool enough so radiator cap can be safely removed.
2. Shake well. Pour Bar’s Leaks Liquid Aluminum directly into radiator. One bottle treats systems up to 4 gallons. Use 1/2 bottle in 3 and 4 cylinder engines. TIP: If direct access to radiator is not available， install in overflow tank.
3. Fill radiator and overflow tank to proper level and reinstall radiator cap.
4. Drive/idle engine for 15 to 20 minutes. If leak continues， second application may be required or mechanical attention is needed. For severe leaks， like a blown head gasket， it is recommended to use Bar’s Leaks Head Gasket Fix or Blown Head Gasket Repair.
5. Leave Bar’s Leaks Liquid Aluminum in cooling system for continued protection.
