Use Liquid Glass To Seal A Blown Head Gasket

Start your vehicle and pour the entire bottle of Liquid Glass into your radiator. Allow your vehicle to get up to regular operating temperature. Shut off the vehicle. Place your catch pan under the front of your vehicle where the release cap is for your radiator drain.

Unscrew the radiator drain valve and allow it to drain completely into the catch pan once the vehicle has cooled. Dispose of the drainage as your local laws require. Replace the drain cap and refill your radiator with water. Start your vehicle and allow it to run until it has reached regular operating temperature, then shut it off again.

Again replace the catch pan under the release valve for your radiator, and unscrew the valve. Allow all the water to drain, and dispose of it as law requires. For the last time, replace the cap and refill your radiator completely. You have now sealed up any places in your head that may have allowed a leak.
