• Contains DuPont™ Kevlar fibre and liquid glass resin for the ultimate permanent water tight seal
• Stops leaks from small pinholes (up to 0.8mm diameter) and small cracks (up to 0.8mm width) in any cooling system
• Saves costly mechanical repairs
• Maintains cooling system pressure and temperature to prevent overheating
• Safe to use with all types of glycol anti-freeze/anti-boil coolants and water based corrosion inhibitors

How to Use:

• This product is formulated to be added to the Radiator – Do not add to engine oil.
• If your coolant is dirty flush the coolant and replace with the correct recommended coolant, before adding this product.

Danger: 

Ensure the radiator is cool before opening the radiator cap to prevent scalding. Make sure when adding Permanent Head Gasket Repair radiator fluid is above internal radiator core.

1. Shake bottle contents and pour Permanent Head Gasket Repair made with DuPont Kevlar fibre directly into the radiator. If using in a small capacity radiator (4 cyl) use half a bottle to prevent overflow.
2. Fill radiator and overflow tank to correct level and replace radiator cap.
3. Start the engine and turn the heater to hot and fans to high to circulate coolant.
4. Leave vehicle to idle for 15 minutes.
5. Turn engine off and allow the engine to cool.
6. Check coolant level and top-up if needed. Drive the vehicle as normal.

How Much to Use:

• 4 cylinder engines smaller than 5 litres cooling system capacity use half a bottle.
• 6 and 8 cylinder engines up to 15 litres cooling system capacity use one bottle.
• For larger cooling systems use half bottle per 7.5 litres of radiator capacity.

First Aid Instructions:

• For advice, contact a Poisons Information Centre.
• Or contact a doctor immediately.
