Steel Seal - Blown Headgasket Repair in 3 Easy Steps...
1. Make sure the engine is cold and remove the radiator cap. Pour Steel Seal directly into the radiator. Tighten the radiator cap back on. Ensure coolant is present before running the engine. If you have drained the coolant out, pour Steel Seal into the system and top up with coolant and move to step two.
2. Turn the heater and fan to maximum. Start the engine and run your vehicle up to temperature (please note this can take between 15-25 minutes depending on the condition of your vehicle). Once your vehicle reaches operating temperature run for 30 minutes. Turn off vehicle and allow to cool completely. Top up with antifreeze/water as necessary, replace radiator cap tightly.
3. Leave the Steel Seal in your system and drive the vehicle as usual.
NB. If you are introducing Steel Seal via an expansion tank please make sure that there is sufficient room for Steel Seal to go directly into the cooling system and that it does not just sit in expansion tank reservoir.
For best results:
If you have tried inferior products flush your cooling system with clean water after disconnecting bottom radiator hose. Do not use a flushing agent.
