Steel Seal needs to be introduced to the vehicles cooling system for best results,
- If you have tried inferior products or run an antifreeze other than an ethylene glycol flush your cooling system with water after disconnecting bottom radiator hose. Do not use a flushing agent.
- If you have flushed system reconnect bottom radiator hose.
- Engine must be cold, turn the heater to maximum but not the fan.
- Using factory recommended antifreeze (ethylene glycol), pre- mix one Litre of water and one litre of antifreeze with recommended amount of Steel Seal. Do not use with any other antifreeze! Before starting the engine, pour the pre-mixed solution into the radiator or header/overflow tank first, then top up the radiator/cooling system if is not yet full with an additional mixture of 50% water and 50% antifreeze.
- Tighten the radiator cap back on.
- Start the engine. Holding the Revs at around 1,000RPM. Continue this process until the temperature has reached 210f/99c degrees (This is normal operating temperature, just wait until the fan has kicked in) then stop the engine and allow it to cool for one hour. After the engine is cool, start it again and be certain that the temperature reaches 210f/99c degrees again and then allow it to call once again. Repeat this step one more time within the same day. After the thermostat has opened release all air within the system and top up the radiator with more coolant if required, replace radiator cap on tight let the engine cool completely.
- Now you can drive vehicle as usual.
To carry out the above sounds more complicated than it is. It is a relatively simple activity.
Additional Directions
These directions are for people that have a lot of pressure building in the cooling system, usually shown as bubbling in the header tank or air forcing past the coolant cap.
- Locate the cylinder causing the bubbling in the overflow tank or backpressure. (Remove plugs one at a time till bubbling stops)
- Follow the directions above up to and including No.5.
- Before starting the engine, remove the spark plug or injector from the cylinder that was causing the bubbling in the overflow tank or backpressure. If accessible, remove injector wire from that cylinder. This will limit the amount of unburned fuel going into the combustion chamber.
- If you can not find the spark plug that is missing, run the engine with the coolant level down to the top of the radiator core and with the radiator cap off.
- Continue with direction No.6 above. Make sure to run the engine two times up to temperature with the spark plug /Injector out and for the one final time with the spark plug/injector back in place.
