Make sure the engine is cold and the coolant is clean.
Remove the radiator cap, pour in the recommended amount of Steel Seal®, and tighten the cap securely.
Tip: If there is no radiator cap, pour Steel Seal® directly into the expansion tank*.
Turn on the heater & fan to the highest setting. Start the engine and run it until it reaches full operating temperature & for an additional 30 minutes let it idle. Turn off the engine and allow it to cool down for at least 6 hours.
WARNING: Während der Anwendung regelmäßig die Temperaturanzeige beobachten. Wenn der Motor zu heiß wird, sofort Motor abstellen, abkühlen lassen und erst danach fortfahren.
Top up with coolant if necessary. Leave Steel Seal® in the system & drive the vehicle as usual.
| ENGINE SIZE (CC) | BOTTLES | |
|---|---|---|
| 1. | up to 2.4 liters (2,400cc) | 1 |
| 2. | 2.4 to 4.0 liters | 2 |
| 3. | over 4.0 liters (4,000cc) | 3 |
*Note: Before introducing Steel Seal® via the expansion tank, make sure to empty it so that Steel Seal® can enter the cooling circuit. Then continue with step -2-.
3 tips for best results!
A blown head gasket is usually the result of repeated overheating. The cause should be rectified before using Steel Seal®.
Important note: Steel Seal® is is not compatible with all coolants!
Steel Seal® is not compatible with silicate-containing "long-term"/"long-life" coolants (e.g. G12evo, Glysantin G65, Eurolub D-30 D-40 D-48 D-65)
Recommended: Use Steel Seal® with pure water or silicate-free coolant (max. 25% antifreeze), or a min. 3:1 water-antifreeze mixture.
In case of contamination or previous use of additives in the cooling system rinse with water several times in advance. If used with pure water: Steel Seal® can be drained and the system refilled with any approved coolant after the application.
Additional instructions in case of backpressure
Bei zu hohem Druck im Kühlsystem – aufgrund von Verbrennungsgasen aus dem Motor – können folgende Anzeichen auftreten:
• Kühlwasserschläuche fühlen sich hart oder aufgebläht an
• Deutlicher Druck beim Öffnen des Ausgleichsbehälters
• Bläschen im Kühlwasser, während der Motor läuft
Methode 1 – bei sehr hohem Druck im Kühlsystem
Zylinder mit Überdruck finden:
Entferne nacheinander jeweils eine Zündkerze und starte kurz den Motor.
Achte dabei auf die Blasenbildung im Kühlwasser: Stoppt sie, ist der betroffene Zylinder gefunden.
A.) Cylinder found?
Beginne mit Schritt 1 der Anwendung, während die Zündkerze und – wenn möglich – auch die Einspritzleitung entfernt bleiben. So gelangt kein unverbrannter Kraftstoff in den Brennraum.
After the application Zündkerze und Einspritzleitung wieder einsetzen!
B.) Kein eindeutiger Zylinder gefunden oder mehrere betroffen?
Oder dein Fahrzeug hat eine Common-Rail-Einspritzung?
Dann verwende Methode 2.
Methode 2 – bei leicht erhöhtem Druck im Kühlsystem
Wenn der Motor kalt ist, den Ausgleichsbehälter so weit entleeren, bis das Kühlwasser gerade noch sichtbar ist. Dann Fill in Steel Seal® and the Verschluss offen lassen, damit sich kein Druck aufbaut.
Falls möglich, direkt in den Kühler geben und auch hier den Kühlerdeckel offen lassen
Bonus tips after use:
After complete cool down, drive the vehicle for 30-40 minutes with low rev. Then allow the engine to cool down again - Steel Seal® can continue to work. It remains in the system for 2-3 drives and can then be drained, but does not have to be. After that, any approved coolant can be used. In the case of undiluted or highly concentrated Longlife coolant, remove Steel Seal® beforehand.
Tip: Check coolant levels after the first 100 km for any hint of further loss of coolant.
Guarantee! If symptoms persist after 1 week of daily use (e.g. loss of cooling water), please contact us! We will check whether a second application makes sense - until you are satisfied.
Instructions for flushing the cooling system
Other additives or impurities in the coolant? Flush cooling system with fresh water - without detergent!
Flush & bleed cooling system
Flush the cooling system:
- Park the vehicle safely, engine cold, ignition off, apply the handbrake.
- Remove the lower radiator hose and drain the coolant completely (dispose of in an environmentally friendly manner!).
- Insert the water hose into the radiator or expansion tank opening and rinse for a few minutes at low pressure (no high water pressure!).
- Reattach the radiator hose & fill the cooling system with fresh coolant.
Venting:
- Loosen bleed screw(s), fill in coolant until liquid escapes, then close screw(s).
- Leave the radiator/expansion tank open, turn heating to the highest setting and the fan to the lowest level.
- Start the engine & rev it briefly to 3,000-4,000 rpm several times.
- Switch off the engine & close the radiator/expansion tank cap.
Concentrated cooler rinse from PowerMaxed 325ml
If there are traces of engine oil, sludge or corrosion residues (brown-reddish) in the cooling system, for example because you have been driving with only water in the cooling system for a while, we recommend thoroughly cleaning the cooling system before use, e.g. with the Concentrated radiator flush 325ml from PowerMaxed.
