Water in the oil and in the combustion chamber [Ford Galaxy WGR 2.3, 2001]
| Wieder Erwarten gut. Habe den Kühler gespült und entkalkt, dann noch 2 mal gespült und danach Steel Seal in den unteren Kühlerschlauch und den Rest dann mit Destiliertem Wasser oben über den Ausgleichsbehälter eingefüllt. Wie beschrieben den Motor auf Betriebstemperatur gebracht und noch eine halbe Stunde weiter laufen lassen. Am nächsten Tag dann gefahren und alle ist in Ordnung :) Günter Starauschek 14.04.2023, 63897 Miltenberg |
Coolant leaking from engine block [VW Golf 5, 2004]
| I had cooling water leaking from the engine block on my last Golf and it worked again. I've ordered from Steel Seal before and have only ever had good experiences. The staff are very helpful and help with the whole procedure. If something should go wrong, you always have the guarantee and get a free replacement bottle or your money back. I am very positively surprised and will always order from the store again and can only recommend it to everyone! Niklas Huck 24.02.2023, 49074 Osnabrück |

Cooling water is lost - negative pressure [Chevrolet Rezzo 2008]
| I bought Steel Seal because our car was leaking cooling water and there was also negative pressure. About half a liter of water per day. Did everything according to the instructions. Even flushed the cooling circuit with 30 liters of water. Then filled a bottle of Steel Seal into the expansion tank with fresh water and let it run for 30 minutes after reaching operating temperature. Leave to cool overnight. The next morning, no water loss and no more vacuum. The engine runs smoothly again. Can really only recommend Steel Seal. Thanks for the super product! Torsten Franke 27.01.2023, 17367 Eggesin |
Oil in expansion tank [BMW 320i BJ:2006]
For 3 years I have been driving my BMW with one liter of oil per 400 km. Shortly before Christmas last year, I only managed 200 km overnight. After opening the expansion tank, I saw the malleur: oil in the coolant. Then I came across Steel Seal. I thought it was worth a try. And lo and behold, it helped 100 percent. No more oil in the expansion tank and I can get back to my 400 km. I can only recommend this product with a clear conscience. Simply great!

CHP Ecopower 4.7 with loss of coolant
My message about the application: CHP Ecopower 4.7
Situation: Water cooler for the catalytic converter leaking. 1 liter coolant loss/day expansion tank had to remain open!!!
Application: Steel seal in the expansion tank (coolant was clean) and filled up with distilled water Expansion tank closed, system ramped up to 95°C (no more emergency shutdown possible). System cooled down to 30°C with the expansion tank closed
Result: Approx. 0.3 liters have disappeared! >System tight. System has been running for 3 days (expansion tank open > safety measure) > No loss! > Great. The CHP runs 23.5 hours a day.
I am very satisfied, thank you
