Backpressure in the cooling system
VW Sharan, 1.9 TDI 96 kW (130PS), year of construction: 2007
Peter had noticed severe overpressure in the cooling system of his VW Sharan and was losing approx. 1 liter of coolant per 100 km.
1 bottle of Steel Seal filled into the cooling system according to the instructions for use.
Pressure in the cooling system normalized immediately after application and the loss of coolant was stopped.
After more than 4 years, Peter is still driving with the original engine of his VW Sharan and without dismantling. Steel Seal has permanently repaired the damage to his cylinder-head gasket.
BMW 3 Series E46, year of construction: 2005
During a routine check, Fritz noticed oil in the coolant tank and shortly afterwards compression pressure in the cooling system of his BMW E46.
After rinsing the cooling system with clear water, 1 bottle of Steel Seal was filled with fresh, pure cooling water in accordance with the instructions.
Immediately after the application, both the high compression pressure and the oil disappeared from the cooling system.
Long-term experience
The cooling system has been clean for 18 months and the BMW E46 is back on the road without any new symptoms. Without dismantling or replacing engine parts.

Exhaust gases in the cooling system and loss of cooling water
SEAT Ibiza, 1.2 Petrol 51kW (69PS), year of construction 2011
Richie had noticed a loss of cooling water in his Seat Ibiza. After replacing the water pump and thermostat, the loss of water persisted. A CO2 exhaust gas test in the cooling system was then positive, i.e. exhaust gases (CO2) were detected.
1 bottle of Steel Seal filled into the cooling system according to the instructions for use.
Positive. Another CO2 test remained negative. No more exhaust gases were detected in the cooling system after the application of Steel Seal. The loss of coolant was also stopped.
After 8 months and approx. 25,000 kilometers driven, there is still no cooling water loss.
