Customer Reviews
Mostly good experience
I purchased the Steel Seal für PKW to address a small head gasket issue. The product itself seems to have worked; the white smoke from the exhaust has stopped, and the coolant level is stable. Delivery was reasonably fast, took 5 days to reach Denver. My only minor point is that the application instructions could be a little clearer on what to do if you have an older car with a very dirty cooling system, even though I did use the Kühlsystem-Reiniger first. Overall, a good value for the repair.
Solid value purchase
I was looking for a cost-effective solution for my motorcycle's weeping head gasket and found Steel Seal für Motorräder. The price point was much better than a full mechanical repair. I managed to use a small discount code I found, which made it even more appealing. The shipping was free, which is always a plus. For what I paid, it felt like a smart investment. The repair seems to be holding up well, so I'm happy with the overall value.
Fixed my old truck
I bought the Steel Seal 473ml Flasche for my old pickup that was leaking a bit of coolant. I was a bit skeptical at first, but hey, it actually worked! The instructions were easy enough to follow and I didn't need any special tools. Shipping took about 4 days to get to my place in Ohio. The leak stopped and the engine seems to be running fine now. Saved me a ton of money not having to take it to a mechanic for a head gasket job. Pretty happy with it.
Reliable as always
This isn't my first time buying from Steel Seal. I've used their Dichtungsmittel für Motorblock on two different vehicles over the years. This time, I needed the Kühlerdichtmittel for my daily driver. Just like before, the product arrived quickly, and it did exactly what it claimed to do. It's consistently reliable, which is why I keep coming back instead of trying other brands like Bar's Leaks. Good to know I can count on them.

Hey, thinking about getting Steel Seal for a small leak. Does it really work for all engine types or are there some it's not good for?
Is there usually a discount code floating around? Looking to buy a couple bottles and hoping to save a bit.
