Best value for engine fix

I was looking for a budget-friendly fix for a leaky head gasket. The "Steel Seal Zylinderkopfdichtung-Reparaturflüssigkeit" looked promising. I found a bundle deal for multiple bottles, which was cheaper than buying just one. The total cost was significantly less than what a mechanic quoted me for a repair. Shipping was standard, nothing extraordinary, but it arrived. This saved me a lot of money, making it a worthwhile purchase. I'm happy with the overall value.

Good product, took a while to arrive

I ordered the "Steel Seal 2er Pack" because I wasn't sure one bottle would be enough for my old truck. The ordering process was straightforward on their site. Delivery took 8 days to reach me in Florida, which was a bit slow, but I wasn't in a huge rush. The product itself seems to have done the trick; my coolant levels are stable now. I called their support with a question about application, and they were helpful.

Fixed my head gasket

Used "Steel Seal Zylinderkopfdichtung-Reparaturflüssigkeit" as directed. It worked. My car stopped overheating after about a week. Simple process.

hey, anyone used this stuff on a really old engine? worried it might mess with the cooling system, like clog it up or something.

E evelyn hughes 1 week ago
Nah, used it on a '98 Civic with no issues. Didn't clog anything for me.

I think they say it's safe for all engine types, but if your cooling system is already kinda gunky, maybe run a cleaner first? That's what I did and it worked out.

thinking about grabbing the 3-pack for my truck. any word on how long shipping usually takes to, say, Texas?

N Nathan Reyes 3 weeks ago
Shipping to the US can take a bit, I'd say maybe a week or two? Since they're in Austria.

Yeah, I ordered the single bottle last month, took about 8 business days to get to me in Florida. Might be similar to Texas.
