This is my second use of Steel Seal, the first was in my Mother's car which she sold a year and a half After treated, and All was still Well. 2 Years ago I used it in 1998 Chevy S-10, 4.3 Liter V-6, I have purposely waited 2 years to place my Review on my S-10 so I could report a longer period of usage !I have no idea what is in this Product, but I will tell you that it worked 100% for ME,,,, 2 out of 2 times I used it,, in my Truck it has been 2 years, and NO SIGN of a problem !It is so Rare today that you can trust a product's Claims, But Take MY word,,, THIS STUFF Does EXACTLY What they SAY it DOES,,, THANKS STEEL SEAL !!!! Wish I would have known about you when I had my 1980 6.2 Diesel pickup !!!

Amazing Liquid
Make, Model, Year: Chevy,Venture,2004

I bought a bottle of it back in 2014 for my Chevy Venture that was blowing steam out of the exhaust pipe. i followed the instruction to the tee. It worked just like they said it would. Now 40000 miles later the van is starting to overheat, So i called up tech support and talked to Robert (Very nice & knowledgable person). Then like the Warranty states they will send you out another bottle for free.

Steel Seal Works!
Make, Model, Year: 2004 Chevy Silverado

I used steel seal in my 04 Chevy five years ago. It worked great until a few weeks ago so I requested more. They gladly sent the new elite steel seal. Worked like a charm. Thanks for a great product and great customer service.

It Worked
Make, Model, Year: Subaru Outback 98

In Autumn 2016 I had to keep adding radiator anti-freeze and the car developed overheating problem .....the shop said it was a leaking head gasket and would be 1,800 to fix .....the car ran , started very good , I had put 70,000 mi tires on it , but that price was too high ... then I remembered I had seen Steel Seal recommended on a Youtube video a couple of years ago by a mechanic I highly trust ...... I found this website , called and spoke to Robert .... he was quite nice and knowledgeable ... so I bought it ... I had the shop do the treatment using the simple instructions that came with it ...... Got the car back the next morning , 2 days after Thanksgiving ...... it worked , first try ...... it continues to run good , problem free 2 + months later .... am very happy

Amazed how it worked
Make, Model, Year: 1998 Jeep

I just witnessed Steel Seal being used on a jeep with visible head coolant leak and engine miss. After 30 seconds of putting steel seal into the coolant and starting engine the visible coolant leakage stopped and the engine miss stopped! It was amazing to see it work.

Works Great - Engine runs like new
Make, Model, Year: 1997 Ford Explorer 250K miles

great product. My engine had about 250,000 miles on it when the head gasket started leaking water into the crankcase. We figured that was it for the old gal but my brother recommended steel seal. We followed directions to the letter, and the sealer worked in 10 minutes flat. No more leaks and 4000 miles later, we're at 255,000 miles and she's running like a top. Amazing product. I highly recommend it.
