Terrible Product

Rating: 1/51

I purchased this product and used exactly as instructions directed. Not only did it not work, I later received a call from the company when I was told by the Chemist that not only would this product ABSOLUTELY NOT WORK WITH ANTI-FREEZE (like instructions say to do) that it would cause it to turn into a GEL INSIDE THE VEHICLE ENGINE. So not only did the product not work they have potentially caused additional damage to my vehicle. He also said he has been trying for months to get the company to change the instructions on the label because the product will not work as directed.

Steel Seal Works I Am Amazed

FAIRVIEW, OREGON -- My truck was running rough at idle steam and water coming out the tailpipe water in oil and exhaust smell in rad and high pressure in cooling system. I ordered steel seal, followed the directions, pulled the thermostat and put the product in. Started the engine and in ten minutes no steam or rough idle. Took for a half hour drive at hwy speed and let cool for an hour and did the same drive again.

Ended leaving in the engine for two weeks before putting the thermostat back in and flushing and filling with the antifreeze. They said to use truck is running great engine light off. That is telling me that no water or anti freeze passing the oxy sensor in the exhaust, no water loss at all. The stuff works. Tried other stuff no luck. If you think you have a crack or head gasket problem give it a try. What you got to lose?

FALL RIVER, MASSACHUSETTS -- STUFF WORKS. I was noticing white smoke and my tachometer was fluctuating when I would start my 2003 Chevy Monte Carlo back in 2013. Went to see my mechanic and he told me a head gasket to do it right it's gonna cost about $1200. Bought Steel Seal, cleaned my radiator and changed my oil. Followed the directions on 11/05/2013 with 83,000 miles and til today 08/03/2016 with 99,512 miles still running good. Thank you STEEL SEAL.

I used Steel Seal in my Stag engine. It stopped the leak, blow the head gaskets and blocked all of the waterways in both the block and the heads. When I called Steel Seal, they said would send a refund but they never did.

It Works!

WHITTIER, CALIFORNIA -- So my 1994 Jeep Cherokee Sport was not leaking any coolant nor was it getting into my oil however the #6 cylinder was leaking exhaust gases into the coolant causing the head to run hot and the upper hose to be hard due to the exhaust pressure being pumped into the system. I researched the Steel Seal as much as I could online. I bought the product and called the tech line to go over what I needed to do before I started for my situation. I drained and flushed the extended life coolant from the system and from the overflow tank. Although it did not say to I also removed the thermostat like Scotty ** did on his youtube video.

I then removed the #6 spark plug and injector wire. I added the two bottles of Steel Seal for my 6 cylinder motor, $100.00 worth of product. I then added distilled water to top off the system. Next I replaced the rad cap and ran the car at idle in my driveway at 1000 rpm twice for one hour on and one hour off to let it cool down. I then ran the car again at idle twice for 1/2 hour on and let it cool for 1 hour off. The next morning I reinstalled the plug and injector and I drove it to Costco to get gas not hard just like an old guy.

Because It had no thermostat it stayed around 150% which was great because before the treatment it would get up to 230% quick forcing me to shut her off just before the red line. The next day I re-installed the new 195% thermostat from Napa which is what the factory temp for my motor calls for and the temp gauge went close to the red 230% so I pulled that thermostat out and put a 180% thermostat which is now keeping me in the 205-215% temp safe zone. Seems I had 2 issues one being a defective new thermostat and the other the head gasket.

In a few days I am going to flush out the Steel Seal because I do not want it to clog up my system later by accidentally adding the extended life coolant which is not compatible. Dex cool is not compatible either according to the directions that came with the product. Today I am still concerned and a bit skeptical of what the long term outcome will be.

Steel Seal Head Gasket Repair Product

PHILADELPHIA, PENNSYLVANIA -- Something was wrong with my car and I found out by asking a friend of mine who is a mechanic that I had a blown head gasket. I know such a problem like this should be figured out in an instant, but I am not a car guy. In fact, I know absolutely nothing about cars other than they have four wheels! Anyway, my friend who is a mechanic recommended Steel Seal. Of course I decided to give it a try because the sealant would be a lot cheaper than having the entire thing replaced.

At first I was hesitant about trying the product by after speaking with a company representative, I was more optimistic about my experience. Plus, the man even said he would give me a full refund if the product didn't work. With that promise in mind, I had my friend apply the sealant. I am happy to say the product fixed the head gasket and my car runs perfectly fine. I called the company back to tell them about my experience.

PHOENIX, ARIZONA -- I love this stuff! I can honestly say even though it's a total band-aid, it saved me thousands of dollars. I have a 1997 Camry and it's held up for almost 4 months now. If it does not work for you, then you don't know how to follow directions. User error is not Steel Seal's fault.

Ruined My Heater Core

Used it on my 2004 BMW which was pushing white steam out of my exhaust. In about 2 hours my heater stopped working and my heater core started leaking into my floor on the passenger-side!!! It cost me over 950 bucks to have the heater replaced! This product is very bad. When I called I had to leave a message, them they never called me back.

Don't Use Steel Seal
By -

I recently bought a 2003 Nissan Sentra GXE with the 1.8 engine for my daughter. The car has 109K miles, but is in perfect shape. After a few months I noticed that the car was using about 1 quart a week of antifreeze. I could not find any leaks, but after a while it began to blow white smoke out of the exhaust and I could smell antifreeze coming off the exhaust when it started up. Clearly I had either a blown head gasket or a cracked head. I called my mechanic it would be 14 hours labor (~$1000) to replace the head gasket + parts ($100-$200).

He told me the much better choice would be to do an used engine swap, since the labor to do that was actually a little less at 13 hours. He found one from a crash test car that had 216 miles for $1300, which would bring the swap to around $2500 with misc. parts. He said it would be a really bad idea to do head gasket, since most of the time he has seen other damage to the piston rings. For $1300 more, to go to a nearly brand new engine was clearly the way I intended to go. I did some research on Steel Seal. I was very skeptical, and was concerned it might cause other damage, but I thought I'd give it a try since I intended to swap out the engine if it did not work anyway.

I followed the instructions exactly, left it to cool down overnight. When I drove the car the next day, it appeared to do absolutely nothing to fix the car. The white smoke was not that bad, so I thought I'd drive it a few days and see.
On the 2nd time I drove the car all of the sudden when all the way up on the temperature gauge and the car started running badly. This rise in the temp. had never happened before.

I drove it a few and parked the car. After the car cooled down, I pulled the radiator cap. To my amazement, the radiator was completely plugged with a hard white polymer (note when I added the Steel Seal it was clean metal). Bottom line, now I need a new radiator too. DO NOT put this product in your car, you will be very sorry.
