Steel Seal is a simple do-it-yourself product for sealing cylinder head gaskets. Steel Seal is a sealant that becomes as strong as steel and seals permanently. Steel Seal can be used in all types of cars and engines that have a water-borne cooling system, regardless of whether it is petrol or diesel, and does not clog the cooling system. Steel Seal will seal all types of broken cylinder head gaskets, cracked engine blocks, loose cylinder liners and skewed cylinder heads.
Compatible with all types of traditional coolant. Steel Seal has not been confirmed to be compatible with waterless coolants or pure coolant as water must be present in the cooling system.
1 bottle: Engines up to 2.0 liters displacement
2 bottles: Between 2.0-4.0 liters stroke volume
3 bottles: Engines over 4.0 liters displacement
Step by step instructions
SEAL FOR LEAKING HEADGASKET IN THREE SIMPLE STEPS:
For best possible result:
If you have tried other substandard products, rinse your cooling system with plain water after removing the lower radiator hose to the radiator. Do not use radiator cleaners.
After rinsing the cooling system, reconnect the lower radiator hose to the radiator.
FURTHER STEEL SEAL INSTRUCTIONS:
These instructions are for those who have overpressure in the cooling system, which usually shows up as bubbles in the expansion vessel or air puffs out of the radiator cap.
Find which cylinder is causing the overpressure in the expansion vessel or the back pressure. (Remove one spark plug at a time until it stops bubbling)
Before starting the engine, remove the spark plug or fuel injection from the cylinder that caused the bubbles in the expansion vessel or overpressure. If you can access it, also remove the fuel injection cord from that cylinder to limit the amount of unburned fuel.
– If you do not find the spark plug that causes the bubbles, run the engine with the coolant so that it covers the top of the heat sinks in the radiator with the radiator cap off. or leave the lid of the expansion vessel off and hold in only so much water that you can just see it.
– Be sure to let the engine run until it warms up with the spark plug / fuel injection removed and let the engine run one last time with the spark plug / fuel injection retrofitted.

LIGHT WASTER LOSS AND HEATING
FREELANDER V6 2002
“My car mechanic vented the cooling system as I had sporadic problems with the temperature gauge that began to live its own life. Leaked about a pint of water a day. He performed a test that showed that I had a small leak in the cylinder head gasket. I had previously tested other products that seal cylinder head gaskets that did not work at all. My mechanic recommended that I try Steel Seal as he only heard about one case when it did not work. I bought and poured in and now it has been two weeks without water leakage or overheating problems. I’m so thankful!”
COOLANT DISAPPEARS, WEIRD LEAK
VOLVO 940, 1998

COOLANT LEAKING AT HEAVY ACCELERATION
RANGE ROVER SPORT 4.2 SUPERCHARGED

MISFIRE AND WATER IN THE EXHAUST
HONDA CIVIC 2003
“The coolant level dropped quickly, the car overheated, did a pressure test, broken cylinder head gasket. Fantastic product, it does what it says according to the bottle.”
BROKEN HEADGASKET – WATER IN THE CYLINDERS
OPEL FRONTERA B 2.2 1999
“My car went like a steam locomotive with water vapor from the exhaust pipe and misfires. Did as it said on the bottle and it seems to have done as it should. Checked the fluid level and it has not moved at all, the car runs as it did before the cylinder head gasket broke. I’m very happy with the Steel Seal.”
CRACK IN ENGINE BLOCK (ICE DAMAGE)
MASSEY FERGUSON 1947 TRACTOR
“Engine block in cast iron as leaked coolant into 3-4 Stables. Have never used Steel Seal before but after 30 minutes it stopped leaking coolant. The engine ran for another 30 minutes and there are still no leaks, I am very impressed. Will buy me another bottle and use again.”
David Parry ( Dave’s Auto’s )
OVERHEATING, OIL IN COOLANT
MITSUBISHI L200 2.5TD 2003
This is the first time I use Steel Seal and I am so happy with the result, just as it said on the bottle, it has fixed the problem with my cylinder head gasket. I highly recommend this product to everyone as it is not only very effective but has also saved me several thousand kroner. An excellent product. Paul
FORD ESCORT 1.6
“I thought it was the end of my faithful Escort when the cylinder head gasket started leaking. Now it is almost new. Just follow the instructions… it works !!!”
MAYONNAISE IN THE EXPANSION TANK
ROVER 214SI 1997
“This product is incredible, simply amazing. I have never believed in “floating repairs” like this. After 100 km, the pressure test shows ok and there is no more oil in the water tank. My Rover 214 is saved! I will always be grateful.”
WHITE SMOKE COMING FROM THE EXHAUST
VW GOLF MK2 1991
“When I first saw this product, I thought that it can never work. But after three weeks, everything is still fine. Would recommend it to everyone as it is well worth testing if you think you have a broken cylinder head gasket.”
“Even though it was just a small leak, it was still worrying. I contacted the car workshop that usually services the car and after a quick look, they came to the conclusion that it might be the cylinder head gasket that was about to go with it and that it would cost between 5000 and 7000 kronor to repair. I therefore bought a bottle of Steel Seal because I had nothing to lose. I was careful to follow the instructions and the result came immediately and was perfect. I just saved SEK 5,500. I would not hesitate to recommend this product to anyone who is considering trying it.”
ISUZU TROOPER 3.0 D 2001
“I noticed that there were water deposits on two of the spark plugs when I replaced them. Which confirmed my suspicions as I have regularly filled coolant. After two bottles of Steel Seal, the problem is now solved and a potential nightmare has now been avoided. Thanks!”
CHOCOLATEOIL IN CYLINDER HEAD
“Stunning – wonderful – amazing. I was so unhappy that I had saved so much for a trip and a Nintendo Wii for my five year old, when I was told that it would cost 10,000 of more than one workshop to fix the problem when I was recommended to try Steel Seal. Really thank you very much, it worked better than expected. We will tell more about your product when we are on the trip.”
LEAKAGE FROM THE SIDE OF THE CYLINDER HEAD

CONSTANT DESCENDING WATERLEVELS IN EXPANSIONTANK
2004 MG TF 135
“I was really hesitant about something that comes in a bottle and promises to fix the problem.! But I got proof that I was wrong. Thanks for following the instructions. And my MG has stopped drinking so much water and the performance is like when the car was new. So I’m really impressed. Had not noticed that the car had lost power until I poured in Steel Seal. It is an incredible product that works!”
OVERHEATING AND CONSUMING COOLANT
FORD FIESTA 1.25
“Fantastic product. Just follow the instructions on the bottle. We have used this product a few times in our car workshop for our customers who cannot afford to repair the cylinder head gasket. Of all the cars we have tested it on, only one did not work and that was because the damage to the engine block was too great and even then the people at Steel Seal were wonderful on the phone.”
WATER IN OIL
OPEL CORSA 1.2 16V
“Steel Seal uses a student’s Opel Corsa with a broken cylinder head gasket. He simply could not afford to replace the cylinder head gasket. Steel Seal worked perfectly. I recommend it to everyone before you change the cylinder head gasket.”
Chainbridge mot centre
AUDI A3 2006
“Our car had been drinking water for a year, a new radiator, a new water pump and still needed to be refilled. Used Steel Seal and now it is fixed, no problems and it no longer drinks water.”
WHITE LIQUID ON THE OILCAP
1999 MERCEDES E280 W210
“Had problems with white mud that accumulated on the oil cap but nothing on the stick. Tried a few other products to see if there really were problems with the cylinder head gasket but none of these products seemed to work. As a last resort I tested Steel Seal and pulled backwards, within a few minutes the deposits on the oil cap had disappeared so it worked for me and I only needed to use one bottle even though two were recommended. I followed the instructions to the letter and it seems to have worked. The engine runs smoother under load and idling has improved. For my part, I would like to recommend the product to anyone who has a problem with leaking coolant. It does exactly what it claims on the bottle and it works. Thank you so much to everyone at Steel Seal who has saved me several thousand dollars in workshop costs.”
SAVED OVER 600€
ROVER 216 CABRIOLET 1996
“I was skeptical at first but after receiving a cost estimate of 3500 to repair the cylinder head gasket together with the money back guarantee, I gave it a try. The result – no more overheated engine, fault or water vapor from the exhaust pipe. Well done and easy to use. Many thanks!”
UNEVEN DRIVING, CONSUMING COOLANT
PEUGEOT 206 1.4 1998
“This is the second car I have used Steel Seal on. The other was a 1.8 Freelander 18 months ago and it is running at full capacity. It has worked on both cars and saved me several thousand dollars. Easy to use. Literally just pouring in and letting the engine run. There is no other product I have ever used that has given the results it has promised. really keep what they promise. Do not listen to the critics who say that there is no shortcut to fixing a broken cylinder head gasket. Because there is!”
BAD PERFORMANCE, CONSUMING WATER
2001 PEUGEOT 406
“Watched the video and also the youtube video regarding the 406. Drained the cooling system, flushed the engine and refilled. Followed the instructions and hear and be amazed, after an hour it was ready. Two days later I tested on the camper without any problems. I have to save a few thousand. Thanks Steel Seal.”
CONSUMING LARGER SCALES OF COOLANT, OIL IN THE WATER
FORD MONDEO 1998 1.8L PETROL
“Recommended by the workshop, Felton Wigan Road Euxton. The Steel Seal was poured in and the car idled for an hour. The problem is solved and has not had to refill coolant for over two months. I am very pleased as the option to tear down the top would not have been financially defensible.”
CRACK IN ENGINE BLOCK
RELIANT ROBIN (TRIKE) 1986
“After building an engine from two, I was devastated when I saw that the engine block was cracked. A guy at Jamar engine factory suggested Steel Seal. I was very skeptical and tried mild meringues !!! I will share on all trike forums and facebook pages !!! Fantastic product! Thank you so much Steel Seal !!!”
LEAKING COOLANT BEHIND MANIFOLD
MG ZR 1.4 2004
“I was going to give it a try before I tore down the engine as it sprayed coolant straight out behind the manifold and I had to refill every day. Take off my hat for Steel Seal, which is a wonderful product as it fixed the problem after an hour and a bottle. Thanks Steel Seal.”
