Steel Seal TV Ad


Jeep Cherokee 3.7


I have used this stuff 3 times,on different cars,and I can honestly say it works just as it states. My current Jeep has been running for over 10,000 miles without any problems and before adding Steel Seal it blew the coolant out of the header tank within 15 minutes of starting.I can honestly say I have never topped the coolant up since adding it 10 months ago.I can only say how it has worked for me and I can only assume that if the instructions are followed to the letter,then it will work.I would not hesitate to use it again.

My works car started showing symptoms of head gasket failure so I used steel seal just to keep the car going for a few weeks but all symptoms have gone since using.

Steel Seal saved me from replacing the cylinder head gasket! The vehicle originally came in with the core plugs in the head corroded away, leaking coolant causing the spark plug to seize in and snap.

Own a vauxhall frontera 2.5 tds and after every drive out i had to keep checking the coolant levels as they dropped quite rapidly..would say i had to top up every 2-3 days.

Have to say that the product did what it said it would. I had had a mysterious leak for months and this rectified it first time.

Having been loosing water for a few weeks, I thought I'd try Steel Seal. And have to say it's been nine weeks now and no problems. I would definitely recommend this product

I used this to resolve a headgasket issue, it seems as though it has now stopped smoking from tail pipe, also coolant loss now seems good. Oil leak was very minor seems to have cured faults.

What a brilliant product went from thinking it wouldn’t ever work that the problem was too far gone chuck the hole bottle in 40 - 50 minutes (for me) the problem was fixed as if by magic will be recommending to everyone!

Thought this was the end of the line for the faithful work horse. A week after passing her mot without issue she suddenly springs a leak and leaves a significant puddle on garage floor. A friend suggested steel seal which I bought and tried straight away. Worth every penny as old faithful is now back on the road and trouble free again.

Truck sat at garage for two weeks as they had no time to fix the blown gasket. Asked them to put in a sealant and they chose steel seal. Had to travel just over 180 miles as we had moved house. All I can say is thank you, rock solid. There was a slight temp fluctuation and smoke for about 250 yards then steady as a rock, no water loss, filter and pile was changed and no milky oil. Got me home with no problems at all. I am so grateful. Saved ££££’s

I was losing 1/3 litre of water every 300 miles. Mercedes and other garages said your head gasket had a crack and was quoted 3k to fix it. Car has 125000 on the clock and worth around 6k in current condition. Friend mentioned Steel Seal so bought a bottle online for £27 followed the instructions and 1.5k miles later the coolant warning light has not reappeared! Replaced the plugs which had been damaged by the water leakage and boom good as new. Brilliant product!

I just followed what it says on the bottle and changed my engine oil after to to make sure every think was good and it's been 6 months now as no overheating and it hasn't lost any coolant I also went to London and back from Wolverhampton with no issues.


Ford, Fiesta, 2006


Does what it says on the tin. Very good product!.

We had a customer in with a Corsa with a coolant loss and loss of power, was no sign of coolent leaking from the engine hoses radiator removed spark plugs number two plug was a odd colour so we proceeded to do a compression test number 2 cylinder was down by around 55-60 and to also add we was getting pressurisation in the cooling system a typical blown head gasket symptom price the job up accordingly for the repair when he received the price he nearly hit the floor he asked is there any other alternatives so we suggested Steel seal which we had heard good reports about but never actually used before. Followed the instructions and to my amazement it actually worked cylinder to compression had risen we kept the car for 2 days drove it around when possible and no coolant loss engine performance had restoredone happy customer. 5 star product

I was recommended this product by a friend as I’ve got an older car so I wanted to save money. What a genius! I’ve saved hundreds using Steel Seal!! I am singing your praises! Thanks so much, excellent product!

Used Steel Seal, in the vehicle and followed instructions called Steel Seal Customer Service for extra support and advice, very helpful staff, gave me some extra tips for my particular vehicle. Worth calling staffing if unsure, staff are well trained in advising for particular vehicles.


Saab 9-3 Linear

Best car I ever drove, then the coolant started draining and I couldn’t find the leak, had a few weeks of constantly draining fluids to the point I was scared to drive the car any distance. Finally I found a decent mechanic.. two options 1/ a £450 nil to strip back and repair leak or 2/ try Steel Seal . So I bought Steal Seal and eyes watered at the price ... best £40 I’ve spent...ever. It just works, amazing stuff. I had never heard of Steel Seal until I bought it and used it on my Saab . She’s an old car now and probably not worth the £450 repair bill I’d have if Steal Seal didn’t work.

Worked like a charm. I recommend it.

Started loosing about a header tank of coolant over a week. Found coolant around bottom of timing belt cover and thought it was coming from the water pump. Removed the covers etc and found coolant was coming from the back corner of the cylinder head.
