Ford Fiesta 2006

Used Steel Seal in my 06 Ford Fiesta with a blown head gasket worked a treat, drove like normal for a number of months until I decided to fix the head, highly recommended!

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!

Steel Seal sealed core plug leaks and head gasket side leak. It also stopped a weep from radiator hose! I used 2 bottles what an excellent product I would definitely use again without hesitation

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.

Worked like a charm. I recommend it.

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.

Purchased steel seal from ebay about 3 months ago, since treatment my car has been holding fluids like before the fault. Very impressed with your product, it's saved me a lot of money and extended the life of my car!

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.


Ford Fiesta 2007 1.25 Petrol


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.

This is the second time I’ve use Steel Seal works very well would recommend.

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!

Put entire bottle in expansion tank ran car on a few errands for30mins during this time the engine light came on and my heater started to work I’ve got heat again in my car I filled the bottle up with anti freeze mixture when it had cooled.

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. 


Ford Ranger 2005


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.


Skoda Octavia 2012


Cured our car in no time....Brilliant Product

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.


Corsa sxi+16v. 2007

Worked a treat! No more water leaks. Thank you for a brilliant product.

Just before Christmas 2018 on way to work at 04.45 in the morning my temp gauge went through the roof.i limped the car to work and a mate told me about steel seal.

Brian Cave

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
