Ford Mondeo 1.6 petrol Turbo 2012

After having head gasket replaced twice engine still loosing water with no visible leaks (approx 3/4 gallon a day). After 3 months of problem after problem and at my wits end saw a few adds about Steel Seal read the reviews and thought I would give it a go. Hey got nothing to loose. Followed instructions to the letter apart from the video states 60 mins & bottle says 30 mins so I went 45 mins.
Now no steam, starting on the button and no water loss in the last 1,000 miles.
At £4099.00 +vat and fitting for a new Ford replacement the price of Steel Seal is a no brainer.

I purchased the Steal Seal from Euro car parts Bristol and used as per instuctions on the bottle and it has worked perfectly. Many thanks a great money saver. 100% happy.

What a wonderful product. It does the job brilliantly. My car was overheating and the garage wanted hundreds to change its 2 cylinder head gaskets (its a V4).
One dose of Steel Seal and the symptoms disappeared altogether. Also the car runs better with more power available I would recommend this product to anyone with similar problems.

I've used this before in a run about of a BMW.

This time it was for the GF's dads car. I said we'd give it a blast, bought it in Halfords which was handy, fired it in and went for a few spins down the road.

It solved the head gasket and even managed to seal the warped head on it.. now she starts on the button, doesn't spit it's coolant everywhere now. Gonna pick up another bottle I think and put it in my own car.

Ford Mondeo 2.2 TDCI. 2004

Was looking at 8 to 10 hours work to fix the head gasket. Tried other so called head gasket repair solutions without success. Tried Steel Seal as a last resort, not really expecting it to work. Followed instructions exactly, then went for a 30 mile drive. No loss of coolant and no sign of combustion gas when doing a sniff test.

Very very hesitant to use steel seal, when something sounds to good to be true it normally is. However not with steel seal, followed the simple instructions and my problems are no more.. Highly recommended product great work guys and girls.

Was hesitant to use initially but very glad I did, the product worked amazingly well I would highly recommend.

Was not to sure about trying this as i hate quick fixes, but to my surprise within a hour it was fixed! Hot air blowing starts easier and holds water now. Really impressed.

Daniel Smith

Honda Civic 2002 1.6 SE

I was really hesitant to try this, but I did and it worked a treat! I couldn't be happier with the way this product worked! Followed the instructions exactly as on the back, and within an hour the car was almost smoke free - now - 3 weeks later its still smoke free.

Your product was suggested to me by a friend as a possible fix for my van. I,ll be honest I wasn't holding out much hope. A 1000miles later and still going strong I,m happy to say I would recommend your amazing product to anyone with a similar problem :)

1998 BMW 318i (E36)

Car had overheated a couple of times - due to a coolant leak- and had started to build up a lot of back-pressure in the cooling system. Eventually the car started to misfire and white smoke from the exhaust confirmed the inevitable. I was going to scrap the car - apart from the head-gasket blow a lovely car, but not worth much -, but decided to give this Steel Seal a go. Follow the instructions and it works! The car stopped misfiring within 10 minutes of adding product and after 45 minutes was blowing clearer smoke. Left it overnight, it now runs perfect! Excellent product, but, follow the instructions and, check your coolant water level before adding.

Vehicle came in to my garage with several faults, loss of oil and coolant so carried out a head gasket test found it had early signs of head gasket failure. advised customer that he needs a new head gasket/head skimming etc but he didn't have the funds to pay for the job so I said give steel seal a go to see if it helps you out for a while. we followed the



Followed instructions on the bottle.
Went for a drive no more steam coming out of the exhaust.

Ii have also used this on a Astra head gasket gone water into oil. did the same followed the instructions. this was 5 years ago and the car still runs fine.


Opel Zafira 1.6 2000

Just bought Steel Seal this morng, but before that I was in doubt this might be just a scam, but knowing it was sold in Halfords i decided to give it a try, my problem was a heavy white smoke in my car even it was already warmed up, and a few traces of oil in the engine,


Ford Cougar 2001

My old V6 had blown its head gasket between a cylinder and the water jacket. Pressurised water system and needing a top up every 50 miles. Cost of fitting a new head gasket is about what the cars worth.


535I BMW 2000

My friend who is a mechanic told me that the head gasket had gone. He suggested steel seal as had used it on a car years ago and said it is still driving around now. Purchased 2 bottles, followed instructions and now is fixed, thank you to the clever people at Steal Seal.

I had heard about Steel Seal and as I was facing a £1600 bill to replace the head gasket I thought I'd give it a go. Flushed water coolant and replaced with Antifreeze and added Steel Seal. Worked like a dream! No problem now and no signs of oil to water contamination. Worth every penny!

Iain Nixon

Renault Clio 2003

Girlfriend's car was getting old but always a reliable runabout. Discovered signs of water mixing with the oil inside the valve cover and filler cap.....aswell as a small coolant leak around the water pump housing. We thought it was time to start looking for a replacement car. My dad suggested trying a bottle of Steel Seal before we gave up on the car completely. Dad has used SteelSeal in the past in his classic Ford with 100% success.


2004 VW T5 2.5

I cant believe this product. I spent 700 gbp in a garage and they said it was water pump and something else. 20 miles later loss of water and heavy smoke again. went back and got

Followed the instructions to the letter and it does exactly as it claims to do saved hundreds of pounds and time used every day since used and it's running perfect highly recommend this product.

Had my Nissan from new, it has never broken down on me, symptoms were pointing to the head gasket being a major money problem, it was a case of deciding between selling my best ever car for scrap or buying Steel Seal as a last resort. £25 later, Wow! My car is back in the game, so smooth again. I'm really happy, it feels safe to drive again, I don't know what you did but thank you for the invention, worth every penny.

Flush antifreeze and oil out pour steel seal in run engine 1 2 3 all done running as new 10/10 top stuff 10/10.

John Kirk

Mitsubishi L200, 2005 2.5td

I was told to buy steel seal as a cheap alternative for repairing my head gasket. I was very apprehensive when purchasing this as there is a great price difference between labour costs of a mechanic replacing a head gasket and a small bottle of liquid that claims to have the same result, but i followed the steps on the bottle and sure enough, no more water loss, no overheating and saved me hundreds of pounds. 100% recommended.
