BMW 318i, 1998

Firstly can I say thank you Steel Seal. I am now 100miles on since having used Steel Seal and all is good so far. Prior to using Steel Seal I was having to top up reservoir every week until this led to a blown head gasket with

Vauxhall Corsa 2006

The instructions are really easy to follow. I used Steel Seal and straight away the symptoms disappeared. I no longer have white smoke from the exhaust and the coolant level stays constant. Brilliant and easy solution.

Maxine Cameron

Vauxhall Astra, 2007

Used the steel seal and ever since using it it has cured the problem thought I would have to fork out loads on a head gasket repair but used this and worked perfectly this was 3 weeks ago and still perfect, my new favourite liquid

Lewis Maxwell

MG TF 2002

My MG Tf developed a gasket leak with it spraying coolant all over the hot manifold and was completely undrivable.

I was recommended a competitor's gasket sealant which did absolutely nothing apart


Vauxhall corsa 2005

Found this product very useful, car was hard to start due to water in the cylinders, and when warmed up steam was coming from the exhaust like a smoke machine. One bottle of steel seal and 40 minutes later leak fixed. Does exactly what it says on the bottle.

Suzuki SX4, 2006

I was losing coolant after being stupid enough to let my engine overheat. I figured that I had most likely blown the Head Gasket as a result. I was told about Steel Seal, and figured I would give it a try. It was so easy to do...

Very good product done exactly what it said on the bottle .. will defo be buying again (:

Connor atkins

Peugeot 207 2007

Was very skeptical about the product at first, however it sorted my issue brilliantly. Will recommend in future!

Sam Ramage

Chrysler voyager, 2.5 d, 2007

I was the eternal pesimist when it came to 'miracle cures' . My local motor factor made it clear this stuff works but following the instructions of 'cold start' then run at full working temperature for 30 mins.... then "let it go stone cold.. preferably overnight " Did exactly that...


Range Rover 3.9 Efi 1992

Cured water loss off approx. 1/2 gall per 100 miles. This product saves a Head gasket replacement for about the cost of the head set alone.

Keith Briggs

Renault Trafic 2001

Very impressed! I used this as per the instructions (ie to the letter) and was so impressed with the results! Managed to get a few more years out of the van without any more costly head-gasket repairs. Highly recommended.

Mike Jeffrey

Citroen berlingo 1.9D 2002

Fantastic product!! My head gasket was on the way out as advised by a mechanic friend.... told it would be ‘costly’.

Not the case when I heard about steel seal! Awsome product fixed the fault and all seems fine. Would recommend and use again.



Vauxhall astra 2010

Had persistant sludge in the header tank and after a full radiator flush and antifreeze change the problem persisted. Used steel seal and the problem has gone. Excellent stuff,well worth the money.

Neil harrison

BMW 318i, 1998

Having been told the repair cost for a blown head gasket for my 1998 BMW E46 was going to be £400, I left the car for 2 weeks before reading about Steel Seal on a BMW forum. I was very sceptical about this product initially


Vw tiguan 2011

Used 1 bottle of steel seal via expansion tank, been driving for a month with no coolant loss works great highly recommend this product!!

Corrie dawson

Peugeot 206 2001

Used your product Steel Seal and it has really worked. My Peugeot 206 was really overheating and losing water, now all is good. Really good, five stars.

Craig Sadler

Ford Mondeo

My car kept loosing water and then overheating bue to the lack of coolant i searched and searched for a leak and couldnt find it i did a sniff test which came back ok a coolant pressure test that came back fine too


2008 1.4ltr Nissan note Acenta

I am very pleased to announce that steel seal is very fast and effective product to use to seal a corroded head saved me on a £300+labour,I only used one bottle, it's pricey yet it's worth every penny for its effectiveness.

Simon Charles Tolley

VW Touran 2007

My touran was losing 1 pint every 100 miles,not sure where from..Put in the steel seal and completely stopped the leak,very happy!!!!!!!!!!

Phil Willis

Ford Fiesta 1.1, 2001

Constantly loosing coolant over a 2 week period. I could see evidence of a slight leak on the head gasket. I emptied the expansion tank and added the steel seal. The leak slowed down almost immediately but I still had to top it up once in the following month. Now it doesn't need topping up. I suspect it needed to find its way to the leak. But its a great product.

Ford Focus mk2 2007

chris simmonds

Cameron Payne
