SteelSeal Reviews 

Taucht nichts , zwei Stück reingetan und hat nichts gebracht. Dann stelle ich eine Geld zurück Anforderung und mir wird erzählt, dass ich das falsch angewendet habe.

Siguiendo el protocolo estricto recomendado por el soporte por correo electrónico (IMPORTANTE PEDIR CONSEJO POR CORREO), el resultado ha sido perfecto y la culata ha quedado completamente sellado al tratarse de una microfuga. Estoy muy satisfecho. Muchas gracias a Steelseal y a su servicio de atención al cliente.

I used steel seal exactly like the directions said to. And 30 minutes after using it my water pump went out. So I went and bought a new one. Put it on and it went out in 2 days. I had to flush my whole cooling system and put another water pump on it. I would stay away from this product

tried this product on two different vehicles and it failed to make a difference both times, so contacted steel seal for money back guarantee but no refund or free product as stated.stay away from this product as its not going to fix blown head gaskets.

Bin sehr zufrieden mit den Produkt hat alles Super geklappt kaum Ölverbrauch
Unfassbar.!!!!!!!
Habe SteelSeal bie Opel Mokka X angewendet der Wärmetauscher hat,s auch überlebt .

My car 2016 Peugeot 5008 has a blown head gasket and some drips of oil leaking from the engine but still running smoothly. I bought steel seal and followed the instruction video in their website. I left the car cool down overnight.The following morning I started the engine and the leak still persists. However, the coolant also started leaking profusely coming from engine. The problem has become worst! I brought the car to the mechanic and I they said there are lots of parts that need to be replaced. I ended up paying €1700 to change the blown gasket, water pump, timing blelt, alternator belt!

I put 4 star because it’s on going, bought a Mazda 2 for £800 as a first car run around, driving home the over heating light was flashing on the dash unfortunately brought as seen, tried a few things flushed the coolant system checked thermostat, no difference still over heating, a friend of the family is a ex mechanic he had a look he said head gasket is blown garage quote £1271.00 plus vat to repair, was going to scrap the car but I thought I will try steel seal first, I’ve never used it before but for £45.00 I thought it’s worth a go, put the steel seal in following directions on the bottle, unfortunately didn’t realise it wasn’t compatible with red coolant which I had in the car, any way it hasn’t cured the promblem completely after 24 hours took the car out for a run drove for an hour before over heating, bare in mind the car would over heat with in 10 mins of driving before the steel seal, took it out for a second run last night drove for 1 hour 20 mins no over heating but still a slight loss of coolant so better again on 2nd run will try again tonight if still losing coolant will drain the system and try the steel seal again with water and not red coolant 🤞

Total scam, it did not do anything but worsen the overheating problem. I ended up buying a head gasket to have it changed. Refund policy is a scam

I have used this on several vehicles for what has got to be well over ten years now, most it has worked on but some it hasn't...Absolutely no quibble when I've called/contacted them on any occasion, they will either refund you in full or you are free to try another bottle free of charge! I DO NOT understand where some of these other reviews (negative ones) have got there info from. This product and customer service have been awesome in my experience, using again today on my little Fiat Punto.

My car was having difficulties starting, smoking out white, low on acceleration power and consuming a lot of coolant. l went with it to a certain garage near by home, I returned the car four times to the garage after they failed to fix it and last time they said the head gasket needed to be replaced. I took my car home. So l came across steel and seal online and bought it and poured it in the car and after few hours the car was running fine upto date. No problems.

Don't bother it don't work waste of money cheaper to use k seal as you won't get your money back with steel seal. Email them get no reply call them get no where waste of £44.99

Used twice in 2 different cars. First was a Vectra with a h/g issue: - did nothing; zero. 2nd time it actually - would you believe - made the issue even worse than before. Absolutely scandalous product when the price and returns policy (which is a total con) are taken into account. Do not waste your money on this junk!

Says it has a lifetime warranty and money back guarantee but when you contact customer service they tell you it only applies if it's verified by a vat registered garage. No mechanic in there right mind would use this product and you would have to spend hundreds just to get your £50 back. I ended up stripping the engine myself only to find it had a minor gasket leak and there was no sign of the steel seal repairing the gasket. Replaced the gasket and it's fixed. Don't waste your money, you won't get it back. It's a con.

I’ve used SteelSeal 3 times on 2 different cars, every time it’s failed miserably despite its High cost. K-Seal fixed the car which is still running 30k later. K-Seal is less than half its price. SteelSeal have made it impossible to obtain a refund too !!! A Sham Product

has made no difference, again promise of refund in email but never actually got it, this company and product are trained by Houdini.
coincidence ? shock 20 minuets after leaving this blog I was refunded, thank you although I can still enlighten that the product never worked.

Absolute rubbish seller did not want to know when I asked for refund

Tried this on 2 vehicles now,one diesel,one petrol.both head gasket problems.never cured problem or even helped with any of these.used k seal a few times and I must say has always worked and is cheaper too. I know it is not the right way to repair a vehicle but some customers have not got the finances to repair the vehicle or only need a temporary repair to last a little time.don’t think I’ll use it again

Für mich rausgeschmissenes Geld ! Nach der Behandlung mit dem Produkt , genau wie vorgeschrieben , hat sich der Kühlwasser Verlust durch die defekte Kopfdichtung , verdoppelt ! Das ist doch Müll. Nicht zu empfehlen!!!

Tried steel seal to rectify a head leak,followed instructions,did 15 miles it blew coolant out.Being a self employed mechanic I got the car back to my workshop only to find that the warranty requires a VAT garage to verify the claim.I'm not prepared to have the car transported again so warranty is worthless as I will do the repair myself.A large engine so three bottles of Steel Seal down the drain,be warned.

I had a nasty coolant into oil breach with my MGF HG, it lost 3 litres coolant into engine.
I thought due to age of car it has to be worth a shot. Purchased from local Halfords store.
Followed instructions, replaced oil, and flushed coolant as best I could.
let it warm up with product in system, then 30 mins fast idle.
It was miss firing sometimes but used no coolant in that period.
Let it cool down, and did 20 min test run, no miss fire, no coolant loss.
Checked again this morning. coolant not dropped, another test drive it ran perfectly, no coolant loss or miss fire.
I have to say I was a little sceptical, but it does seem to have solved my problem, will probably need another oil and filter change to remove mayo.

It has saved me a big headache, and expense.

I think you need to prep the car as much as possible for best results, and a few heat up, cool down cycles required, and over night I saw the biggest iprovement with miss fire gone.

Happy days so far and I would recomend this first before you splash the cash, or book the scrapper!!
