Steel Seal Blown Head Gasket Fix Repair Sealer for 4 Cylinder Engines

This product really works! Besides that, they have the best customer support I've ever encountered in the automotive realms. My Subaru Outback was a gasket basket-case and the other inferior goops and leak fixes not only failed-they made matters worse. STEEL SEAL did the job and the engine hasn't overheated in months now... Great product-great company.

The bottom line for this stuff is that it might work or it might not. The ONLY right way to fix a leaking head gasket is to replace the gasket and possibly resurface the cylinder head if it is warped. Yes, this can be very expensive if done at a independent shop or dealer but if you are able, do the job yourself and save a lot of cash. I am doing the job myself for less than $400 including a new timing chain kit, head resurfacing, hoses, thermostat and a radiator. This "magic green stuff" not only didn't work, it clogged the cooling system on my 2004 Honda Element. Steel Seal support says it doesn't do that but I could see down into my radiator from the cap that channels were clogged. My engine nearly overheated during a short test drive after the treatment. Heed the warnings here and in the other negative reviews. You are rolling the dice with this stuff: might work, might not. Might clog your cooling system. You have been warned. On a positive note, Steel Seal was responsive to questions and did ultimately refund my money. Just be nice to them and you will get responses.

The media could not be loaded. I had a check engine light on with ABS light. Did the usual fixes - changed the fuel cap, reset the codes, etc. As the car was 100k plus miles, so replaced the spark plug. After a while the check engine light came back. The code check was P0304 - cylinder 4 misfire. It was a head gasket leak - bubbles in radiator and smell gas in coolant. Got the hydrocarbon tester from OReily's and it confirmed. I checked the engine oil cap but it didn't have any residue. I also removed a little engine oil to check if coolant had gone into engine. I didn't find any major trace of coolant. However, the coolant was going down and I had to fill up coolant once a week.This is when I decided to try the head gasket sealer. I removed the thermostat, filled the radiator with normal water. Followed the instructions mentioned in the pack. Once I added the sealer, kept engine running for 30mins. After this, I drove the vehicle for 15 - 20 mins on free way at 3000rpm. Left it to cool overnight. I had reset the engine codes and drove the car around. The check engine lights didn't come on. I have been driving the car for more than 3 months now. I had no issues with this - no check engine light, no gas smell in radiator / hydrocarbons.I can only upload one video, hence can't show the video where there are no bubbles.

Thank you for your attention. Unfortunately.treatment to my car was unsuccessful. Iused as directed. I took in to be checkedThis product did not help me

So I think I should of flushed better before using on 2000 cravings that was building a lot of pressure in the radiator I bought the car because I thought it just needed a radiator so any one who sees on market place someone saying a vehicle just needs a radiator pay attention to where it’s busted this one was busted on top like a chunk blew out of it and I as a human being learn by mistakes I should have realized that it was a head gasket issue from building pressure threw a cylinder leaking but it never crossed my mind anyways I told customer service they have a replacement product otw and fast I am not sure how anyone can say that they can’t get ahold of them you go to refund then contact seller !! It’s easy !! I recommend this product to any one because you have nothing to lose if it don’t work you get your money back and fast these ppl are amazing god bless ! I mean I don’t see any other product on the market that will refund or replace their products hassle free

1 star cause it didn't work for me in fact I'm losing antifreeze faster now, but overall it's worth the chance to try it to save over 1k in repairing the head gasket, my case now I'll just buy a newer truck and not fix the head gasket. I was told by close friends it has a 80% chance to fix it.

good product

Like the title says, if you are trying to cheap-out and avoid a head gasket replacement, this is one of the options. It is hyped on several YouTube channels and I know a mechanic that used it himself and it worked out. However, it did not for me, and may have damaged the heater control for the interior heat - not sure about that though. It did not seal the head gasket very much. Maybe it helped a little, but I had to eventually use another product that worked better (am I allowed to name it?). One big disadvantage is how much you have to add. This bottle says it's only for up to 4 cylinders and I should have used two bottles. Sorry, that's just too much money and stuff to get into my radiator. I only had access to the overflow, so two bottles wouldn't even fit. I could not find the drain stopcock (I'm not a mechanic) so I couldn't remove some of the existing fluid. I had to let the level go down from the leaking head gasket (came out as white smoke at startup) before I could gradually add this whole bottle into a V6 Toyota. If the top head had been the problem I would have had the gasket replaced but the bottom head is inaccessible, so the engine has to be hoisted out. I'm just not going to put that kind of money into a 150,000 vehicle.So, bottom line is, it's too much money, too much liquid, and insufficiently effective. I was offered a partial refund, which I accepted. Message me through Amazon if you want to know the successful product I came across at NAPA.
