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

It's been a week now (500+ miles tested) since I've done the treatment on a 1.8L Toyota Prius that had codes for misfire cylinder on all 4 cylinders and I can honestly say it works but I followed these exact steps: Step 1: Cooldown It takes a car 4 to 8 hours for an engine to cool down but it will only cool down to the ambient room temperature, so I had to wait overnight for my car to fully cool down (I'm doing this in summer). Step 2: Drain & Refill Radiator I drained the entire radiator from the bottom, than pour small pot of hot water through the radiator reservoir to help clean out any previous antifreeze remnants. Closed it up, poured 1 gallon of tap water, than half bottle of Steel Seal, than more water and topped it off with the rest of the Steal Seal. Step 3: Drive 10+ minutes with 3500-4000 RPM I drove my car to the highway and then went about 7 miles and then made a u-turn to the next exit and went back on the highway. I did about 20 miles with 14 of it being highway miles. I made sure that I DID NOT turn on the AC/Heater during this trip because I heard about this stuff getting stuck in people's heater core, so I just avoid turning on my air. Step 3B: (OPTIONAL) Clearing Air Pockets I wanted to clear all the air pockets in my radiator so when the car was turned off, I briefly open the reservoir radiator cap (while it was warm) just for all the bubbles to push up and then closed right away before it could spill out. This will damage the reservoir cap so you will need to replace it eventually if it's not damaged at the moment. Which you're supposed to replace when you're doing this Steal Seal treatment anyways. Step 4: ENGINE COOLDOWN Now that the steel seal is all over the cracks, it needs to cool down for it to cure so I waited overnight for the car to go to a complete cool down before driving her the next morning. It's been a week now and I've been driving her normally, and so far🤞 there has been no check engine light, nor any rattling on the engine. If anything changes, I'll come back to this review 😅

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.

Excellent product

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

Disclaimer * Before using this make sure your oil doesn't look cloudy and milky. If this is the case your head gasket is broken on the inner side and water is leaking into the oil. This product will not fix that issue dont waste your money.* Okay heres the thing, this stuff does work BUT you have to follow the instructions to a T. If you think you're going to just poyr this stuff in and drive off you're going to waste your money. You have to make sure the cooling system is flushed out and the only thing in your system is water. Run it at the stated rpm range for the amount of miles instructed by the bottle and let it sit till its completely ice cold cool. I let my car sit over night. For the first week keep an eye on the coolant level and top it off with water and take it easy with the throttle for a while. Drive conservatively for atleast a week. I went from putting a quarter gallon of water in my radiator every morning before leaving the house to only topping it off a little bit to not having to put any water in as the week went on.

Head gasket on my 2011 Camry noticing bubbling the coolant reservoir so exhaust gases going into my coolant. After trying other products like k seal pour and go and bars head gasket and block seal I tried this. What I did was drain the antifreeze coolant out I the upper radiator hose off where it connects to the head of the engine and took my thermostat out and just flush water through the upper hose connection on the engine to let it come out where the thermostat sits.then I drained my radiator. And with the thermostat still out of the engine poured the steel seal into the radiator and filled it with water and let it idle for about 45 minutes and turn the engine off and let it sit overnight. Then first thing this morning put the thermostat back in after draining all the water from the radiator, the block and the coolant reservoir. Filled the coolant reservoir and the radiator with premixed antifreeze and I noticed my check engine light turned off and no more hard starting after a good long drive. I taught the radiator off the rest of the way seen no more bubbles coming from the radiator

It did not work for me and it caused clogging in the entire coolant system on top of gasket issue.

Great stuff to use for a slight leak in a head gasket, put it in and within 20 minutes the vehicle was fine.

Car was struggling, coolant being pressurised and car overheating. Used this not expecting too much, but car has been fine for nearly six months! Not really pushed it too hard, but for my day to day commute has been fine since use, even when stuck in traffic.

Works as designed. Saved us a new motor

Did not work. Waste of money and no refund given or response to my contact for advice and refund as stated on bottle

It didn't work and should be able to get your money back.

Coolant was seeping into my cylinders overnight which was causing misfires and check engine lights the morning after. I believe I caught the early stage of gasket failure and coolant reservoir maintained level after using this product. Tip: the instruction said to run highway speeds maintaining 4000rpm, which is not feasible. This can be achieved driving around your neighborhood in low gear and your speed will be slower to 30km/h.
