Glad we could help!

@@BarsleaksUSA in 2 years, it’s only done this once when trying to do a launch to see my 0-60 time. Can going WOT cause the head gasket to leak again or should I be good to push my car and increase my tune and stuff? I’ve been limiting myself under 400hp so I’d like to finally push it.

@@vwjet357 aggressive driving can cause the leak to come back, but when using our product if a good seal was made it is actually stronger than a head gasket itself.

@@BarsleaksUSAwhat happens if the seal breaks, but the product stops sealing it? This seems to be happening to me, even though it worked the first time. Still getting some bubbling in the coolant reservoir. That was originally fixed, before trying a WOT pull.

If getting some bubbling again you may want to flush the system and reapply. The product will build up a layer on the leaking area to stop the bubbling. Run the instructions a few extra times so that the seal is secure before driving @@vwjet357

It is required to install this into a clean cooling system at the proper dosage. Please make sure you have a clean cooling system with no Scale, Rust, or Debris.

@@Rick-qf5de you do have to worry about scale rust and debris, this can cause restrictions in your cooling system if you add our products. Only install into a clean cooling system with the proper dosage.

I hear ya, doing a frame repair on a 2004 Silverado the frame looks perfect, and the customer asked me why is my cab to close to the bed, well I told him they did a quick fix, welded the frame bad job, and uses filler and silicone to cover it up, good for the owner of the truck, but you cannot sell a vehicle to an unsuspecting buyers this way,

if installed at the proper dosage in a clean cooling system no this will not cause any damage.

This will not restrict anything if added at proper dosage into a clean cooling system.

I suspect the heater core and radiator may get clogged.

@@BarsleaksUSA How do i clean the cooling system. My mechanic tried flushing my engine for three days. The radiator and all water hoses are brand new. What will remove all rust and debri?

@@charlesevans9916 not in a clean cooling system.

@@charlesevans9916 any cooling system flush product should remove all scale rust and debris. rislone.com/products/hy-per-cool-radiator-cleaner-super-flush/

If added at the proper dosage in a clean cooling system you will have no issues with restriction as you are claiming.

@@BarsleaksUSA I worked at a used car dealer who actually did use this stuff on cars they would flip. It was used as the instructions specified including the fill and drain and yes absolutely it would clog radiators, heater valves, and cooling channels in engines. Never once would any single one of those cars pass a chemical combustion test for headgasket leaks, even if we dropped and replaced the coolant as was standard practice before allowing a customer to take it to their own mechanic for inspection.

@@kg4boj just draining and filling with fresh coolant does not clean your cooling system. You have to run a flush product to get the scale, rust, and debris/sediment out. If you just did a drain and fill yes it is potential for restriction your not cleaning the system before adding the product as it states only add to a "Clean" cooling system.

@@BarsleaksUSA You mean blue devil flush etc.. Used them. None ever get the crap out of any sort of modern radiators, the passages are just too small. Reminds me of some junk gun makers who tell you the 'break in' period is 5,000 rounds... well that's also the service life of life of the gun. So basicly you keep stacking requirements until the customer gives up trying to get their money back. Tell you what? Would you let me add this chemical to your wife's car? We'll make a video of it and put tamper evident seals on everything.

@@kg4boj Yes after a proper flush, if she had a head gasket issue I would add to my wife's vehicle. If you are not satisfied with the product you can get your money back we have a full refund on the product. Try Rislone Hy-per Cool Radiator Cleaner and Super Flush (p/n HFL400).

Thanks for the comment!

No, that is not the case we offer a refund on the purchase price of the product, not a new engine. Read the refund on the side of the bottle and it will explain everything in detail and how to apply if the product does not work.

BS newer use garbage ...you make more problem for engine .. Replace gasket ! Don't spend time and money !

@@nd2713 this will not cause any harm to the engine if installed properly into a clean cooling system at the right dosage rate.

LOL NOT if they are selling out of China or India to the US. How can you sue ? The seller is usually the president's cousin.

@@wildthoughts6959 we are made in the USA. We have a Guarantee that we stick by. We have been a family owned business for the last 75 years and pride ourselves in customer service and support if needed.

If it's snake oil, how come when I used it in Jan of 21 it's held up w/out any problem in my 2010 Prius. Still going strong at 245,000 miles. I'm a Believer! 👍👍

We have had many success stories with our products, as you can see from the customer above. When used at the proper dosage in a clean cooling system this product is the most effective product for a head gasket leak ON THE MARKET! Some do not have the funds or time to fix the issue via a mechanic right away and need some time to get things in order first. Our products help with that. Have you ever tried our products?

​@@BarsleaksUSA no, the most effective fix for a head gasket leak is A NEW HEAD GASKET. Maybe even get the block and head surfaced too.

@@jackbankson927 yes if able to fix the issue mechanically that would be the best option. But like we stated, some do not have the time or money to put into a vehicle that may not be worth that much. Or they may need time to save up to have it properly fixed by a mechanic. All of these reasons are why we make the product, we do understand that this product will not replace a mechanic but it can help until you have the time and money to get your car to one.

What i believe fix head gasket i repair not throw bottles but if it works more power all my rides will be properly repaired by me

Thanks for the comment! Glad we could help!

How much did they pay you to lie?

@@Bud88883 This is the best product to fix a head gasket on the market.

@@BarsleaksUSA Has that claim been backed up by any independent reputable source?

My mechanic told me that there is too much rust and stuff in my engine to try and use any product to seal it or even try to prolong the use of my engine. This add came up on my phone without me doing a search on head gasket repair products. I was in an auto parts store today only looking at the stuff. I did not take pictures did not talk to anyone so how did my smartphone know I was interested in head gasket repair products? Somebody please explain this to me.

What was the issue you were dealing with before installing and how long have you had the product installed?

If added at the proper dosage in a clean cooling system you will have no issues with restriction as you are claiming.
