Can this be used with antifreeze?
Can I put this inside a motorcycle engine to remove rust. (Not starting the motorcycle obviously)
Restoring a car that isn't running yet. Can I fill the system, let it sit for a week and then flush or does it have to circulate at warm temperature?
How many flushes did it take? I am on my fourth flush after using the solution and it still smells and the water is still dark.

Cleaned the nastiest coolant system I've seen

A few years back, the heater core on my 2002 S10 got plugged up. I took a gamble, disconnected it, and blasted it out with a garden hose. It worked—for a while. But within a year, it clogged again.I flushed it again and realized if it was getting that gunked up that fast, I should probably take a look at the rest of the cooling system. Sure enough, the coolant looked like rusty-orangey vomit. I drained everything, filled it with distilled water, ran it, flushed, and repeated. And every time, the water came out black and chunky. It was gross—and frustrating.After five full distilled water flushes and trying a few different chemical flushes, I still wasn’t seeing clear results. The gunk just kept coming.Then I came across this product. I added it to the radiator, ran the truck for a few days, and when I drained it—holy hell—it was nastier than ever. But after that? My flushes finally started running clear.I did a final rinse, refilled with new coolant, and now the S10 is running like new again.Bottom line: this stuff works. Yeah, it’s a bit pricier than other flushes, but it actually did the job—first try. Super easy to use too. Just pull out some coolant, pour this in, run the engine a few days, and boom—radiator clean as a whistle.

Great for rust in coolant system.

This is the product if you have rust in your coolant system. My race car runs only water so after a few seasons, major rust (bright orange water). Thermocool is the only cleaner product I find that gets all rust cleaned out. Fantastic product!

Let the product sit and do its work.

This product is absolutely amazing, and it works just as described. I had been suffering from overheating. I have tried several flushes with no good results, and I constantly have rust in my block due to the previous owner running straight water for an unspecific amount of time. But now, with one evaporation treatment, there is no longer rust in my block, my radiator, or my overflow tank anywhere. I would highly recommend you buy this product and utilize it.

Hard to remove

Put in Challenger RT as directed due the presence of rust in radiator fluid. Ran with water for 375 miles. When removed the water had the consistency of naval jelly, or a thick oat water, and reeked of sulfur. Fluid was very difficult to remove from engine. Had to fill, run, and flush the system multiple times. System even became clogged at one point and had to force clog loose with back flow water pressure. I’m not saying that my vehicle wasn’t a contributing factor, (however initial rad flush before treatment was added flowed freely) there has been cooling issues with this car since bought <6 months back. Despite my troubles the product seems to have completely removed the rust, and I have had no further issues, but I wouldn’t call the difficulty in removal confidence inspiring.This all said my parting words are to get ready to flush your engine more than you ever thought you would ever need or want to do. I don’t believe I make any exaggeration when I say that I probably went through a hundred+ gallons of water to get this cleared out.

It works!!!

This is the truth!!! I tried using Blue devil initially and it did not get the rust out of my 5.4 Triton. I bought this used it for 2 hours drove the car around. And this flushed all the rust out. I would buy again!!!

Amazing

I was skeptical of how well this would work. My cooling system was severely rusted. I went ahead and used this treatment. There is not a spot of rust anywhere in the cooling system. After using this product months ago I decided to see how my coolant looked. It looks brand new still. No more rusty brown coolant.

This product is AMAZING!!!!! SERIOUSLY.

I used this on a 1987 Toyota MR2 that has Sat a lot and despite being flushed a few times over the years, it had heavy iron/rust deposits in the entire system. This product works. I honestly didn't expect it to as the most powerful acid flush I could buy did touch the rust, but this did an amazing job. I still have some residual rust, so I'm using the product a second time to really get the system clean. This car had an 1/8" of rust built up in the inside of all the rubber hoses and this product is dissolving it. One use got most of it. Do not hesitate to use this, but make sure you flush your system to water before you add this product.....
