## Description

Evapo-Rust TC001 Thermocure Coolant System Rust Remover – 32 oz., Rust Remover for Cars Engines, Water Pumps, Radiators | Automobile Cleaning Solutions

Review: Amazing product. - This product really works. Fought with a plugged heater core for over 5 years, tried everything, I was going to pull the dash to change the heater core and tried this as a last ditch effort. It worked! Saved me a lot of work. Amazing product. Highley recomend.
Review: This has worked well for me but there are caveats, please read. - I have an older low mileage van where it appears that the cooling system just didn't get the regular attention a van with more miles and use might. This thing was probably stored for long periods of time. When I first bought it, it appeared to run hot at higher speeds but after some diagnostics the thermostat was determined to be the culprit. I looked into the radiator and it was an ugly rust brown mess. Several normal, no chemical additive flushes later the running hot problem still existed. At this point changing the thermostat probably helps but the corrosion in the cooling fluid, while it can be drained out, corrosion and scale would still be present on the heat exchange surfaces in the engine block, radiator and likely the now gunked up thermostat. Changing the thermostat without first treating the inner surfaces of the cooling system would only partially solve the problem. In this particular model of engine, a thermostat swap would also be a 3-5 hour ordeal - expensive. Enter Thermocure, and here are the caveats. Use it as directed but know that you will have to do more flushes to totally clean out the Thermocure. I did 6-7 post-Thermocure process before I started seeing clear water. What this stuff get out of your compromised cooling system is miraculous. On maintenance issues if I'm told to do it every 5000 miles, I do it every 3k. That's just me. I did the Thermocure flush twice, I used two containers, flushed a total of probably 10 times in all. But the interior of the cooling system is far cleaner, the van runs nice and cool, tak w longer to come up to operating temperature, and you can physically see the thermostat, now cleaned out, coming in and out depending on the stress applied to the engine. Before you use it, understand your vehicle's Hester core and why you have to run the heat in order to fully flush out your system. This stuff WORKS but know that you should probably take an extra step or two to get the best out of it. Simply adding some and draining the solution is only going part of the way. Add Thermocure, run engine for several hours, leave it in a few days, flush out solution, repeat, repeat several more times, repeat a couple more times in the interest of being thorough. This stuff works well and has saved me hundreds of dollars.

## Questions & Answers

**Q: Can this be used with antifreeze?**
A: No, using it with antifreeze will change its PH level and product will not work. You can only use it with water.

**Q: Can I put this inside a motorcycle engine to remove rust. (Not starting the motorcycle obviously)**
A: If your internals are rusted you're probably going to have to do an overhaul, because you have to mix this with water and it has to circulate then you have to drain and flush with water. It removes rust from the cooling system but it's like a thick chunky slime when you drain it. Now if you're using it to flush a cooling system it has to run.

**Q: 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?**
A: Needs to run

**Q: 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.**
A: Really depends on how bad your system is.
Mine took 5
But the solution does degrade in quality each time i used it.
Might need to start fresh.

### ⭐⭐⭐⭐⭐ Cleaned the nastiest coolant system I've seen
*by R***. on June 16, 2025*

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.
