It worked well for cleaning it out and also cleaning out the rust off the cast iron block. I kept in in there about a month and around 500 miles with no issues. Easy to use and did what it claims without causing any issues. Just make sure to flush really good after using. Good option if you’re dealing with rusty or neglected coolant systems. Review: Incredible - My wife bought a 1966 van and couldn’t get it to cool after a new water pump, new radiator, adding a fan shroud, lower thermostat and about everything imaginable. Engine would overheat after running about 5 miles. Finally, as a last resort I thought maybe there’s some rust blockage in the system. Tried Thermocure with clean water and after running it for a few hours the system actually drained dark black. Engine runs cool now. Not sure what makes it work but it works awesome!! ## Features - EVAPO-RUST RUST REMOVER: Evapo-Rust effortlessly removes rust from automotive parts, hardware, tools, cookware, and antiques without any scrubbing or sanding. - THERMOCURE FORMULA: Thermocure is made of a non-toxic and water-based solution that is easy-to-use on automotive cooling systems.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Well for Cleaning Rusted Cooling Systems *by B***C on May 15, 2026* I had sludge from HOAT mixed with DexCool.

Engine would overheat after running about 5 miles. Finally, as a last resort I thought maybe there’s some rust blockage in the system. Tried Thermocure with clean water and after running it for a few hours the system actually drained dark black. Engine runs cool now. Not sure what makes it work but it works awesome!! ### ⭐⭐⭐⭐⭐ This has worked well for me but there are caveats, please read. *by J***Z on October 5, 2022* 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. ## Frequently Bought Together - CRC Thermocure Coolant System Rust Remover, 32 Oz, Rust Remover for Vehicle Cooling Systems, Removes Rust Scale and Deposits - EPAuto Spill Proof Radiator Coolant Filling Funnel Kit - Dorman 47016 Coolant Service Kit Universal Fit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/24456585-thermocure-coolant-system-rust-remover-32-oz-rust-remover-vehicle](https://www.desertcart.pe/products/24456585-thermocure-coolant-system-rust-remover-32-oz-rust-remover-vehicle) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-07-10*
