Does not contain any odor, fumes or solvents. Thermocure cleans rust from radiators, water pumps, water jackets, engine blocks, and heads.

Review: Works Well for Cleaning Rusted Cooling Systems - I had sludge from HOAT mixed with DexCool. 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.

## 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.

### ⭐⭐⭐⭐⭐ Incredible
*by D***E on 1 July 2026*

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!!
