GET THIS if your car tends to overheats! Amazing!!
GET THIS if your car is older and overheats! I have a 1963 Pontiac 389 ci V*. It sat for nearly 40 years. It only had 28,000 miles but was always overheating. I bought this, and the first dose IMMEDIATELY cleaned SO, SOO, SOOOOO much rust and junk out of the system!! The motor cooling holes within the engine block were completely clogged and rusted. Although I had used radiator flush treatment, NOTHING worked like this! I drained this liquid (one container for every three gallons, I used 1.5 container for 3.5 gallons), and the junk which came out was amazing. I did a second treatment and AGAIN, more junk, rust, and "stuff" out of the system, just not as much. I drove the car hard, long, and let her get really hot, and it ran perfect! I cleaned out the second treatment and it was much, much cleaner. The thrid time ( I bought enough for 3 treatments,) leaf the system so clean. It was almost clear when it came out. AMAZING!!!

Works well - As advertised
Used the same product, after mixing according to instructions , in 2 old tractors. It totally cleaned the rust from the blocks and from the radiators. Both tractors now run very COOL.
The Power to Clean
Race Dendy send this message from Evapo-Rust: Hello, i wanted to tell you that Thermocure saved me from rebuilding my engine. i was having overheating issues with my all original 1987 monte carlo ss. the 305 engine has 32,000 original miles. I have tried everything else and the guy at Walmart said we heard alot of great things about Thermocure. so i bought it. i went home drain my system and put it in and drove it for a couple time a day for one week. i drain the system and the water was black. im not sure i can tell you how much the water smelled. It smelled like pound scum. I have never seen or smelled anything like it. mind you i have used all the other flushes from Walmart and my local part store. The anti-freeze that came out was clear and look good. Your flush clean something in the system that the other could not. i removed the thermostat and raised the system 3 times. I put new anti-freeze back in and the engine runs at 195 degree F. before it was around 235 to 245. i have a 195 thermostat in it. If this has not worked i would have been forced to rebuild the engine. thank you for such a great product.
