Thermocure Coolant System Rust Remover, 32 Oz, Rust Remover for Vehicle Cooling Systems, Removes Rust Scale and Deposits

Did a really good job flushing out my cooling system. Gross how much crap came out after running this... I drove around for about 3 hours over the course of 2ish days, then flushed it out. I had to flush 6-8 times to get the water completely clear. I've since refilled with my normal coolant mixture and haven't seen any evidence of rust since doing the CRC flush half a year ago.

ممتاز جدا أنصح فيه

Finally a radiator engine flush that really works!! I tried Prestone and all the other brands with no luck!! This stuff cleaned out any and all of 44-years corrosion and sludge! Now the heat transfer is like brand new and car runs so much cooler!!!! Amazing stuff that really works forget about all the rest and go with the best Thermocure!!!

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.
