I’ve used the CRC coolant system rust remover a couple of times now. It does the job, but I wish the instructions were clearer. The rust did come off, but I had a bit of trouble with the application. Still, it’s a solid product for the price.

Good product, but beware of the smell
The rust remover works as expected, and my car’s cooling system is looking much cleaner. Just be careful with the smell—it’s quite strong! It's effective, but I had to make sure I was in a well-ventilated area while using it.

Didn’t work for my vehicle
Unfortunately, the CRC ThermoCure didn’t do much for my cooling system. It seemed to just sit there and didn’t really remove the rust as promised. I followed the instructions, but I’m not sure it was worth the money. Maybe it just doesn't suit my car.

Great value rust remover!
I was amazed at how well the 32 oz CRC rust remover cleaned out my old coolant system. Removed all the deposits and rust effortlessly. I’d definitely purchase it again for my next vehicle maintenance. Highly suggested for anyone looking to rejuvenate their cooling system.
