Steps to Treat Engine Overheating
A THERMOCURE® radiator flush is safe, simple, and easy to use. This product restores the engine’s ability to transfer heat to the coolant allowing engines to run cooler and essentially last longer.
Follow these simple steps to revitalize your engine:
- Drain coolant and properly dispose of it. Add 1 qt of THERMOCURE® into the radiator.
- Fill the radiator with clean water and drive it for 2-3 hours. You could drive it normally for 2-3 days for bad cases of rust.
- Flush the cooling system 2-3 times with water until the water runs clear. Refill the cooling system with a quality coolant mixed with water according to the manufacturer’s specifications.
Now your cooling system is ready to perform.
Customer Review
We love to hear from our customers. Here’s a recent one.
“I have a 2000 Wrangler that had a horribly rusted water jacket. I tried probably half a dozen different products; the rust just laughed at all of them. I heard about this stuff and decided to give it a shot. Flushed the coolant system and filled it with a bottle of this and distilled water. I drove it back and forth to work for a week and drained it. After everything I had tried before, I had low expectations, I was really jaded at that point. But when I saw what came out and then pulled the thermostat to check the water jacket, I was honestly amazed. The muck that came out was black, and the water jacket looked like a new casting. I couldn’t believe it. Many coolant system cleaning products claim something they really can’t back up; this is not that. THERMOCURE® is legit. If you have rust in your cooling system, this will get it out. Full stop.” Justin B.
