CRC Thermocure Coolant System Rust Remover, 32 oz – Rust Scale & Deposit Removal

CRC Thermocure Coolant System Rust Remover

Revitalize the pathways inside your vehicle with this 32 oz Thermocure formula designed for cooling systems. The solution is water-based and crafted to be non-toxic and non-flammable, making routine maintenance less burdensome for both your engine bay and your hands. It targets rust and mineral buildup that can slow coolant flow, helping you address stubborn deposits without heavy scrubbing.

Engineered for use in cooling circuits up to 3 gallons, this cleaner works within radiators, water pumps, and engine blocks to help restore clearer channels for coolant. While it doesn’t promise miracles, it presents a practical option to reduce rust scale and deposits that accumulate over time, particularly in older or poorly maintained systems. The result may be smoother circulation and quieter operation as part of a broader maintenance routine.

Three easy steps to cleaner cooling

1. Drain the existing coolant and remove the radiator cap, following your vehicle manufacturer’s safety guidance.
2. Pour in the Thermocure solution and add water to reach the system’s capacity.
3. Allow the cleaner to sit for 3–4 hours, or longer for stubborn deposits, then drain, flush 3–4 times with clean water, and refill with the recommended coolant.
