Rust and corrosion act as insulators and cause vehicles to overheat. Is your engine running hot? Remove the rust and corrosion by treating the cooling system with Thermocure®. Thermocure® clears away that rust and restores your cooling system to stop engine overheating and return it to normal working condition. Here’s how.

Steps to Restore Your Engine’s Cooling System

  1. If the cooling system is very rusty, it may be beneficial to flush the system with water before adding Thermocure®. However, it does not need to be clean before treating it.
  2. Drain your vehicle’s system. (Make sure your car is cool—wait about twenty minutes after running the car). Place a bucket under the cooling system, open the petcock on the radiator, and drain your system. Dispose of the coolant properly. Close the petcock on the radiator.
  3. Fill your cooling system.
  4. Top up the cooling system with distilled water.
  5. Let the vehicle run without the pressure cap to remove the excess air; after the thermostat opens, replace the pressure cap.
  6. Depending on the rust build-up depth, run Thermocure® through the system for a couple of hours to several days.
  7. Drain and flush the radiator two or three times with cold water.
  8. Add a 50-50 mixture of coolant and distilled water to the radiator. Use a quality antifreeze to prevent future problems with your cooling system. 
  9. Thermocure® is non-toxic; however, the spent solution will have traces of antifreeze. You should dispose of it along with the antifreeze you removed from the vehicle. Click here for instructions on how to dispose of antifreeze safely
