1. Drain
Drain coolant and add one quart of THERMOCURE.

2. Fill & Drive
Fill radiator to the top with water. Drive the vehicle for 3-4 hours up to several days to remove extensive rust.  You may drive the car normally during this period.  Once the engine has cooled completely, drain the cooling system.

3. Flush & Refill
Flush the cooling system twice with water.  Refill the cooling system with high quality coolant mixed to the manufacturer's specification with water.

Do not use THERMOCURE in freezing temperature.  THERMOCURE does not protect your engine from freezing.
