1. Take pressurized reservoir cap off
2. Open petcock valve and drain Radiator
3. Close petcock valve.
4. Fill Pressurized reservoir with distilled water
5. Run car for 15 minuets WHEN operating temp is reached with heat on MAX and fan on HIGHEST
6. Add more water if needed WITH CAR RUNNING!!
7. Shut off car and let it cool off. (6 hours roughly)
8. Repeat step 2-6 four times
9. Open petcock valve and drain radiator
10. Close pet cock valve.
11. Loosen bleeder valve
12. Put 1 gallon of anti freeze (use the correct type depending on your vehicle) and 1/4 gallon of distilled water in reservoir. (to compensate for the water in heater core and block)
13. Mix 1/2 gallon water and 1/2 gallon of anti freeze then dump into the pressurized reservoir (Use funnel)
14. Tighten bleeder valve
