Antifreeze

Thanks Gil and Joe. I am assuming most of it will drain and be flushed during the 5 flushes I intend to do on the system.

Dale, I wouldn't it be easy enough to disconnect the hoses at the engine for dash heat and the AH and run clean water through them? Once flushed connect the hose returning to the engine and fill the line and then reattach the other hose for each?

Gil,

I took the hose off yesterday and energized the 24 volt servo to drain the dash heater. I will do that each time I fill and drain the system. Since I couldn't talk Paulette into getting in that drawer behind the front bumper, I removed it by taking out the screws.

I came across this from the Peak antifreeze final charge- Too good to be true- no flushing- converts old to extended. anybody have this experience? I have read many posts most say change regular coolant every two years, a few will or have flushed to then put in EC-1 compliant.

Q: My truck is using a conventional coolant, and I would like to change to FINAL CHARGE GLOBAL Coolant/Antifreeze. How do I convert my truck?A: With the FINAL CHARGE GLOBAL Extended Life Coolant Fleet Conversion Program, you can convert a truck using conventional or fully formulated coolants to FINAL CHARGE GLOBAL Coolant/Antifreeze without having to drain, flush and refill the cooling system. At the center of this program is FINAL CHARGE GLOBAL Converter.

A one-time dose of FINAL CHARGE GLOBAL Converter is specifically formulated to convert properly maintained cooling systems using conventional or fully formulated coolants meeting ASTM D-4985, ASTM D-6210 or TMC RP-329 to FINAL CHARGE GLOBAL Coolant/Antifreeze’s patented formula.

I would call the manufacture of Final Charge Global ... a place to start. In my experience you do not mix different types / brands and always change coolant filter once a year.

OWI in Illinois makes both Final Charge Global and DD power cool. Let's just say they are cousin's. Not that I have family that works there (wink,wink) or anything like that.
