I just changed the radiator fluid on my 99 GT...I thought I was supposed to use almost 2 gallons of anti-freeze and I just used 1 gallon of anti-freeze and 1 gallon of water??? Is this right????
I drained the radiator put fresh water, ran the car with the heater on for 10 min. and drain the water. I this again 2 more time following the same procedure. After that I drain the water 1 last time and premixed 1 gallon of water and 1 gallon of anti-freeze and pour it in...with that it filled up. Then I ran the car for 15 min out in the road with the heater on and everything seems ok... Did I do it right??? I did I miss something that didn't flush the whole system???

No the car wasn't in incline...but I thought thats what the water pump does...no need to have the car in incline the water should eventually get pumped out of the heater core for re-serculation byt the water pump???

The water pump would only pump water out of the car when the motor is running. I assume you didn't drain your coolant with the motor running.

No the car wasn't on. But if I drain the radiator fill it with fresh water turn on the car with the heater on the water inside of the heater core would get re- circulated along with the fresh water. My point was to get fresh water into the core and circulate the old water out which is should've by running the car with the heater on. I think I'm OK..someone else in another board said 2 gallons of mix (50 water 50 Anti-freeze) is all you can fit in the radiator.
