Amount of coolant/water needed when flushing ONLY radiator?
 

I am going to be installing a new stat' and thought I might as well flush the radiator too. How much coolant/water will i need? As in how many gallons of water and cases of coolant? Just an approximate amount is fine, i dont need any 4.587.... answers:p

Buy 2 gallons of coolant and do a 50/50 mix (gallon of water for each gallon of coolant) I don't think the radiator will hold more than 4 gallons.
