[QUOTE="RossKean, post: 1462143, member: 19880"] It is difficult to get more than that out (total capacity is 2.75 US qt. for Gen II) I'm not sure if that includes the 0.26 qt. to fill the reservoir to the max. line.) I think I would run it with that for a while and drain/refill once more. Your 50:50 is now somewhat less than that due to the 0.75 qt. of water remaining in the system but you will be very close with another refill. Plus, it probably gets more crap out of there... I normally just drain and refill with 50:50 without a flush but given the condition of yours, I would do as you did and flush/run with a couple of fills with distilled water first. When I changed from one brand of coolant to another, I drained, flushed x 2 with distilled water, added HALF the total capacity of the system with undiluted (non pre-mix) antifreeze and topped off with distilled water figuring this would bring me closest to 50:50 without wasting coolant. I would be tempted to do a chemical flush to clear out corrosion and mineral deposits, but you would run the risk of wrecking the radiator, especially if it is already corroded. [/QUOTE]
