ok...let's throw a monkey wrench into the equation...
Let's assume for sake argument that you did not get all of your old coolant out in the flush and you really only had capacity for 24.2 pints or 3.025 gallons.

So...if you put 1.75-2.0 gallons of straight coolant into a 3.025 gallon capacity coolant system you will have an anti-freeze concentration of 58%-66%! And I'm not counting the amount you "topped off with" when you bled the system. Dangeriously close to and well beyond the numbers stated in RAVE to avoid.
See direct quote from pg 119 RAVE:
"The overall anti-freeze concentration should not fall,
by volume, below 50% to ensure that the anticorrosion
properties of the coolant are maintained.
Anti-freeze concentrations greater than 60% are not
recommended as cooling efficiency will be impaired."
OK...now lets really throw a monkey wrench...let's say for sake of argument that Spike and others are correct and it really only takes 2 gallons to re-fill the system (similar to what I experienced...though I was closer to 2.5 gallons).
That means you filled your radiator with an anti-freeze concentration of 88-100%! (1.75/2 & 2/2) in this example.
WELL, WELL, WELL BEYOND 60%!

Thanks Spike555, I was told that the cooling system holds 4 gal of fluid. Is this correct? I only had put in 2 gal of straight antifreeze to mix with the already 2 gal of water in the system. Was I told the wrong info or am I ok with this presumption? Just did a search and found that the cooling system takes 14 qts. (3.5 gal). So I should be good with me mixture, right?
Me too, thats why I put straight antifreeze into the system. I was told it holds 4 gal but I only put 1 and 3/4 gal into the system after flushing. So I should be OK but if what I am hearing is correct then I will drain the system completely and refill with a 50/50 premix. I'll let everyone know as soon as I do this (probably tomorrow). Keeping my fingers crossed.

This is getting to be a dangerous tread. The recommendations from the forum in the how-to's has helped hundreds, from how to drain the system and refill/bleed. The recommendation is to get three gallons of pre mix and follow the directions. So start over with three gallons of pre mix, drain the system following the directions then refill following the directions and bleed the system. Worked on both of my Disco's. Started with three gallons each and they both used a little over two gallons each,not hard at all. Why are we doing this?

T-Stat not opening now, replacing it then taking it down to my local import shop to have him vacuum cooling system and refill with 50/50 premix for $90.00. Everybody happy now!
