I purchased mine from Gemplers online. It was $22 a bottle but I've seen some guys buy theirs from Napa for as low as $15 but that was for in store pick up I believe. You will need 4 gallons of coolant and prolly about 21 gallons of distilled water.

are u deluting it or just running this stuff straight i know at ford we do half and half

3.5 gal concentrate and the rest distilled.

After flushing there is app 3.5 gallons of distilled in the heater core so the 3.5 gallons of concentrate will be 50/50.Watch coolant levels for a while the system will purge the air out

im going to flush with distilled and 3 cycles then u only need 3.5 gals of conentrate that seems low

The entire coolant system holds 7 gallons which is why you run your three cycles of straight distilled water (to dilute the tap water you had flushed with previously). Once you run your three flushes with distilled water, add the 3.5 gallons of NON-READY TO USE ELC coolant. It will mix with the undrainable distilled water that's already in the system. You then top it off with more distilled water to achieve your 7 gallons of a 50/50 mix.

As stated already when you flush the cooling system in the 6.0 even after draining the radiator and the heater core (if you chose to) and pulling the block drain plugs you will not be able to drain all the water out. There will still be about 3-4 gallons left inside so what you do is get CONCENTRATE and add it to the degas bottle straight up. (After flushing with distilled first a few times to get everything out) and thats it. DO NOT DILUTE YOUR FULLY FORMULATED COOLANT!!!! ADD IT STRAIGHT INTO THE DEGAS BOTTLE. You need about 4 gallons of concentrate to get between a 50/50 and 60/40 mix INSIDE the cooling system.

T6. Not as expensive as other synthetic oils and readily available at any walmart.

Here's a writeup I did for doing the coolant swap. You'll see Mitch (PGreenSVT) has some comments as well and he also has a very detailed writeup. Mine is just a couple loose tips like making sure you have the proper allen wrench sixe that you can use with a socket wrench.

Just changed coolant to ELC... a few notes for everyone
