How much coolant
How much coolant does the 7.3 coolant system take.
I am thinking about changing over to Evans coolant also how do you flush the entire coolant system is it the same as doing a gasser or is there a different way to flush a diesel.

well, it's spec'd to hold 31.75 quarts, or roughly 8 gallons. i've found that when you drain the radiator, that's about half of it. i flushed the coolant on my neighbor's truck when i did his oil cooler job.
since the Evans stuff is waterless, i dont know how youre going to get ALL of the water out of the motor, even pulling the drain plugs out of the block.

You will need a little over 7 gallons there is a link on the above page with how to do it. There are a few more hiding spots.
I went with rotella ELC (Red) due to the price of the evans

Thanks for all the info. Yes the Evans coolant is very expensive but it is the only one I have seen that you can put in the truck and not have to worry with any additives or testing every 4 to 6 months. Does anyone know of a cheaper waterless coolant.

I also use the Rotella ELC. You do have to flush out the system very thoroughly before you put in the Rotella. What I did was flush out the motor and save the old antifreeze in the recycle barrel, then parked the truck over a floor drain, removed both block plugs on each side. Put a hose down the filler of the bottle, turn it on, start the engine and let it idle for a short while until I was positive there was no traces of the old green stuff left. Let it all drain out, you'll never get all the water out so don't sweat it. Reinstall the drain plugs, pour in four gallons of ELC and fill it the rest of the way with distilled water.

I got the premix but the procedure Kwikk stated is how I did it except instead of floor drain i had several drain pans and buckets. While you are in there you might want to consider replacing the thermostat housing the OEM is junk
here was mine at 82K:
And also replace the upper hose with one that goes around the belt (Dual Alt truck) instead of through it.

www.dieselsite.com has a nice billet alluminum housing

And since the coolant will last longer than the belt you dont have to remove the hose to change the belt
