What Coolant is Best?

[Bdsankey]

I am getting ready to put my built motor together and am wondering what coolant I should run?

I was currently planning on running CAT ELC (the red stuff) and am wondering if thats my best choice?

Why are you against dexcool, if properly maintained it's one of the better coolants out there.

I agree, don't over think this.dexcool is good, so are others. Just buy what you can get and stick with it

I just flushed my system and chose to stay with Dex. Most of the horror stories I read about were from people that hadn't flushed their system in like 5 years.

Never had a problem with Dexcool. I was just talking about this to my father-in-law. I know know it’s at least 9 years old in my wife’s Tahoe if not 11. My in-laws have 12 years on their’s vehicles. I’ve had lots of our fleet vehicles that never get flushed.

Dex-Cool it is!

Does it matter where it came from? I am sponsored by the local GM dealership so it wouldn't be too pricey there or is someone else's formula better for dex-cool?

I'm OCD on fluids.

i run cat elc. easy too get(because i'm cat serviceman) and haven't found any better coolant. an it comes ready too fill, no adding water. never seen a engine with corroson inside with this coolant..

Any of it. I ran original dexcool in my LMM until the motor came out, 10 years, 103k miles, looks new.

Ran anything I had handy in the LLY and it looked and ran fine

Whatever you run, don't run the silicate based crap Ford uses. My brother swapped his 6.0L PowerStroke to Dexcool and saw a 10° temperature drop for coolant and almost the same for oil temp.

We run Dexcool in basically everything (including the Fords lol), never have any issues. Just swap it every 5 years and you won't have any corrosion issues. If you use the generic green stuff, swap every 3 years and you'll be fine too.

I run regular green coolant in everything. It has been around forever and hasnt caused any problems i am aware of. I have ran it in all my trucks and my wifes 12 suburban along with a 12, 14 6.7 powerstroke

I break something or decide pulling the motor is fun way too often to let it go 5 years between changes.
