Dexcool

[BentleyArnage]

Blue Pentofrost. I run it in everything. Hate 4 different coolants, so I run the best. The second choice is the pink Toyota coolant. We use it in all the big semi trucks and a lot of heavy equipment. I'll run water before dexfuck. Hate the stuff. I don't care if they fixed it or not. After the misery I went through 20+ years ago, I'll never touch it. But that's just me.

Point taken, but my truck already has 263k miles on it so if the antifreeze takes it out, which is highly unlikely, then I guess I'll have an excuse to swap a 6.0/6.2 in... lol

No telling how many miles it will have before the antifreeze would have time enough to actually create an issue.

Pretty sure you’ll be fine but we can always hope for an early demise of your engine to make room for a 6.0/6.2!

Funny.... I see no less that 7 different Pentofrost varieties.

Please, don't hold back.

I switch my vehicles to Prestone universal. Dexcool does get nasty when you leave it too long which 99% of the world does. It also gets like clay if you have any leaks and air gets into the system. This is just what I have seen. I am not a hater I just don’t like paying more for a product that isn’t better than IMO than Prestone Universal anyway. I buy concentrate and mix it myself with distilled water as it is way cheaper.

Blue. Sorry. You're absolutely right.

Always have done the same. This truck is the first vehicle younger that 2010 and want it to last at least 7 years. I'll keep the dexcool as it seems to be okay in most. The guys running DEXCOOL you running mods too?

Out of those that responded in this thread, I'd roughly estimate that half have major mods such as a cam, heads or headwork, forced induction, etc.

Yep, blower, cam, etc. Now as for the intercooler- Whipple specs green 50/50 and a bottle of Water Wetter so that’s what I run in it but it’s a different system than the engine cooling system with its own pump, intercooler radiator etc but for the engine itself it’s Dexcool, that’s what’s spec’d for it. I’m kind of particular in my fluids, I run what’s called for as far as diffs, transfer case, transmission, power steering, which are all ACDelco fluids, brakes which are Wilwood calipers so I run their 500* fluid , cooling system, supercharger, etc.

Fleetguard ! - They have a good bit of info regarding Types/Compatibility/Life/Testing kits and replenishing additives. Highly reccomend a look if you have a varied Fleet.

Regarding Dexcool, are there differences between brands? Is Prestone the way to go?

 

[Smiley3303]

Brand probably isn’t that important as it is a spec so they are cooking from a recipe and I don’t think much deviation is allowed to meet that standard. If you don’t mind doing a little more work buy in concentrate and mix 50:50 with distilled water. Way cheaper that way.
