Time to replace my anti freeze. Do people still use ethylene glycol? My Dart is a '69. It will be in there for a long time, and car is not used very much. Thanks
 
Green is king!

These days they have orange coolant and red trans fluid and blue oil. What's next?

I like having distinct colors for my fluids so I know what's leaking from where.

It used to be easy.

Green coolant
Brown oil
Clear or red power steering fluid
Red trans fluid.

That waterless coolant sounds like a neat product. Do you have any experience with it?

I use Evan’s. I won’t go back to anything else.

If for no other reason than it doesn’t make pressure.

It’s easier on the hoses, hose clamps and head gaskets. No pressure reduces the chances of leaks.

You can walk up to a hot engine and remove the cap and not have hot coolant scald your skin off.

And it does everything the others do and the stuff they can’t.
 
its illegal on the strip but other than that, sounds like a winner! That Dex-cool about ruined my Suburban. Going on a multi state road trip and we pull into an Albuquerque service station running a little hot. Right as I'm about to pop the hood, the stat housing blows out and dex cool shoots everywhere UNDER the still closed hood. What the hell just happened? There was a 1" chunk of that PLASTIC housing that blew out and vented the hot coolant seconds before I would have opened the hood. Dans chemistry lesson proved right, that **** softened that plastic enought to grenade it. The rest of the housing was so brittle it just crumbled under my hand. Autozone next door had one in chrome (oooh!) and it bolted right on, added more dex-cool and completed our trip. Did a full flush and used gool ol' green prestone after that.
 
I've always run Stant 7 pound Lev-R-Vent radiator caps on my old Mopars. Never had a problem, and less pressure in the system.

That’s a horrible stupid rule. When NHRA is paying for my equipment they can tell me what coolant to run.

And yes I’ve been to the track with Evans. When they start chipping about it I tell them exactly that.

They haven’t sent me home yet.
 
the "not allowed at the track argument" is usually

its more slippery so more dangerous if spilled
its flammable.

which doesn't make much sense
waterless coolant is propylene glycol
Normal coolant is 40-60% ethylene glycol
both glycols are flammable if you try hard enough

propylene glycol is more viscous then ethylene glycol, so in theory will have a greater detriment to grip, when spilled.
But at speed and on slicks, wet is bad regardless, no traction if the tyre doesn't touch the tarmac .

Mmmm

I’ve also been told it’s harder to clean up off the track surface.

It probably is. But my car is a street car and that coolant is legal for it.

So NHRA can suck it up and clean it up.

And you are less likely to have a leak using Evans coolant because it does not build pressure.

If the coolant is on the track because I hit the wall, caught on fire and backed it in to the hotdog stand (from my circle track days) NHRA will have enough clean up that you could use molasses for coolant and it would still be the least of the clean up time.
