Which coolant to run?

Hey I found out that my radiator was leaking today so I'm getting a stock replacement soon for $150.
Is there a better coolant that I can get? I heard about Evan's coolant or something.
Thanks!

Thanks.
Anyone knows how much Evans NPG+ costs? How many bottles do I need?

$22-$25/gallon. You also need to perform the flush correctly.

Never run pure water in a car. You have no pump lube/corrosion/antifreeze/boilover protection.

I'm not a big fan of generic replacement radiators.
If budget is an issue, you have no choice. But, if budget was an issue, than $60 worth of antifreeze vs. $20 worth an antifreeze shouldn't even be a choice.

I won't badmouth Evans, but if you don't know the condition of the engine, cooling system(wpump/housing/other hoses/cap/thermostat), then it would suck to leak and blow $60 of antifreeze because of a possible future failure.
Now, if all your components are recent/new and you have faith in your engine, then go for it. But, then I would say buy the koyo/fluidyne radiator also.
And, while you're at it, make sure you are using a Mazda thermostat.

And, I always use the Redline water wetter. But, it isn't needed with the Evans because there is no water. And, I always use prestone yellow bottle green antifreeze. It never hurts my wallet when some hoses/seal/components springs a leak and is available everywhere for quick roadside repair/refill if necessary.

I dont think you know what youre talking about. Ive always ran straight water in my car during the hot days.

Just to get technical on it all...

Coolant != Antifreeze

Standard coolant in a 70 (water) / 30 (coolant) ratio. Works great, always has and always will.

Good for you. Doesn't mean you are right. And since you don't know me, don't judge me.

And, technically, breesej is correct.

Antifreeze-A substance mixed with another liquid to lower its freezing point.

Coolant-An agent that produces cooling, especially a fluid that draws off heat by circulating through an engine or by bathing a mechanical part.

As you can see, they are not equal.
Most major EG/PG producers call it 'antifreeze/coolant' or 'antifreeze&coolant' or 'antifreeze-coolant'. Most 'commoners' or 'lazy typers' will use one word or the other, but acceptable wording doesn't mean its correct.

I don't have a bottle of Evans. Since technically it doesn't need any antifreeze substances, I wonder if it is labelled a coolant only. If it is, kudos to Evans technical writers and engineers for practicing correct engineering and not acceptable engineering.

Dead, I'll look when I get home, I also havent had time to scan the MSDS yet. I believe the bottle is labled coolant. I will verify. Evans is ethylene and propolyne Glycol mixed. The percentages are on the MSDS. Which I have a copy of.
