How much better is water than 50/50 coolant?

40/60 antifreeze water usually. 84 and 85 308's get about 20/80 with water wetter because of their cooling system deficiencies.

Some track events require no antifreeze so in those we run water/water wetter. It is an anti corrosive and H2O pump lubricant and some of our customers have run it as a permanent mix. In this area freezing protection is really not an issue but on A/C equipped cars freezing protection should be used to prevent the heater core from freezing and cracking when the A/C is going.

 

I have rodded my rad a couple of times - way back when I first bought her in 97 but traffic was still warming it up more than I thought it should. My next move is a Griffin radiator. I need to mail mine in for a template so that is going to be a winter project

My fix for the past half decade or so has been water wetter and straight up distilled water.

It gets hot down here in the summer and I have never had a boil over. Not even close. Just make sure you have antifreeze back in for the winter.

 

OK.....

 

Same here.

Drive Safe.

Let's hear about it again on year 62 !!!!!!!!!!!!!!

 

so this all makes cents now,I guess. thanks rifledriver

 

I was referencing the use of water wetter as a "ghetto repair". I just naturally assume that WW was never marketed as a "ghetto repair" method, but an enhancement to an already proper cooling system.

I never realized what you spoke of concerning the AC and freezing the heater core. Do you think this is a problem on my older 80's vintage gtb's? I ask because i have been toying with the idea of running water/water wetter in my cars now, since i came to this thread. I live and drive in So. Cal mostly. How much of a mix do you think i must run to be safe if i need it, i run my ac all the time as i prefer to keep my windows up. Thanks for your knowledge.

 

I had to look it up. I was always concerned about the water/water wetter combination aswell but wanted to run it. Specially with my experience with jags and severe corrosion. What was it that the jag guys use to run? Some sort of oil?

 

I have to admit I have never seen it happen in a Ferrari so maybe because of A/C efficiency or plumbing issues it cannot. But it is a known problem in some other makes. I would think 10 or 20% antifreeze should be plenty.

 

GREAT thanks!

 

Griffin are supposed to be awesome radiators. I just had one custom made for one of my cars. I got a 2 pass with 1 & 1/4 passes. It was expensive but hopefully well worth it. If you want an update after I get it and install it I will let you know.

 

100% distilled water, and how much water wetter?

 

I use one full bottle.

 

And not to forget, it's not only outside temperature, but humidity as well.
Here in NJ, it's hot & humid so running high temps with high ambient temps (above 80) at any speed under 40mph seems normal.
Sitting in traffic at the lincoln tunnel (actually, being tri-state, when aren't we sitting in traffic) I've seen water temps so high I've had to pull over & pop the hood.

I run 25% antifreeze in summer and that seems to perform the best.
I've had my radiator out about 2 years ago & the core inspected & it was clean, so that's not it.
A buddy has had a Norwood aluminum rad put in his 85 308 - No signficicant difference.

 

Zerex makes a racing coolant for engines that require no freeze protection. It would work for those in mild to hot climates. http://docs.google.com/gview?a=v&q=cache:XziaxsFPlz8J:www.valvoline.com/products/Zerex%2520Racing%2520Super%2520Coolant.pdf+zerex+racing+super+coolant&hl=en&gl=us

 

One off-the-shelf size, or bigger one than that?

 

off the shelf,I think its about 8oz

 

Thanks, appreciate the info.

 

If you go this route just PLEASE go to Wal-Mart and buy distilled water. You don't want the inside of your entire cooling system to look like your shower head.

 

In NC, you get some cold winters, do you not? The primary function of AntiFreeze is exactly that, as some others have stated. Be careful you don't expose your cooling system to the potential of freezing.

In extreme heat environments, water will cool a bit better. I run distilled water/coolant in an 80/20 mix with Redline water wetter in my single turbo Supra (800 rwhp) here in Arizona. It is a "Sunday driver," but I have run it regardless of outside temperature, including days that have been 115+ with the A/C blasting and the car has never overheated. My tuner runs the same mix in his DD road coarse car, and it too has had no overheating or corrosion problems in 4+ years.

 

I've searched these coolant threads so many times and just end up confused.

This is what i gather though..please correct me if wrong.

Distilled water is corrosive but cools better?

Antifreeze is just to prevent freezing but has some anti corrosive properties too?

Non distilled water leaves deposits but distilled is corrosive?

Water wetter cools more than water or antifreeze and has some anti corrosive properties?

What to run in a 308 in florida where it never freezes?

Would the antifreeze non corrosive properties counter the corrosive properties of distilled water?

 

Yes they do. And those OTC coolants that are premixed 50/50 come with distilled water.

 

So the corrosive nature of distilled water is a lesser evil than the mineral deposits left with tap water?

 

103F outside here in Dallas. Think I'll just leave it in the garage.

 

Well, it depends on your tap water. Some localities waters are loaded with minerals, others not. Distilled water is no longer corrosive once it is mixed with coolant, water wetter, etc. There are discussions on BITOG in the coolant forum about distilled vs deionized vs tap, etc. You might try searching there.
