Cooling systems, who runs what?

[wastedyouth02]

In response to the silicates in the coolant, they put it in there to basically eat away rust in cast iron blocks

The silicates literally "Sandblast" the coolant passages.....

when i rebuilt the 318 in my truck the sandblasting affect took out a good chunk of material right where the coolant makes a bend out of the water pump into the block

[dannygraves]

which coolants contain silcates?

which coolants contain silcates?

All of them that dont say "silicate free"...

When I got my stuff back from Glen, I asked what kind of coolant he preferred that I use, and he recommended straight antifreeze.

why would somebody use straight anti freeze? why would somebody recomend straight anti freeze? straight anti freeze is not a good recomendation

[AlisoBob]

straight anti freeze is not a good recomendation

[100hp honda]

if you dont need freeze protection, 50 water/ 50 water wetter looks to be among the best combinations

[100hp honda]

actually maybe just a pinch of water wetter is all you need i guess, but it looks like a great combination

[fastkart]

I'm planning on running 50/50 anyways... just thought it interesting that he said straight antifreeze. Just repeating what Glen @ GSS said...

[100hp honda]

i would like to try water/water wetter and see how well it works- but its waaaaay to cold here right now unless i mixed in some antifreeze. for a experiment im going to try 1.6 cap and straight water/water wetter this summer to see how it affects coolant temp

[M.F.D.B.]

Im willing to bet $$$ Glen meant straight 50/50 (or so) antifreeze as in, no other fancy stuff...

[fastkart]

It is definately possible that I misunderstood him, but I'm sure that he said to run it straight, and something to the effect of not messing around with 50/50. I remember thinking it was a bit odd, but also thinking he knows what he's talking about...

From Peak Coolant:

Why is it important to mix antifreeze with water?

Antifreeze contains chemicals that protect your engine against rust and corrosion, as well as freeze-up and boil over protection. Water is required to activate the chemicals in the inhibitor package. Furthermore, adding water to antifreeze actually increases the freeze-up and boil over protection provided. For example, a mix of 40% antifreeze and 60% water provides freeze-up protection down to -10°F and boil over protection up to 259°F. In comparison, a mix of 70% antifreeze and 30% water provides freeze-up protection down to -62°F and boil over protection up to 270°F. We do not recommend adding more than 70% antifreeze. This would limit the corrosion and freeze up protection and heat transfer capabilities of the antifreeze.

To make a gallon of coolant, use the number of pints shown of coolant, and distilled water.

The 20/80 mix works great! ( and its cheap, like Brit)

Mix Ratio-------Antifreeze----------Water

50/50------------- 4-----------------4
40/60--------------3.2--------------4.8
33/66--------------2.6---------------5.4
25/75--------------2.0---------------6.0
20/80--------------1.6---------------6.4
10/90--------------0.8---------------7.2

Ever wonder how products like "Engine Ice" work? Their 90% water!

I was messing around in the garage last night, and checked out the bottles of preston that I've got and all of them say silicate free (they list some others with silicate) and this is for the universal 50/50 mix, strait green stuff and the dexcool I have left over from the chevy. So I'm thinking the 50/50 prebottled mix stuff is fine!

[M.F.D.B.]

I run the Orange Dexcool stuff my self...when im out of the Honda...

[dannygraves]

I seem to remember the dexcool stuff having issues with certain seals, part of the reason the late vortec 5.7 intake manifold gaskets would always leak. I scarred to run it in anything that isn't GM.

No way holmes, I have run that shit in everything ive owned, ZERO problems. The reason the Vortec's leak is the junk-ass plastic manifolds that warp...

[dannygraves]

the lower manifold is aluminum... I had one... the plastic gaskets fall apart, everyone blamed the coolant, I thought it was just a shitty gasket design. I lost all of my coolant in about 30 seconds on the 215, it was crazy when I pulled it apart I found that the gaskets were replaced once before, sucks.
well, if the dexcool is safe I have 3 gallons of it I can now put to use.

@ 20%, I'd call that a lifetime supply.

50/50 recycled I have a 55 gallon drum! It costs me $150.00 delivered with a pump and waste drum and pick up the waste for free...

You must own a "green" shop.
