radiator fluid? red, green?
radiator fluid? red, green? alright i did the t-body bybass freebie mod and some red antifreeze came out i fill up wat was missing with water,but i will like to replace the fluid.but my question is which one do i use red or green?and if red were do i by it at?
You need "Dexcool". It is pink colored and you can buy some at any autoparts store.
If you live in a hot climate, you can just use water to top it off. Water actually has a higher thermal conductivity rate compared to antifreeze, so your engine always runs cooler on water.
I typically use 25% antifreeze and 75% water. (Texas summertime)

It does. I dont know what this guy thinks. Water has boiling point of 273degrees (F) whereas the average boiling point of cooolant (red or green) is 370 degrees(F). I feel sorry for that Texas LS1.
Oh, and by the way, mixing green and ared coolant is asking for trouble. Some coolant says that they can mix with any color, but if you have a $6,000 drivetrain, dont you think you should protect it with what is reccomended? Answer is GM Dexcool.
(50/50 mix, not 25/75)

Thats why he didnt say boiling point, thermal conductivity is the measure of a materials ability to conduct heat. He is simply saying that water conducts heat better than antifreeze which will make your engine run cooler, boiling point has nothing to do with it, whether or not its true I have no idea but it seems to make sense due to waters very high potential thermal conductivity. I would bet antifreezes potential is lower than water.

Verdad Gallardo In fact I have an old truck thats probably been running about 20% antifreeze 80% water with no problems for years now. Been hoping it would kick the can last few years so I never do any maint on it, its been going strong for a while in SoCal.
There have been a few (some lengthy) threads about this and it always seems to end up at a draw. If one completely removes the dex cool sucess can be had with the green. Usually the people using green have had contaminated dexcool causing sludge to form in the cooling system and block passages and get fed up and switch. Whatever one you choose, don't wait until 100,000 miles to change it.

I agree with your theory about the conduction of heat (Hell, heres the definition)
Thermal conductivity
Conductivity \Con`duc*tiv"i*ty\ (k[o^]n`d[u^]k*t[i^]v"[i^]*t[y^]), n. The quality or power of conducting, or of receiving and transmitting, as heat, electricity, etc.; as, the conductivity of a nerve.
Thermal conductivity (Physics), the quantity of heat that passes in unit time through unit area of a plate whose thickness is unity, when its opposite faces differ in temperature by one degree.

but when you slap water onto a block at around 240 degrees, there is a chance for flash boil and condensation: hence, evaporation if you remove the cap or de-pressurize the system. Regardles of ability to conduct or not, water is water, and all im saying is that water alone cannot withstand the forces of heat that cooland/antifreeze can. Granted, coolant/antifreeze is only at it's best with the addition of water, but that by no means makes it more "heat worthy" as Texas was making it out to seem. I live in So Cal as well, but I've never ehard of the 20/80 or 25/75. Hey, if it works, thats great- i might have to check it out!

Phoenix, I totally agree with you, the potential for flash boiling is exactly the reason why you should have the proper level of antifreeze in the car, you know and stated this. I'm just saying it can work, the 20/80 in my truck isnt on purpose, it has a leak that comes and goes for whatever reason. It seems whenever I pour antifreeze in (the only one that costs money), the damn thing starts to leak, so I just said screw it and left it alone. Like I said above, I have no idea if its true or just as good having less antifreeze in there, I was just trying to point out that what he was trying to say didnt have anything to due with the difference in boiling points.

I see. Oh- another thing... be careful with mixing colors if you dont know what was in there before 100%. Even if the coolant/water mix seems orange/red/pink; there still can be a problem. When the most common radiator/gasket stop leaks are added, they tint the green a different color- hence, the orange. I watched as a lesson was learned on my friends Twin Turbo VR4 ( I know, rice talk). Anyway- now he's not sure if it's a cracked block, or just the head gasket. Either way, he's got some work ahead of him.

I have a '95 T/A and use 50/50 green. The LT1 runs hot (~230°F) in stop and go traffic but cools to a steady ~180°F above 50mph. This tells me that the radiator seems to be doing the job but the fans are not sufficient for stop and go. With the air conditioning on in stop and go it runs cooler at around 210°F. I know the fans are on with the air compressor working making the water temp a little cooler. But without the A/C on, the fans kick in at ~ 200°C. Why the cooler temp with the A/C on? Its been like this for years and I haven't figured it out. I have flushed the coolant a few times, there's a new water pump, thermostat, and radiator cap.

Yeah... those 305 and the 350 L98 cant idle for the ****... my bros had three and my friend had one before he bought his LT1 (and I did mine). The LT1 ran way cooler than my new LS1 when driving, but I didnt have too much control in stop and go. Nonetheless, stop and go, driving, etc. I've never seen mine go a hair past 240. And just to let everyone know, a good full radiator flush is reccomended every year of 12,000 miles.
