Maybe I missed it, green verses red, should I replace the dexcool in my 96 Buick with EG green or drain and replace wih dexcool. also I heard you can dump dexcool down the sewer.[might be the best place for it].

If you have red keep it don't change in the middle of the stream!

I know what you are saying about not changing in mid stream but, I took the rad cap off and it looks like mud. I found the lower block plugs and I want to completely drain the complete cooling system and flush the b;ock and replace with Ethyl Glycol. what do you think?

Hey Steve! I talked to a buddy of mine this weekend who runs a BLOWN BBC in a 41 Willys on the street & runs pure anti-freeze in the ALUMINUM radiator & has no problem with overheating or corrosion. Your comments???

WHY?

Some of these Willys have radiators the size of Texas and it would cool with mud in it. How big is the radiator etal.

Does he run alky? Blown doesn't necessarily mean more difficult to cool. I have a friend who had a Scotty Canon Racing Willys on the street with a huge radiator and huge blower and it cooled just fine.

Pure antifreeze will have a severly reduced corrosion inhibiting and heat carrying cability. Even the manufacturers state this clearly on all their product bulletins. But you can do it, but it is less effective than a 50/50% mix? Obviously someone has given him some interesting advice or something?

Steve;
I'm just trying to figure out what to run in my new rad.
Do I really need a sacrifical anaode or not?
I don't know of anyone who runs one.

Fred,.....many people look at you funny when you mention an anode but there is a function that is needed there.

If you keep your antifreeze clean, use distilled water, it may be okay. But, you have to measure the voltage at the radiator to know if you really need one. But, the chemistry of your radiator changes with age and so forth. You risk holes being eaten in your aluminum at uncontrollable locations, including expensive heads I might add, and I think a ten dollar bill is good insurance. And that's me, I am a conservative guy when it comes to details about protecting my cars.

Steve what is your opinion on complete drain ,flush and refill with EG green? also is distilled water worth it? as for anodes Mcmater carr has anodes 3"
long with pipe threads about $5.00

Dave.....sorry to miss you previous post about the very same thing. I don't know why I didn't see it before. Now it's not only CRS (can't remember stuff..or whatever version fits), but now CSS (can't see ...... well, you know).

The radiator mud is common on aged dex. Because you have no EG (green) in there now, there is no reason to switch and go with green. It should be okay just to flush and run until clear and dex it back up with no fear of issues that were mentioned with EG and dex.

If you decide to go green, you will have to flush and flush and flush to prevent contamination of the EG. Now, it's going the other way that is bad in so far as fall out is concerned. A little EG contamination with PG is not a big issue. The other way around is catastrophic.

So, either way you chose, it's pretty safe.
