so I just bought a aluminum radiator(check it out in my build thread) and ive never used an aluminum one before so im just wondering do i still use green coolant or do i use that orange dexcool? ive heard the green causes corrosion to aluminum but idk
thanks

 

I use the green stuff in my FD. It has an aluminum rad. Before I bought the coolant, I read the label to make sure it is recommended for use with all aluminum rads. hope this helps.

 

use the green stuff, just don't buy the cheap crap.

 

Don't ever use DexCool. There was a class action lawsuit that GM lost in 2008 (link below) that says that it eats "intake manifold gaskets and other engine sealability components".

Use the green. Don't go cheap.

 

Any quality name-brand antifreeze is aluminum-safe these days... and seeing as your rotor housings are aluminum, that's probably a real good thing.

 

i'll 3rd that, the rx7 just uses normal green coolant

 

thanks guys

 

keep us posted with pics of that radiator install what kind of 3-fan are you planning on using?

 

Anyone have anything to say about using Red Coolant? Like what you find in Toyatas? Just wondering because I work at the dealership so for me its hella easy to get the stuff. and cheap to boot!

 

I will throw in my 2cents stick with the green.On the toyota if your talking about the stuff they used for years its the same as green just dyed different. I sell new and recycle antifreeze for my job. Just make sure it does not say dex-cool or extended life.

Stick with the green stuff!!! Dex cool is for gm cars only and is crap if you live in an area that gets cold and the car sits for a while the stuff gels up and will clog your rad heater core and what not. as for the toyota stuff ???? All coolant is corrosive though thats why its not good to let cars sit for long periods of time with coolant in them.
