new engine - what coolant?

[tomcat27]

I've got a brand new engine to install in a car that originally used green coolant. the new engine has cast iron block, aluminum heads and aluminum radiator. I figure it's best to use something other than green? G05?

similar story on an old truck - the new radiator is aluminum; engine is cast iron.

G05 should be good.

Agree. G05 is a good choice.

GO-5 but flush the green out totally.

The largest G-05 user (Ford) has switched to DexCool.

Chrysler has also switched from G-05 to OAT: http://articles.sae.org/11284/

Another vote for G05

G-05 would be my choice as well. It looks pristine in my Mazda 3, which apparently is allergic to the low silicate levels, along with all other Japanese brands, according to some experts here.

I would use supertech all makes all models
