1964 C2 Anti Freeze / Coolant

[George B.]

What is the recommended Anti Freeze / Coolant for a 1964 C2 Corvette? Engine is 350. And how full should the reserve tank be?

[Mark L.]

George, this question has been asked a few times. I'm sure there is something in the Tech Archives.

George, assuming you're still running your aluminum radiator in your 64, then Zerex G06 is the coolent, and the expansion tank should be half full when cold as indicated on the tank.

Don,

Maybe you meant to say G05 instead of G06?

This is what I just put in my ‘66.

The pre-diluted is more expensive than getting the full strength and then diluting with distilled water.

I had someone's new Z06 on my mind.

If you like the Zerex brand, you can also use Original Green. Do not use Dex-Cool, it is not good with older cars. Do not mix coolant types (IAT, OAT, HOAT).
