2-EHA free coolant for a 1990 Bentley

[Rick7]

Looking for the correct coolant for a 1990 Bentley. It must be 2-EHA free because of the Silicone O-rings in the engine. Suggestions? thanks

Didn't they still use old school silicate green back then?

Peak and Zerex still make original green silicate coolant. Otherwise, there's Zerex G-05 and Peak Global Lifetime.

I'm 99% sure they still used old school green in your 1990 Bentley. If they didn't use the old green, they used G05.

If you want something more modern, there's Peak 10x.

The Zerex G-05 lists no 2-eha in their sds and neither does the Zerex Asian blue or red. These are three options for you.

Just regular old skool iat green and distilled water

G-05 or JD Cool Gard II would be my picks.

As far as I understand it, carboxylic acids are all a detriment to silicon elastomers, not just 2-EHA.
