Which brand contains silicates and phosphates

[Tron1]

I want a coolant that contains more than the minimum silicate and phosphates. My engine is cast iron, with aluminum heads with an aluminum radiator. At the very least I want both silicate and phosphates. Can you help?
Thanks.

Best you can get is Honda Type II, comes pre-mixed. Not too expensive either.

Original green formula is about the only one that contains both silicates and phosphates.

Yes, that's what I thought... I wanted a relatively low silicate with phosphates and sometimes it is difficult to to read through the haze of advertising/claims. Thanks.

Peak and Zerex make original green. Also Chevron and Shell make it, but not many places carry it.

NAPA has its own low silicate/phosphated American green coolant. I used in Kia and Isuzu. Avaible in 50/50 and concentrate.

FWIW, G-05 has been proven very reliable and effective in engines with your combination of metals (iron block, aluminum head and radiator). Its also got enough cavitation suppression to be approved for some wet-liner diesels.
