Toyota coolant in old GM car?
I was wondering if there might be any bad side affects to using Toyota coolant in a '69 396 BBC? I don't want to screw things up.
Thanks.

the red is a low silicant formula. over time silicants form acid and eat up aluminum heads/water pumps ect ect. the green stuff or gm dexcool (death cool) has a high silicant count and is responsible for a bunch of degraded aluminum parts (lots of acid)

not all of it, there aren't many high silicate formulas around any more. silicates eat away at the water pump, not cause acid erosion.

my toyota would've came from the factory with regular green stuff. i don't think it's worth paying twice as much as i do for coolant.
