Question

Quizplus · Accepted Answer

High-silicate antifreeze is recommended for engines with aluminum heads and/or cylinder blocks because it provides better protection against corrosion and erosion of these components. It may also be used in engines with cast iron blocks and cylinder heads, but it is not necessary. It should not be used in any diesel engines.
