Question

Accepted Answer

With antifreeze protection of -60°F (-51°C), the boiling temperature could be 230°F to 250°F (110°C to 121°C).

Answer

A 100% ethylene glycol solution gives the greatest protection against freezing.

Answer

The boiling temperature of the solution remains constant at the level of greatest protection against freezing to -70°F (-57°C).

Answer

A 30% solution of ethylene glycol will protect the cooling system at temperatures of -18°F (-26°C).
