Q

Which of the listed effects would mixtures of ethylene glycol and phosphate compounds have on the metal surfaces of the cooling system of a diesel engine?

🔍 Key Concepts

• Ethylene glycol is commonly used as an engine coolant/antifreeze • Phosphate compounds are often added as inhibitors in cooling systems • Role of coolant additives in corrosion protection vs. system efficiency

💭 Think About

• Think about what ethylene glycol is normally used for in automotive and marine engines and what property it changes in the liquid. • Ask yourself why manufacturers add phosphate or similar compounds to cooling water instead of using plain water alone. • Consider whether a well‑designed coolant mixture is intended to damage or protect metal parts over the long term.

✅ Before You Answer

• Clarify in your mind whether ethylene glycol is associated with freezing, boiling, or flow restriction. • Decide what the primary purpose of phosphate inhibitors is in a cooling system: protection or damage. • Eliminate any option that describes an effect that would shorten engine or cooling‑system life as a normal, intended result of using standard coolant mixtures.
