Question 1 of 27070

What would be the result of adding phosphate compounds into the cooling system of a diesel engine? Protect the coolant from freezing. Protect metallic surfaces from corrosion.

🔍 Key Concepts

• Function of phosphate compounds in cooling-water treatment • Difference between corrosion protection and freeze protection in diesel engine cooling systems • Role of antifreeze (glycol-based) vs. other additives in coolant chemistry

💭 Think About

• Ask yourself: are phosphate compounds primarily used to change the freezing point of water, or to change its chemical aggressiveness toward metal surfaces? • Think about what chemical is normally added to coolants to prevent freezing. Is that the same thing as phosphate, or a different kind of compound? • Consider typical problems in untreated cooling systems: scale, rust, and pitting. Which of the statements (I or II) sounds more closely related to those issues?

✅ Before You Answer

• Verify which function is normally associated with phosphate treatment in closed freshwater cooling systems • Confirm which substance is typically used to lower the freezing point of the coolant (name the common chemical family) • Check whether a single additive can reasonably perform both listed functions, based on what you know about coolant chemistry
