Question

all or the following are true about testing engine coolant EXCEPT. A. An antifreeze hydrometer indicates the coolants boiling point. B. An antifreeze refractometer displays the percentage of coolant to water. C. An antifreeze test strip indicates the coolants PH balance. D. The engine must be brought to operating temperature before testing the coolants boiling point.

Answer 1

The correct answer is A. An antifreeze hydrometer indicates the coolant's freezing point, not its boiling point.Explanation:A. An antifreeze hydrometer measures the coolant's freezing point, not its boiling point. This is the correct answer, as the statement is false.B. An antifreeze refractometer displays the percentage of coolant to water, which is true.C. An antifreeze test strip indicates the coolant's pH balance, which is true.D. The engine must be brought to operating temperature before testing the coolant's boiling point, which is true.Therefore, the statement that is not true about testing engine coolant is A. An antifreeze hydrometer indicates the coolant's boiling point.
