Two technicians were discussing hybrid organic acid technology (HOAT) coolants. Technician A stated that hybrid organic acid technology (HOAT) coolants use organic acid salts (carboxylates) that are abrasive to water pumps. Technician B stated that the pH of hybrid organic acid technology (HOAT) coolants is usually below 7. Which of the following about the scenario is true?

A. Only technician A's assessment is accurate.

B. Neither technician A's nor B's assessment is accurate.

C. Both technician A's and B's assessments are accurate.

D. Only technician B's assessment is accurate.

Black · Answer 1

B. Neither technician A's nor B's assessment is accurate.

Explanation:

Technician A is wrong because HOAT use organic acid with a low silicate inorganic corrosion inhibitors and it doesn't damage water pump as it contains azole additive which is a copper corrosion inhibitor.

Technician B is wrong because all coolants operate at neutral or basic pH range (pH equal to or greater than 7).
