What is used to determine if the correct amount of coolant additives exist within the cooling system?

• A. Spectrometer analysis
• B. Test strips
• C. Thermal imaging
• D. Viscosity measurement

Answer: (B)

Test strips are used because they give a quick, on-site readout of the coolant’s chemical levels, including inhibitors and pH. You dip a strip into the coolant, wait a moment, and compare the color change to a chart to see if the levels are within the recommended range. This direct, rapid check helps ensure the cooling system has the right amount of additives to prevent corrosion and scale. Spectrometer analysis, while precise, is impractical for routine checks in the field. Thermal imaging shows temperature patterns, not chemical composition. Viscosity tells you about flow properties but not the chemical concentration of additives. Test strips provide the practical, immediate indication needed to maintain proper coolant chemistry.
