The Correct Answer and Explanation is :
The correct answer is d. Blue.
PHOAT (Phosphated Hybrid Organic Acid Technology) coolants are typically blue in color. This formulation combines phosphates with organic acid technology to provide enhanced corrosion protection and extended service life for engine cooling systems. The blue color aids in easy identification and differentiation from other coolant types.
It’s important to note that coolant colors can vary among different manufacturers and formulations. For example, some OAT (Organic Acid Technology) coolants are orange, red, or pink, while others may be green or blue. However, PHOAT coolants are specifically known for their blue hue.
When selecting a coolant for your vehicle, always refer to the manufacturer’s recommendations to ensure compatibility and optimal performance. Using the correct coolant type and color helps maintain the engine’s cooling system and prevents potential damage.
