A radiologist is a physician or medical specialist trained in obtaining and interpreting medical images. Images may be obtained with x-rays, (CT scans or radiographs), nuclear medicine (involving radioactive substances, magnetism (MRI), or ultrasound.
Without radiator coolant, an auto engine would overheat extremely fast, leading to mechanical breakdown and engine failure. While oil may be the lifeblood of a carâs engine, coolant is like the water that helps to dispel heat. In fact, coolant mixes with water in a carâs radiator. It prevents the water from freezing and boiling given the extreme temperatures it is exposed to.
Coolant fluid is a special fluid with additives, because it needs to remain liquid at very low temperatures (below 0Â°C), but must not evaporate at very high-temperatures (above 100Â°C). Coolant for cars also needs to have anti-corrosive properties in order to protect the metallic surfaces of the engine's various parts.
