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.
Enter the cooling system. The cooling system is used to keep the engine from overheating. It does this by keeping the temperature at a constant so it runs more efficiently. The cooling system uses coolant to do this. Coolant is a 50/50 mixture of water and antifreeze. When you start your engine, a water pump circulates the coolant through the engine and radiator. Once the engine has reached a certain temperature, a thermostat opens to control the flow of coolant through the radiator.
