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.
The coolant in your system should be a 50/50 mix of water and antifreeze. Water is what pulls the heat out of the engine, but due to its high freezing temperature, low boiling point, and the fact that it allows corrosion to develop within the system we have to add antifreeze.
