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.
Depends on the car. Also depends on the driving conditions. Same as in Vivek's answer. My Chevy HHR has a digital readout in the DIC that gives the current coolant temperature. Ranges from 84 degrees C to 102 degrees C (once the engine is warmed up). 88 degrees C would appear to be nominal. Above 92 degrees C and the engine is working hard.
