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.
Engine coolant temperature exceeds approximately 106C (223F). A/C refrigerant pressure exceeds 1310 kPa (190 psi). After the vehicle is shut off if the engine coolant temperature at key-off is greater than 140C (284F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.
