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.
1 If the coolant is low, use only DEX-COOL 50-50 mixture to add coolant. 2  DEX-COOL is bright pink, so it is easy to find in the auto parts store. 3  Never open the cap on the coolant reservoir or the radiator while the car is hot.
