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.
Luckily it only takes a second to check your coolant level. Most cars these days have a translucent coolant overflow tank right next to the radiator. It's white plastic, but you can see inside to see if there's enough juice to keep things safe. You'll also see markings on the side telling you the low and high levels to work with. Always check your coolant level when the car is cold. If you happen to have an older vehicle without a visible overflow and fill tank, you'll have to check the antifreeze / coolant level by looking into the radiator. There is no dipstick or other meter to tell you whether you have enough coolant in the radiator on these older vehicles.
