Quick Answer. HowStuffWorks explains that food poisoning often occurs when a person eats spoiled food. Common symptoms of food poisoning are stomach pain, diarrhea, nausea, vomiting and cramping.
Confusion continues over coolant colors for cars. Of course, there is still the good old green stuff, but there is also orange, yellow (gold and amber), red, pink, blue and, if you mix the wrong things together, brown. Despite the rainbow of colors, all antifreeze starts out colorless.
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.
