Color Coding Under The Hood

You don’t have to be a mechanic to know your way around a car engine. Many modern cars have color-coded engines to make it super simple to know what you should keep an eye on between services, such as the dipstick, oil cap, coolant, brake fluid and washer fluid. That way, you know you can pretty much leave all the black and gray stuff to the experts. Although the color-coded bits tend to be yellow or blue on many cars, some engines have red and green parts too.
