With all of those caps under the hood, which one do you pour windshield wiper fluid in?

Answer The cap with a picture of a windshield

Before dumping your windshield wiper fluid into just any reservoir under the hood, make sure you have the right tank. The windshield wiper cap should have a literal windshield on it with drips. Due to its proximity to the antifreeze overflow compartment, a mistake will require you to fully flush your coolant.
