The radiator drain plug on a 1992 Chrysler LeBaron is located at the
bottom of the radiator, typically on the
driver's side (left). However, it's
not always easy to see and might be hidden somewhat behind other components. You'll likely need to get down low and possibly use a flashlight to locate it.
It's usually a small, threaded plug, often brass or plastic. Be prepared to get some coolant on you, and have a drain pan ready to catch the fluid. Remember that coolant is toxic, so proper disposal is essential.
