Where is the radiator cap on a 2003 ford ranger located?

On a 2003 Ford Ranger, the radiator cap is typically located on the top of the radiator, at the front of the engine compartment. It's usually a black, plastic cap. However, because there are different engine options for that year, it's *best* to visually look for it in that general area. It might be slightly obscured by other components. Be cautious when checking as the system may still be under pressure even when the engine is off.
