Where is the radiator cap on 1999 Chrysler LHS?

The radiator cap on a 1999 Chrysler LHS is located on the top of the radiator, typically towards the front of the engine compartment. However, because of variations in engine type and potential aftermarket modifications, it's best to visually inspect the top of the radiator itself. Look for a pressure cap, usually black plastic, that's fairly easily accessible. It will likely be near the upper radiator hose connection.
