Does my car have power steering?

1964 1/2 ford mustang 6 cylinder with automatic transmission.

No it does not

It could, few did. Look for a power steering pump on the front of the engine. Or, with the engine running, turn the wheel as far as it can go. If you hear a belt squeal, then you have power steering.

Look under the hood. If there are hoses running from the column to a pump on the engine, you have PS.

My be your car don't have power steering.
