Where is the block heater on a 2004 Toyota Echo?

On a 2004 Toyota Echo, the block heater is typically located on the engine block, near the oil pan. It is a small device with a power cord that can be plugged in to warm the engine, making it easier to start in cold weather. To locate it, you may need to look near the front or side of the engine, often on the passenger side. If your vehicle doesn't have a block heater installed, it may not be present, as not all models come with this feature.
