Because it's embedded in the engine, you won't see a readily visible cord hanging down. You'll likely need to trace the cord from the power outlet (which might be near the front grille or bumper) to locate the point where it enters the engine block. The cord will usually have a connector and might be hidden behind some engine components.
To find it, you'll need to:
1. Locate the power cord: Start by looking for a heavy-duty cord extending from the front of the vehicle.
2. Trace the cord: Carefully follow the cord back towards the engine. You may need a flashlight and possibly to move some underhood components for better visibility. Be cautious of hot surfaces if the engine is warm.
3. Look near the thermostat housing and engine block: Once you've traced the cord as close as you can to the engine, carefully inspect the area around the thermostat housing and the sides of the engine block. The block heater element is usually a relatively small, cylindrical component.
Important Note: If you're not comfortable working on your vehicle, it's best to take it to a mechanic to have them locate the block heater for you. Incorrectly attempting to locate or plug in the heater could lead to injury or damage.
