The block heater on a 2004 Ford Escape (if it has one – not all models came equipped) is located in the
engine block, typically
on the passenger side, near the
thermostat housing. It's usually a threaded plug with a cord that exits through a grommet somewhere nearby. Because it's embedded in the engine block, you may need to visually inspect the engine to find it – it won't be something easily visible from the outside.
Important Note: Not all 2004 Ford Escapes came with block heaters. This was an optional feature, particularly in colder climates. If you can't find it, your vehicle may not have one installed. Check your owner's manual to confirm if your specific model and trim level included this feature.
