1992 Saturn where the engine block heater plug is located 110 plug?

On a 1992 Saturn (SL, SC, or SW), the engine block heater plug, if equipped, is typically located on the driver's side of the engine block, near the bottom. It's often a fairly prominent, heavy-duty plug. However, not all 1992 Saturns came with block heaters. This was more common in colder climates where they were often factory-installed options or dealer-added accessories.

To be certain:

1. Check your owner's manual: This is the best source of information for your specific model.

2. Visually inspect the driver's side of the engine block: Look carefully near the bottom for a heavy-duty plug that looks like it's designed for an electrical cord.

3. Look at the wiring harness: Follow the wiring harness from the front of the vehicle, looking for a cord that terminates near the engine block.

If you can't find it, it's likely your Saturn wasn't equipped with a block heater.
