Yes, generally, you can leave a block heater plugged in for about two to four hours before you plan to start your vehicle. This duration is usually sufficient to warm the engine, making it easier to start in cold weather. Leaving it plugged in for longer periods typically doesn’t provide additional benefits and can lead to unnecessary energy consumption.
