My 75 W600 has one. Was this a factory/dealer option? I don't think its listed on the underhood equipment sticker, but that's barely legible..... My truck was originally a plow/spreader truck & maybe the municipality/gov agency who first owned it had the heater added...... anyways, I plug it in & it still works, radiator makes a gurgling noise.
