Hey everyone, I already did a search on topics/threads about engine block heaters, but I didn't find the info I was looking for. I have an 05 GT, and because it's a Canadian model, it's got an engine block heater. The thing that I'm wondering is, since the 4.6L is supposed to be a completely aluminum engine with steel sleeves (correct me if I'm wrong), can it have the block heater plugged in overnight? It's so damned cold up here lately (-35 or colder sometimes), that I'd like to leave the car plugged in overnight, rather than plug it in 1-3 hrs before I have to go to work in the morning (this would involve getting up at like 3am to plug it in everyday). I could have sworn that someone said that the block heater will over heat the coolant if plugged in overnight...meaning that it will let the coolant get hot enough to eventually find places to leak.

I'm sure that info I heard was bunk, but just wanted to find out from you engine guru's what should I do?

Thanks!

Maybe you could get it set up on some sort of timing circuit that flips it on at whatever time you want?

Yes, you can leave it plugged in overnight. That's what it was designed for. No, it won't overheat anything. It just like any other heater element in your iron, coffee pot, oven, electric water heater, etc. It has a built in thermostat. Once a certain temperature is reached, it trips and the heat stops. When the temperature drops enough, the circuit is closed again and the heat comes back on. It'll run through this cycle all night until you unplug it.[/align][/align]Do plug that baby up and enjoy faster heat in the mornings![/align]

It does warm up prety quickly. The easiest way is to have it hooked up to an outlet that you can turn on and off from inside the house. 1 hour should be pleanty. When you first get up turn it on, and by the time you go out the heater will blast you with hot air. You will also save on electricity.

They are madeto stay plugged in. When it gets cold enough I leave my 350 plugged in overnight with no problems, diesel doesn't like to be cold.
