Question

[Brews]

I just purchased a 2001 Silverado with the 6.6 Duramax. I'm can't seem to locate the plug I would use to warm the block when the weather turns cold. From what I read it should be located near the power steering. Is it possible this truck didn't come with this option? At what temp would/could this become an issue?

im not 100 percent sure but i think its an option so it might not have one

Water freezes at 32 deg F. Antifreeze will let you go lower. If you get consistent temps in the 30's I'd say that a block heater is cheap insurance.
Here are a couple of images of the cord. It will be zipped tied in the engine compartment topside.
