The block heater is standard in all PSD's, it is the cord that is optional in most states and standard in a few states that Ford considers cold weather states.

I was wondering why it was a $35.00 option.

personally i'm too lazy for this, so i actually do plug mine in when i get home and leave it on all night, but actually with the new injectors and new batteries, my truck fires up perfectly every morning now without it, even though it's actually colder out now.

On both of the Ford diesels I have owned (1995 & 2004), I plugged them in all night... even in Vegas were the temp the other morning was a whopping 40F!! I have noticed the block heater on the '95 warmed the block a heck of a lot more than on my 2004. Has anyone else noticed this or maybe I just have a faulty block heater.

It for sure cranks slower at those temps. I am not in that climatge all the time (I travel for work). Definately takes longer to warm up at those temps I start it and let it fast idle for 10-15 min before driving. I am sure you are right about being easier on engine and components, but when you are in the middle of nowhere with no way to plug it in you are just out of luck.

Surprisingly I just took took the factory batteries out and replaced them a month ago and the truck is an '03.

I feel your pain. When I head to the mountains in the winter there is no where to plug in. So i just make sure my batteries are in great shape. I am a little bit of a fanatic and I just changed my batteries in my 2006 to the yellow tops.

For those that state "it cranks slower" at low temps, what weight oil are you using? If it's THAT cold where you are, I'd be using a 5w40 or 10w30 as the manual says....
