This is my first winter with my Liberty diesel.  It never hesitates to start
immediately after the glow plug indicator goes out.  My only concern may be
totally unfounded, but I thought I'd ask this newsgroup:

Noisy as it is at cold start (and using B10) I've noticed that since the temp
has dropped this past week to -20C, or -4F, the noise it makes at the moment of
ignition is something like a load of lumber being dropped.  It is a VERY loud
"crack" and then settles down.  From then on it runs like a dream.  

I was just wondering if anyone else has one of these and is (finally) subjected
to sub-zero temperatures.  

Thanks

Sounds like my superduty in the morning. When it's this cold (-3F) I use th
eengine block heater overnight. Did you get one?

Yup, I have a block heater.  I've got a timer that's set for 1-hr ON- 1-hr OFF,
back and forth.  I was just wondering what's "normal" as far a diesel noise is
concerned.  It is warranted for 5 years, so if there was something not right,
then I'm sure it will fail long before that time.  It's just that initial racket
when starting that's different at below zero temps.

At these temps, an hour for the block heater isn't going to do a lot of
good. Best to leave it on overnight.

You don't have to leave it on all night.
What I do/did is buy a timer and have it come on 4 hours before
you normally leave for work or whatever. This works well for me
I also have a battery blanket warmer installed. On the coldest days
it starts up like it was tropical outside. And it's throwing heat
before I get to Tim Horton's for my morning coffee :-)
Next is an in-cab heater

I did that as well and found it warms up a lot quicker if it's left on
overnight especially if it's below 10F and windy.

They all do it. It's the computer controlling settings so it will start.
Since it was -4F how many cars didn't start and your crd did?

Good point.  I like that.  This little beauty is definitely a "start'n go". Runs
like a dream from dead cold on up.
