Cold Starts
I have an '07 5.9 CTD. It was cold yesterday morning about 44 degrees.
I turned the key waited for the coil light to go out, then started it. The grid heaters kicked on/off a few times then the engine went up to about 1000rpm's. I didn't touch anything to increase the idle, I don't think that I have the "high idle" feature enabled on my truck. Is this normal in cold weather to automatically idle up to about 1000rpms? |
yes this is normal for an 07........its a good deal too :U:

I just don't have too much cold weather experience; we might see an evening or two where it'll get down to the mid 20's. |
my 05 does that to
|
Has something to due with keeping the engine warm and to help prevent excess wear from idiling?
|
Thought that was standard fair on all 3rd gens?? 2nd Gens need to be flashed or have a Smarty installed/uninstalled.
|
The cruse control option is sure nice to run the rpm's up and down.:U:
|
I can tell you don't live in Calgary!! That is a normal feature of the 3rd gens, but it still is not enough to warm anything up other then the oil here in Calgary, it is a lot warmer here now then it has been in a couple weeks and it is currently -19 (-2 F). The truck won't even start warming up untill you have driven for atleast 10 minutes
|
Yeah, my 06 does it. First experience for me was about 2 months after I bought the truck, cranked it one cold morning and went back in the house. Heard it idle up and thought somebody was stealing it!
Nice feature.......once you figure out it's SUPPOSED to do that! |
Ya its a pretty nice feature and if you let it run long enough the idle will kick back down on it's own when it gets to a certain temp. The extra idle speed is nice to feed that turbo with a little more oil pressure as'well.
