Glow Plug lights on a 6.4?

[judgesblind]

I live in central Texas where this morning it was 27 degrees. I went outside to start up my fathers 2008 6.4L and the glow plug light in the middle of the dash stayed on for about 3 seconds. Is this just because of the cold weather because I understood that there was never supposed to be any wait on the plugs? But hey I could be wrong.

Yes it's suppose to do that. I'm actually surprised it didn't stay on longer. I live in north Texas and when it was about 25 where I was the light stayed on for about 10 seconds.

Mine really doesn't start to stay on noticeable longer until it gets below 10 degrees outside. Its still nothing like a 7.3, 6.0, or 5.9 when it comes to difficulty starting in cold weather.

Now that I plug it in, the light just about flashes and that's it.

yeah my 6.0 i have to wait a good 10 seconds or something like that and i went to start my dads in 20 degree weather not plugged in and it was on for a second if that

Mine stays on for about 15 to 20 seconds when the weather dips below 30.

A couple weeks ago it got down to about 15 degrees at night and I had been oout of town for a couple days. Light stayed on for about 45 seconds before it finally went off. Truck fired right up. Truck has never been plugged in, but thinking about getting the kit to be able to do so.

that seems real long for a 6.4, mine have never been on for more then 5-10 seconds. and it gets real cold up here.

Mine will stay on a good 10 sec when it gets really cold outside. Then I wait another 10 secs after the light goes out before I start mine. The glow plugs cycle to my understanding 30 sec after the light goes out just like all the international motors always have. I guess its just good practice and habbit from my 7.3L owning days.

It's normal for my glow plus to stay on for long periods of time especially when the weather is at -35c! Even being plugged it stays on for a bit!

my dads 2010 stays on for about 1-2 seconds if it has sat for more than 24 hours. once you drive it once that day we never see the light again.

only be in the high 20's a few times so far this winter, but it hasn't got passed a few seconds so far. my 6.0 stays on for easily 8-10 seconds in the same situation.

My truck glow plugs light only turns on for 1 to 2 seconds, but my truck has only seen 39* here in MIAMI
