Oh great one,


Living in sunny California, and getting in the beast at 5:30am, the temp is about 60 deg.


Do I need to wait for the light to go out before starting it. The same goes for in the pm when it is 80-99 outside.


Thanks

You should really always wait for the wait to start light to go off before you start it. That is why they call it a wait to start light.

I've always wondered why. Fuel washing the cylinders? My old cummins intake heater did not even come on with high ambient temps.

My "wait to start" light almost never comes on after sitting 9 hours in a parking space where the air temp is 70* +. Some days I drive the gasser and some days the diesel. Every once in a while I forget I'm in the diesel and crank the starter right after inserting the key. It always starts, but I believe its always better to pay attention to the wait to start light.http://www.dieselplace.com/forum/smileys/Approve.gif

thanks,


You still don't really explain why. I thought it was to heat the glow plugs. Someone else said heat the air.


If I forget to wait, the truck still starts like a champ.

As the piston in a diesel engine compresses the air/fuel mixture in the combustion chamber, it is the heat of the compressed air that lights the fuel in a diesel engine. When the compressed air/fuel in a diesel engine are a certain temperature, the engine will start without assistance from glow plugs. http://www.dieselplace.com/forum/smileys/Geek.gif Rudolph Diesel had a great idea.http://www.dieselplace.com/forum/smileys/Big Smile.gif

Yeah what Mike said. It's an incredible idea.
