Hey yall I am in the process of buying my first Cummins. I'm looking at 5.9's and 6.7's. I know these questions will sound dumb, but hey we all start somewhere! First off what is an exhaust brake and when should it be used? How long should I let the engine idle in cold and hot weather? How do you idle down the engine? What is a good temp to shut down my engine and how do I know if I don't have aftermarket gauges (Dodge doesn't put egt temps in factory do they?) Finally where is a good place to fuel up at? I read the sticky but I still don't understand? I'm sorry but I did search and couldn't get direct information just technical questions and answers. Not general knowledge. :confused013: Thanks i'm just getting discouraged because I can't get any answers and I really want to make the switch from gas but I just want to do things right the first time!

Not good to let them idle very long even in cold weather, as it can wash down the cylinders. In warm weather 3-5 minutes. Cold weather I would give it 15 minutes. As far as shutdown temps, no they don't have a factory egt gauges. You have to install them, and somewhere around 300-350* is a good shutdown temp for the turbo. And exhaust brake is a brake installed in the exhaust the uses exduction pressure from the turbo to brake the engine. On the 6.7 engines, most of them have it as stock oem equipment, and can be turned on and used to help warm up the engine quicker. And the best place to usually fuel up, is a place that sells a lot of fuel like a truck stop. Make sure it is a truck stop or busy store you trust, and that they carry your normal brands of fuel. The more a tank is used, the better filtration it will have when you fill up, compared to an off the wall store whose tanks hold fuel for long periods of time. As long as you have good filtration on your truck, you won't have any problems with the fuel! :thumbsup:

Thank you very much that was quick! That pretty much answered all of my questions. I live in a big farming community and I see guys idle their trucks for hours especially in cold weather.
