I am new to diesel engines and just want to make sure I am starting up my truck without hurting anything. I have always had the understanding you were supposed to turn the key 2 clicks and let the glow plugs "warm up" for a few seconds before starting the truck. However when I bought the truck they told me that you don't need to do that anymore on these trucks. Just want to make sure that is correct. I have remote start and have been hesitant to use it because I have been doing the glow plugs thing for now until I know for sure that I don't need to do that anymore. Any advice is appreciated. Again, my first diesel so sorry if this is an ignorant question.
