Well I found a 1995 Isuzu NPR (Turbo Diesel) I have a few questions because it did not include an owners manual although I just ordered one, it wont be here for a couple days. My first question is what do I really need to watch out for on these trucks? Is there anything that I need to pay very close attention to? Also I have not ever owned a diesel engine before so the whole diesel thing is completely new to me. My second question is there is a button that lights up when you push up on the lever that controls the windshield wipers, what is this? And last but not least there is a button located on the dash that you push and it shows a transmission symbol..maybe, what is this? Guys im sorry these questions are so vague, but this is brand new stuff to me lol Thanks for the help!
