2014mp8 Posted August 31, 2021 Share Posted August 31, 2021 Hello, I have a 2014 mack with an mp8 445c. The truck is new to me with 436k miles, and just wanted some confirmation that what I’m seeing is normal. I noticed my oil temp is around 240-246 while cruising regardless empty or loaded. Oil pressure is fine during pull but it sits around 20 psi on idle. coolant temp is around 190-200ish are these to be concerned about? thanks!
