When I start my truck up, I usually let it run for a minute before I take off, when I drop it in D and go it sounds like I can hear the fan or something like it kick on for about 10-20 seconds while accelerating and then it quiets back down. It usually only does it when I first start it up and take off. After it has run for a while, I shut it down and start it up again and drive, it doesn’t do it. It sounds just like when you hear a big rig take off from a start, you can hear the fan from the motor going. No check engine lights or anything. Who knows, maybe it’s normal. Just curious if that is something that anyone else has noticed with their Cummins?
