    First Mack ever went to dealer since the fan always ran. I was told not the way it should be. Dealer changed everything to do with $3,000.00. They call late in the day to pick it up. I let it run for 45 minutes temp never went above 175 fan never shut off. Anyone have fan issues on your Pinnacle?
    Have to wait for them in the morning to see what their response is at the dealers. It's doing exactly what it was before I brought it in.
    Thanks for any replies

    I had that issue on a 17 Pete. It was a bad sensor on dpf. Engine wasn't running hot, but the sensor "said" the emissions system was too hot.
