Hello all,
While waiting for flagman to give go ahead, I was idling for maybe 8 minutes. The fan kicked on, and within 2 minutes, on the dash said SHUT DOWN!. Does that mean I need to add coolant, or is this engine not capable to idle in hot weather for more than 10 minutes.

After 3 minutes of not applying the brake or throttle, this message appears. Applying the brake or turning the throttle cancels the shutdown.

Thanks for the info
