i think so
i was riding onboard when he pulled over, the turn right before that there was a real, burble is the only way to describe it in the turn, it stumbled and i knew there was a problem
then sure-nuff happened again and he made the call, but sounded like it was a coolant issue other than the fire in the engine bay which said maybe otherwise
He said that He could smell it so I’m guessing Coolant.
