While wrapping up a 4 hour job tonight at 6:00 pm we had pulled all hose from the house and as I was starting to go back in to collect turned to notice a HUGE cloud of steam coming from all around the truck. I went to truck to see if I could see water spraying anywhere and did not, I turned the truck to idle and steam stopped. Went ahead and collected while tech put stuff up. On the way to the shop I stopped at a vacant lot and checked oil, antifreeze, etc and saw no apparent problems, so I started it up and cranked her up to try to duplicate the steam issue and let it run for 15 minutes or so and everything appeared to be fine. I took off all the side panels while running to see if any hoses seem to have a split in them and found nothing.
Any ideas?
