08 cummins engine in a Blue Bird All American, we had a problem this morning with all the coolant being blown out of bus in engine area, in the process of looking for leak we found 2 issues you need to watch.
1- top radiator hose at thermostat - bulgeing and swelling due to heat we figure and cracks leaking coolant
2 - heater hose from right rear corner of engine running up right side of engine to right front heater, we found loom melted to charged air line from turbo to air cooler and heater hose in that area swelled up and soft from heat

We ended up finding that driver was on a freshly oiled and stoned road and apparently a stone flew up and struck fan and went into radiator cutting a core
