Clamps loose on a new rig? Nah! Can't happen!
We sure found out that that is so wrong. On our shakedown voyage we had a sudden loss of pressure and the engine shut down. Not complete shutdown but no power. Check engine light and high temp came on. We were fortunately at an exit so coasted off the highway. Found antifreeze everywhere, including the front of the frog. Called roadside assistance who arranged for a tow. Fortunately the tow company had a mechanic/driver. He got up under the doghouse and found a hose clamp still in the locked open position. Pressure had finally blown the hose loose. He put hose and clamp back on, closed and locked the hose clamp and refilled the antifreeze. Back to normal.
