So. I took the plunge and purchased a '98 Osmond Beal. On one of its first voyages, engine temp ran to 220 for maybe 2-3 minutes. I shut it down. A blown hose was the cause. Coolant everywhere. After allowing it to cool, I put about a gallon of water in the system (cause thats all i had) and ran for 60 more seconds; temp went from 150 to 200. I shut it down. Got towed. The engine never sounded funny, smoked, or sputtered. A learning experience for me. Here's where I stand. Gallons of light red coolant pooled below the engine. A gallon of water in the cooling system, that is otherwise empty. The hose that blew was as it turns out a Goodyear 5/8 hose headed back to the water heater. So my question is what should I do? Obviously change the hoses. I've tried to find the coolant I should be using, but I'm struggling. Should I empty the cooling system before filling. Should I change the oil. It had just been changed. Is there anything else I should do to make sure the engine is ok. Or, should I just hire a good mechanic? The engine is a 2007 Recon Cummins 5.9 BTA 370 HP. 400 hours. Thanks for your help.
